Caffeine-Free Pre-Workout

What is IO Genix PreWork NOSTIM?

IO Genix PreWork NOSTIM is a complete caffeine-free pre-workout powder, dosed at 16 g per serving. “NOSTIM” means exactly what it says: no central nervous system stimulant in the formula, no caffeine, no synephrine, no yohimbine.

What sets it apart from most stimulant-free products is that it doesn't stop at the pump. The formula packs in 4 g of beta-alanine, 3 g of creatine monohydrate, 3 g of AAKG, taurine, tyrosine, four vitamins and 375 mg of magnesium. That's a 16 g serving, two to three times the weight of a conventional pre-workout, and you can see it in the shaker.

The flavours listed are Raspberry Lemonade and Watermelon. The number of servings per tub is not published by the manufacturer in the information available to us. The rest of the Spanish range is in our IO Genix section.

What does a 16 g serving contain?

The per 100 g values are calculated from the manufacturer's declaration for a 16 g serving. The “protein” line corresponds to the free amino acids in the formula, counted here by the manufacturer.

4 g of beta-alanine is at the top end of the market and it deserves an explanation that changes how you use the product. Beta-alanine does not act when you take it: it gradually raises muscle carnosine stores, which takes several weeks of daily intake. A pre-workout taken three times a week never gets you to that level. If that is the effect you are after, you need to top up on non-training days with beta-alanine on its own. The immediate effect, on the other hand, is guaranteed: tingling in the face and forearms within about fifteen minutes. It is harmless and it fades as you get used to it.

The same remark applies to the 3 g of creatine monohydrate. It is a decent dose — the useful range runs from 3 to 5 g — but creatine works by saturating the muscle, which means taking it daily, rest days included. Taken only before training, it never fills the tank completely. That is not a flaw in the product, it is a limitation of the format.

The 375 mg of magnesium covers 100% of the reference value, and magnesium contributes to normal muscle function, to the normal functioning of the nervous system and to the reduction of tiredness and fatigue. It is the only active in the formula that carries a claim of any use here. One caution though: 375 mg in one go is a high amount for a single serving, and magnesium has a well-known laxative effect above 300 mg. If you are already taking magnesium elsewhere, count it in.

The 3 g of AAKG provides arginine bound to ketoglutarate. The effective arginine content is not published, and neither arginine, nor beta-alanine, nor taurine, nor tyrosine holds an authorised claim in Europe. Creatine does hold one, from 3 g per day, but it assumes daily intake, which this product alone does not allow. Vitamins B1, B3, B6 and C, at 100% of their reference value, contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue.

Ingredients list

Beta-alanine, AAKG (arginine alpha-ketoglutarate), creatine monohydrate, L-taurine, L-tyrosine, magnesium (bisglycinate), natural flavourings, acidity regulator (citric acid), vitamins B1, B3 and B6, vitamin C (ascorbic acid), BioPerine® (black pepper extract standardised to 95% piperine), sweetener (sucralose), anti-caking agent (silicon dioxide). May contain traces of GLUTEN, MILK, EGG, SOYA and NUTS. Made in a facility that handles these allergens.

How do you take PreWork NOSTIM?

Serving: 16 g. Liquid: 200 to 250 ml of cold water. Timing: 30 minutes before training. Frequency: one serving on each training day. Duration: no break period needed, as the absence of stimulants rules out any build-up of tolerance.

Start with a half serving of 8 g for three to five sessions. The manufacturer recommends it and it is right to: 4 g of beta-alanine in one go, in someone who has never taken any, produces tingling pronounced enough to be alarming. And 375 mg of magnesium in one go, on a stomach that isn't used to it, can cut a leg session short for all the wrong reasons.

The liquid volume given, 200 to 250 ml, makes for a fairly concentrated drink. Nothing stops you going up to 400 ml if you prefer, and it is easier on the stomach that way. Do avoid taking it straight after a high-fibre meal, which slows absorption of the whole thing.

The real appeal of the product is about timing. With no caffeine, it works just as well at 20:00 as at 8:00, with no consequences for falling asleep. That is why we regularly recommend it to people who only have an evening slot to train and who have ended up giving up on conventional pre-workouts.

Who is PreWork NOSTIM for, and who is it not for?

It suits anyone who trains late, anyone sensitive to caffeine, anyone who wants a break from stimulants without losing the pre-session ritual, and anyone who would rather have a single product than three tubs to measure out separately.

It is not for you if you are looking for energy or alertness: with no stimulant there is no kick, and disappointed feedback almost always comes from that. Nor is it for you if you already take creatine daily — you would be doubling up for nothing — or if you already take 300 mg of magnesium elsewhere.

The product is made in a facility that handles gluten, milk, egg, soya and nuts: with a severe allergy, that point alone rules it out. Like any product in this category, it is for adults only, not recommended for pregnant or breastfeeding women, and calls for advice from a healthcare professional if you are on medication or have a known condition. If you are subject to anti-doping testing, check the batch status with your federation.

What you should not expect from it: the 4 g of beta-alanine will only deliver its full effect if you take it every day, training or not, for several weeks. The same goes for the creatine. Used only on training days, this product works mainly as a preparation and comfort drink — which is still useful, but it is not what the sum of the stated doses promises.

PreWork NOSTIM or a caffeinated pre-workout?

The difference is clear-cut and comes down to what time you train.

A caffeinated pre-workout acts on alertness, focus and perceived effort. It is the better choice for a heavy session, a morning workout, or a day when motivation is missing. Its downside is well known: caffeine stays active for five to six hours, and a session at 19:00 is paid for at night. It also forces you to cycle, since tolerance sets in within a few weeks.

NOSTIM does not do that job. It supplies substrates — beta-alanine, creatine, arginine, magnesium — rather than a nervous signal. It is the better choice for evening sessions, for periods when you want to cut back on caffeine, and for someone who trains every day and cannot cycle a stimulant. It also has an advantage that is rarely pointed out: no break is needed, so you can use it all year round without losing the effect.

There is a third route if you already take your creatine separately: creatine-free pre-workouts avoid the overlap. And if it is arginine alone that interests you, our L-arginine section offers it at a serious dose.

Frequently asked questions

Why do I get tingling after taking it?

That's the beta-alanine, and at 4 g per serving the sensation is pronounced. It affects the face, the scalp and the forearms, appears within ten to fifteen minutes and lasts about half an hour. It is harmless, well documented, and it fades as the body gets used to it. Starting on a half serving is enough to tame it.

Can you take it in the evening?

Yes, that is the whole point of it. No stimulant goes into the formula, so it has no bearing on falling asleep. It is the only type of pre-workout we recommend for a session at 20:00 or 21:00.

Should you take extra creatine?

If you want the full benefit of creatine, yes. It works by saturating the muscle, which means taking it daily, rest days included. The 3 g in here is only enough if you train every day. Otherwise, top up with 3 g on non-training days.

Is 375 mg of magnesium too much for a single serving?

It is a high amount for a single intake. Magnesium has a well-known laxative effect above 300 mg taken at once, and not everyone reacts the same way. That is one more reason to start with a half serving, and not to stack it with another magnesium supplement on the same day.

How long before training should you take it?

Thirty minutes. That is longer than for a product aimed purely at the pump, because the whole thing needs time to be absorbed. Taking it five minutes before you start amounts to training while you digest.

Do you need to take breaks from it?

No, and that is a genuine advantage. The cycles imposed on conventional pre-workouts exist to restore caffeine sensitivity. With no stimulant, that problem doesn't arise: you can use it continuously for as long as you keep training.

Does the product contain sugar?

Very little: 3.1 g of carbohydrate per serving, for 52 kcal in total. The sweetness comes from sucralose. It is a negligible load, even during a calorie deficit, and it does not interfere with fasted training.

Where can you buy IO Genix PreWork NOSTIM?

The flavours can be ordered from this page, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, this is the product we put in the hands of people who train after work and who describe broken nights since they went back on a pre-workout: the problem rarely comes from the training itself. The rest of the pre-workout section can be browsed in our sports nutrition range.

What is Nutrend Pump Pre Workout?

Nutrend Pump Pre Workout is a caffeine-free pre-workout powder, sold in a 225 g tub covering 15 servings of 15 g. Nutrend is a Czech brand, present in Europe since the early 1990s, and this formula is one of its rare products aimed at late-in-the-day sessions.

The composition reads in three blocks. The pump first, with 5 g of citrulline malate and 3 g of beta-alanine. Then the cognitive side: 1 g of L-tyrosine, 200 mg of choline, 300 mg of Bacopa monnieri extract and 500 mg of KSM-66 ashwagandha standardised to 5% withanolides. And finally a base of B-group vitamins, with sodium and taurine.

The flavours on offer: Rainbow, Berry Splash and Tropical Blend. The product joins our caffeine-free booster and Nutrend sections.

What does a 15 g serving contain?

Almost everything is quantified, which is not all that common. The one grey area is taurine, whose content varies from 256 to 818 mg depending on the flavour — that is how the manufacturer declares it, and we will not decide in its place. The “of which sugars” line is not published.

Three figures to remember. The 3 g of beta-alanine first: that is a straightforward dose, above what is usually found, and you should know that at that level the tingling is all but guaranteed. Then the 5 g of citrulline malate: a decent dose without being a record, sitting within the useful range. And the 500 mg of KSM-66 ashwagandha, a patented extract standardised to 5% withanolides — stating the standardisation is what sets a serious extract apart from any old plant powder.

On the claims, here is what European regulation authorises and what we can therefore write: vitamins B1, B3, B5 and B12 contribute to normal energy-yielding metabolism, vitamins B3 and B12 contribute to the reduction of tiredness and fatigue, choline contributes to normal lipid metabolism and to the maintenance of normal liver function from 82.5 mg per portion — the 200 mg in this formula clear the threshold. By contrast, no claim is authorised for citrulline, beta-alanine, tyrosine, taurine, ashwagandha or bacopa.

How should Nutrend Pump be dosed?

Dose: 15 g, that is half a scoop, never more than 15 g a day. Fluid: 250 ml of cold water. Timing: 30 minutes before the session. Frequency: on training days only. Duration: continuous use is possible, with a 1 to 2 week break after 8 to 12 weeks of use.

Mind the dose: the scoop supplied holds 30 g, the serving is 15 g, that is half of it. This is the kind of detail that doubles your consumption without your noticing.

Two practical points. The formation of small lumps in the powder is normal: amino acids are hygroscopic and pick up moisture from the air, and nothing is affected by it. And expect tingling on the face and extremities in the minutes after taking it: that is the paraesthesia linked to the 3 g of beta-alanine, it lasts 15 to 30 minutes and has no consequences.

Once the tub is open, use it within 3 months. Keep it closed, dry, at a temperature not exceeding 25 °C. The shelf life before opening is 36 months.

Who is this pre-workout for, and who is it not for?

It targets three profiles. Those who train in the evening and refuse to sacrifice their sleep. Those who are sensitive to caffeine — palpitations, anxiety, shaking — and have given up on conventional pre-workouts. And those already taking caffeine elsewhere in the day who do not want to stack it.

The restrictions are brief but real. The product is not recommended for children, adolescents, pregnant or breastfeeding women. People on medical treatment should consult a healthcare professional before use — the presence of ashwagandha and bacopa warrants that caution, and piperine alters the metabolism of many medicines. The product may contain traces of SOYA and MILK.

What not to expect from it: energy. Without caffeine there is no kick, and that is the most frequent misunderstanding in this category. Nor should you count on ashwagandha or bacopa for any noticeable effect during the session: these plants are judged over weeks, not over thirty minutes, and no European claim is recognised for them. What the formula delivers is pump and preparation for the effort — nothing more, nothing less.

Nutrend Pump or a pre-workout with caffeine?

The two answer different problems, and the question to ask yourself is a simple one: what is it you are missing before the session?

A pre-workout with caffeine, like those in our boosters section, is the right choice if what you are missing is the will to go. A session at 6:00, a heavy week, motivation at rock bottom: nothing other than caffeine fixes that, not citrulline, not beta-alanine. Those formulas typically supply 200 to 400 mg of caffeine, and often doses of citrulline equal to or higher than the ones here.

Nutrend Pump wins on ground that caffeine cannot occupy: the clock. At 20:00 before a 20:45 session, it is the only type of product that will not cost you your night — and sleep weighs more heavily on progress than any pre-workout. It also wins on the 3 g of beta-alanine, a dose higher than in many stimulant formulas, and on the presence of a standardised ashwagandha extract rarely found in a pre-workout. Many of our customers end up with both tubs and alternate according to the time of the session.

Frequently asked questions

How many servings are in the 225 g tub?

Fifteen servings of 15 g. At three sessions a week, one tub covers five weeks. Once opened, it should be used within three months as the manufacturer recommends.

Does the scoop correspond to one serving?

No, and that is the trap with this product. The scoop supplied holds 30 g; the serving is 15 g, that is half a scoop. Taking a full scoop would amount to doubling every dose, including the 3 g of beta-alanine.

Why is the tingling so pronounced?

Because the formula contains 3 g of beta-alanine, a high dose. The paraesthesia appears within 15 minutes, affects mainly the face and extremities, lasts half an hour and has no known consequences. It eases with regular use; if it bothers you, cut back temporarily to 10 g.

Can it be taken just before sleeping?

The formula contains no stimulant, so nothing stands in the way as far as sleep goes. That said, the product is only of interest taken 30 minutes before a session: taking it without training serves no purpose.

Why does the taurine vary by flavour?

The manufacturer declares a range of 256 to 818 mg depending on the flavour, without explaining why. We repeat that information as it stands and flag the imprecision rather than putting forward a single figure.

Are the lumps in the powder normal?

Yes. Amino acids are hygroscopic: they pick up moisture from the air and form small clumps. The manufacturer states this explicitly, and it affects neither the composition nor the effectiveness. Close the tub properly after each use.

Can it be combined with a fat burner or a coffee?

Technically yes, since it supplies no caffeine. But that cancels out the point of the product: if you are after stimulation, you may as well take a conventional pre-workout and pay only once. The manufacturer recommends avoiding it alongside caffeinated products.

Where to buy Nutrend Pump Pre Workout 225 g?

The flavours can be ordered from this page, and we ship throughout France and Europe. It is a product we systematically suggest to customers who tell us they have given up pre-workouts because of their sleep: many have no idea the caffeine-free category exists.

Our Vendargues shop, about ten minutes from Montpellier, keeps the flavours on the shelf, and it is also the place where someone will show you where half a scoop stops. The rest of the pre-session range can be browsed from sports nutrition.

What is Rule One PUMP?

Rule One PUMP is a caffeine-free pre-workout powder, built around a single objective: the muscle pump. It contains no stimulant — no caffeine, no yohimbine, no synephrine — so it is not trying to wake you up. It works on circulation and cell hydration, not on the nervous system.

The formula is fully transparent: every active is listed with its quantity, with no proprietary blend hiding the doses behind an overall total. That is still rare enough in this category to be worth pointing out, and it is the first thing to look at on a pre-workout. Rule One is an American brand whose other products are in our Rule One section.

The flavour offered here is Blue Razz Lemonade. One useful detail: the manufacturer's documents mention an unflavoured version, with no flavouring or sweetener, meant to be added to another product. It is not stocked by us at present — only the flavoured version appears on this page.

What does a serving of Rule One PUMP contain?

Here are the actives declared per scoop, in decreasing order of quantity.

Two pieces of information are missing from what the manufacturer publishes, and we are not going to invent them: the exact weight of the scoop in grams, the number of servings per tub, along with the energy and macronutrient values. The label on the tub you receive is the reference on those points.

3 g of citrulline is a straight dose. Plenty of pre-workouts put citrulline at the top of the list and then include 1 g of it, which achieves very little. Here the quantity matches what is actually used in the performance literature. Note that this is pure citrulline and not citrulline malate: for the same stated quantity, pure citrulline delivers more citrulline, since malate accounts for around 40% of the weight in a 2:1 ratio. If you are comparing with another product, compare like with like — our citrulline section lets you do the maths.

The 2 g of taurine plays a different role: taurine takes part in the osmotic balance of the muscle cell, in other words in how much water it holds. That is the second lever behind the feeling of a pump, and it is also what separates a formula designed for volume from a formula designed for energy. The taurine section offers it on its own for anyone who wants to add it to another base.

Nitrosigine® supplies arginine in a form complexed with inositol and silicon. A word of honesty: 500 mg of an arginine complex is not 500 mg of arginine, and the manufacturer does not publish the exact share. If it is arginine at a straight dose that interests you, take a look at our L-arginine section instead.

Finally, a regulatory point that belongs here and nowhere else on the page: none of these ingredients holds a health claim authorised in Europe. Not citrulline, not arginine, not the plant extracts in the S7 complex. We can describe what they are and what the doses are worth compared with the market; we cannot attribute a health effect to them, and legally nobody can.

Ingredients list

L-citrulline, taurine, Nitrosigine® (inositol-arginine silicate), natural and artificial flavourings, citric acid, S7™ (green tea extract, turmeric extract, garlic extract, blueberry extract, broccoli extract, tart cherry extract, kale extract), whole grape extract, pine bark extract, astragalus extract, panax ginseng extract, AstraGin® (astragalus root extract, panax notoginseng root extract), sweetener (sucralose), food colouring. Made in a facility that handles MILK, EGG, SOYA, WHEAT, PEANUTS, NUTS, FISH and CRUSTACEANS.

How do you take Rule One PUMP?

Serving: one scoop. Liquid: 240 to 350 ml of cold water. Timing: 15 to 20 minutes before the session. Frequency: one serving on each training day, not on rest days. Duration: the manufacturer gives no course length; use follows your training calendar.

For a first tub, start with half a scoop. This is not caution for its own sake: a full dose of citrulline causes digestive discomfort in a minority of users, and it is better to find that out with 1.5 g than with 3 g just before a leg session.

The volume of water matters more than you would think. Below 240 ml the drink is concentrated, sharper on the palate, and the desired effect — drawing water into the muscle — has less raw material to work with. If you train in a hot gym, go up to 400 or 500 ml without hesitation.

There are two ways to use it. On its own, it is a late-session pre-workout: no stimulant, so no impact on falling asleep, which makes it one of the few products in this category you can use at 21:00. As an add-on, a scoop goes into your usual pre-workout to reinforce the pump side without adding a single milligram to the total caffeine. That is the most common use among our customers who train in the morning.

Who is Rule One PUMP for, and who is it not for?

It suits anyone who trains in the evening and does not want to sacrifice their sleep, anyone already at saturation point with caffeine during the day, and anyone looking for the sensation of a pump rather than a kick. It also suits those who build their own pre-workout by stacking separately dosed components.

The product is for adults only. It is not recommended for pregnant or breastfeeding women, and calls for advice from a healthcare professional if you have a condition or are on medication — the question is worth asking if you take anything acting on blood pressure, since the mechanisms involved concern vascular tone.

It is not for you if you are looking for energy: with no caffeine, it wakes nobody up. A lot of disappointed feedback comes from that, from a purchase made without reading the label. Nor is it for people allergic to the major allergens, since production is shared with milk, egg, soya, wheat, peanuts, nuts, fish and crustaceans.

What you should not expect from it: the pump is a transient phenomenon, not progress. It makes the session more enjoyable and the mirror more flattering for an hour; it does not build muscle by itself. If your training and your diet do not follow, no product in this category will make up for it. And if you feel nothing, that is not abnormal: the response to citrulline varies a great deal from one person to another.

Rule One PUMP or a pre-workout with caffeine?

That is the real trade-off, and it depends on what time you train.

A conventional pre-workout combines caffeine, beta-alanine and often citrulline. It acts on alertness, perceived pain and aggression under the bar. It is the better choice for a morning session, for heavy training where focus is the limiting factor, or when you are tired and the session risks being rushed. Its downside is mechanical: caffeine has a half-life of five to six hours, which writes off part of your sleep when you train after 18:00.

Rule One PUMP does not do that job and does not claim to. Its ground is the end-of-day session, the volume session where you are chasing sensation rather than heavy loads, and the period when you want a break from stimulants without losing the habit of the pre-session ritual. It also has the advantage of stacking: nothing stops you adding it to a pre-workout on days when you want both.

If you are still hesitating, there is a third family: creatine-free pre-workouts, for those who already take their creatine separately and do not want to see it come back in the pre-workout.

Frequently asked questions

Does Rule One PUMP contain caffeine?

No, none at all. That is the whole point of it: the entire formula is built without stimulants, which means you can use it in the evening with no consequences for falling asleep. It is also why you do not “feel” anything come on within ten minutes, unlike a caffeinated pre-workout.

Can you mix it with your usual pre-workout?

Yes, and it is a common use. A scoop added to your pre-workout reinforces the pump side without adding caffeine. Just check that your pre-workout does not already contain 6 g of citrulline, in which case the total would go beyond what is of any use.

How long before training should you take it?

15 to 20 minutes. That is shorter than for a caffeinated pre-workout, which needs more like 30 to 45 minutes. Citrulline acts quickly, and waiting an hour tends to lose the benefit rather than reinforce it.

What is the difference between citrulline and citrulline malate?

Citrulline malate is citrulline bound to malic acid. In a 2:1 ratio, around 60% of the stated weight is citrulline and the rest is malate. The 3 g of pure citrulline in this product therefore equates to around 5 g of citrulline malate. That is the calculation to do before comparing two labels.

Does the product cause water retention?

It draws water into the muscle cell, which is the desired effect, and not under the skin, which would be the unwanted one. The difference comes down to sodium and not to the actives in this formula. In practice, you should not see your weight climb or your face puff up.

Can you take it on rest days?

There is no point. Unlike creatine, whose benefit depends on muscle saturation built up over time, the actives in this product act when you take them and no further. A tub therefore lasts longer than you might think.

Does S7 really do anything?

There is no way to say so. 50 mg of a blend of seven plant extracts amounts to a few milligrams of each, and the manufacturer does not publish the breakdown. It is a patented ingredient with a proprietary dossier, not an active dosed at the level you would find in a study. The two ingredients that genuinely carry this formula remain citrulline and taurine.

Where can you buy Rule One PUMP?

It can be ordered from this page, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, this is the product we reach for when someone comes in and tells us they have not been sleeping since they went back to the gym in the evening: nine times out of ten the cause is in their pre-workout, and switching to a stimulant-free formula sorts it out within a week. The rest of the pre-workout section can be browsed in our sports nutrition range.

What is FULL AF by 5% Nutrition?

5% Nutrition Rich Piana FULL AF is a pre-workout with no stimulants whatsoever. No caffeine, no stimulant extracts: the formula is built solely around muscle pump and cellular hydration. It is a category in its own right, often misunderstood, and this product is one of its most heavily dosed representatives.

Five active ingredients make up the formula: 8 g of L-citrulline, 2 g of L-taurine, 2 g of GlycerSize™ (65% glycerol), 2 g of anhydrous betaine and 750 mg of Nitrosigine® (inositol-stabilised arginine silicate). Everything is quantified, there is no proprietary blend — rare enough in this section to be worth pointing out.

The flavours on offer: Wildberry, Push Pop and Blue Raspberry. The product appears in our caffeine-free booster section, and also stands comparison with the formulas in the creatine-free pre-workout section.

What does one serving of FULL AF contain?

The manufacturer publishes neither the macronutrient breakdown, nor the salt content, nor the number of servings per tub: we are flagging that rather than estimating it. The 60 kcal come mostly from the glucose polymers used as a carrier.

The figure that makes this whole page is the 8 g of citrulline per serving. For context: ordinary pre-workouts provide 1 to 2 g, serious formulas 4 to 6 g. Very few products reach 8 g, quite simply because citrulline is expensive and takes up room in the scoop. At that dose, the price of the tub explains itself.

One regulatory point is interesting, and rare in this category: betaine has an authorised claim in Europe — it contributes to normal homocysteine metabolism, from an intake of 1.5 g a day. The 2 g in this formula exceeds that threshold. The regulations require it to be stated that a daily intake in excess of 4 g may significantly increase blood cholesterol levels: at 2 g per serving and one serving a day, you stay below that, but the information has to appear. For citrulline, taurine, glycerol and arginine, no claim is authorised.

How should you dose FULL AF?

Serving: 1 full scoop, without exceeding one a day. Liquid: 250 to 350 ml of cold water. Timing: 30 minutes before training, preferably on an empty stomach. Frequency: one serving a day. Duration: the manufacturer gives no cycle or mandatory break — logically enough, since there is no stimulant to build tolerance to.

One particular feature of this product: it can also be taken on rest days, in the morning on an empty stomach. The manufacturer recommends this to maintain the sensation of muscle fullness, and it is a use that would make no sense with a stimulant pre-workout.

Drink plenty. This is not a throwaway piece of advice: glycerol works by holding water, and without a sufficient fluid intake the formula cannot do anything. Allow at least an extra half a litre on the day you use it.

The manufacturer also states that it is possible to pair it with a stimulant pre-workout, by taking FULL AF thirty minutes beforehand. It is a common combination among advanced users: the pump on one side, the energy on the other. If you do it, add up the caffeine from the second product, not from this one — it has none.

Who is FULL AF for, and who is it not for?

It is aimed at three clearly identified profiles. Those who train in the evening and do not want to sacrifice their sleep. Those who are sensitive to stimulants — palpitations, anxiety, tremors — and have given up on conventional pre-workouts. And those who work in long sets, in the 8 to 12 rep range, and are after the sensation of a pump.

The restrictions are shorter than on a stimulant product, but they exist. For adults over 18 only. Not recommended for pregnant or breastfeeding women. Consult a healthcare professional before use if you are on any medical treatment. Do not exceed one scoop a day. The product contains COCONUT derivatives, which rules it out if you are allergic to tree nuts. It also contains FD&C Yellow No. 5, tartrazine, for which European regulations require the statement: may have an adverse effect on activity and attention in children. Finally, do not use the product if the safety seal is damaged.

What not to expect from it: energy. That is the most frequent misunderstanding about this product. Without caffeine, you will feel no kick, no heightened alertness, nothing edgy. You may feel your muscles fuller, and that is all the formula is aiming for. Nor should you expect strength or muscle from it: a pump is a sensation, not a result.

FULL AF or a stimulant pre-workout?

The two do not replace each other, and the best advice we can give is to work out which of the two problems you are trying to solve.

A stimulant pre-workout is the right choice when the problem is finding the will to go. A session at 6:00 in the morning, a heavy end to the week, motivation at a low ebb: caffeine is what solves that, and nothing else. The formulas in the pre-workouts section typically provide 200 to 400 mg of caffeine, often with more modest citrulline doses. They also win on price: citrulline costs more than caffeine, and a tub with 8 g per serving has to be paid for.

FULL AF wins as soon as stimulation is not the point, or is itself the problem. On citrulline alone, it is ahead of just about everything we sell, including the most expensive formulas. It also wins on flexibility: it is the only type of product you can take at 20:00 without a second thought, or on rest days. The isolated ingredients that make it up — taurine, L-arginine — are also available separately if you would rather put together your own blend, but at 8 g of citrulline per serving, the sums rarely work in your favour.

Frequently asked questions

How many servings does a tub contain?

The manufacturer does not publish the net weight or the number of servings in the data supplied, and we will not estimate it. The information is on the packaging: read it when it arrives. The serving is one full scoop, once a day at most.

Is there really zero caffeine?

Yes. The formula contains neither caffeine nor any other stimulant, and the manufacturer states so explicitly. That is precisely the point of the product: it can be taken late in the day with no consequences for sleep.

What is the glycerol in the formula for?

GlycerSize™ is a 65% glycerol powder, dosed at 2 g. Glycerol holds water in the tissues, which explains the instruction to increase hydration that comes with the product. No health claim is authorised in Europe for glycerol: we describe its role in the formula without attributing any regulated effect to it.

Can it be combined with a stimulant pre-workout?

Yes, and the manufacturer even recommends it: take FULL AF thirty minutes before the stimulant. Since it provides no caffeine, there is no risk of stacking on that front. Just check the caffeine dose of the second product, which remains subject to the usual guidelines.

Can it be taken on days without training?

The manufacturer says so: one serving in the morning on an empty stomach on rest days. It is a possible use, specific to non-stimulant formulas. That said, if your budget is tight, keep the product for training sessions: that is where it makes the most sense.

Do you need to drink more than usual?

Yes, at least 500 ml more on the day you use it. Glycerol works by holding water: if you are already short on fluids, the formula cannot work and you mostly risk headaches. A bottle next to the bench is not optional here.

Does it contain allergens?

Yes, it contains coconut derivatives, which rules it out if you are allergic to tree nuts. It is, on the other hand, declared gluten-free and free from artificial colours with the exception of FD&C Yellow No. 5.

Where can you buy FULL AF by 5% Nutrition?

The flavours can be ordered from this page, and we ship throughout France and Europe. It is a product we often recommend to customers who tell us they have stopped taking pre-workouts because of sleep or palpitations: most of them do not know this category exists.

Our Vendargues shop, about ten minutes from Montpellier, is also the place to compare citrulline labels side by side — that is generally the moment when the gap in dosing becomes obvious. The full range can be found in the 5% Nutrition collection.

What is Naughty Boy PUMP?

Naughty Boy PUMP is a pre-workout that is caffeine-free and completely free of stimulants, formulated by the British brand Naughty Boy. The dose is one 16 g scoop, and eleven ingredients are fully disclosed on the label — a level of transparency that remains rare in this category.

The formula is built around three vascular precursors: 6 g of citrulline malate 2:1, 2 g of arginine and 500 mg of PerforMelon® (an extract of Citrullus lanatus, watermelon, a natural source of citrulline). Alongside these sit 3.2 g of beta-alanine, 1 g of taurine, 1 g of L-tyrosine obtained by vegan fermentation, 600 mg of VitaCholine®, 300 mg of sea salt, the patented vitamin C PureWay-C® and vitamin B3.

The flavours on offer: Strawberry Mango, Candy Bubblegum, Ultra Energy, Tropical Punch, Pineapple Crush and Blue Razz Bon Bons. The product joins our caffeine-free booster and Naughty Boy ranges.

What does a 16 g dose contain?

Two figures are missing: the energy value is not declared, and neither is the net weight of the tub — which makes it impossible to state the number of doses. BioPerine® is the only ingredient with no published dosage.

One formulation detail deserves to be flagged, because it genuinely sets this product apart: the vitamin B3 here is nicotinamide, not nicotinic acid. It is the form that does not cause the flush — the facial redness and sensation of heat that some pre-workouts trigger. At 40 mg you will get no skin reaction of that kind. The tingling you do feel will come from the 3.2 g of beta-alanine, and from nothing else.

The authorised wordings that apply are as follows: vitamin C contributes to normal energy-yielding metabolism, to the reduction of tiredness and fatigue and to the protection of cells from oxidative stress; niacin contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue; choline contributes to normal lipid metabolism, the 600 mg comfortably exceeding the 82.5 mg threshold required. For citrulline, arginine, beta-alanine, taurine, tyrosine and watermelon extract, no claim is authorised in Europe.

How should Naughty Boy PUMP be dosed?

Dose: 1 scoop of 16 g, without exceeding the recommended dose. Liquid: 200 to 250 ml of cold water. Timing: 15 to 20 minutes before the session. Frequency: one serving per training day. Duration: the manufacturer imposes neither cycling nor breaks, which is consistent with a stimulant-free formula.

The first time, take a half dose to gauge your tolerance, particularly to the beta-alanine tingling. The powder is fine and mixes without lumps; shake it well.

Three uses stand out depending on the time of day. In the morning, a serving on waking with a light breakfast. In the evening, this is the product's main strength: with no caffeine, it does not disturb sleep. And on long sessions, beyond 90 minutes, there is no stimulant crash to fear towards the end of training.

Hydrate properly during the session. The product can be combined with creatine, BCAAs or a protein in the same routine. What you should avoid is adding another source of arginine or citrulline: you would be stacking with no benefit.

Who is this pre-workout for, and who is it not for?

It targets three situations. End-of-day sessions, where caffeine costs you a night's sleep. People sensitive to stimulants, who have given up on conventional pre-workouts. And long training sessions, where you want the pump without the nervous spike at the start.

The restrictions are clear-cut. Do not use during pregnancy, while breastfeeding, or if you are sensitive to any of the ingredients. Not recommended for under-18s. Consult a healthcare professional before use if you have a medical condition. Do not exceed the recommended dose.

Two specific points. The product is manufactured in a facility that also handles NUTS, MILK, GLUTEN, EGGS, SOYA, CRUSTACEANS and PEANUTS: traces are possible. And depending on the flavour, the formula contains the colours azorubine (E122), tartrazine (E102) or brilliant blue (E133); for the first two, European regulations require the statement may have an adverse effect on activity and attention in children.

What you should not expect from it: energy. That is the most common misunderstanding about this type of product. With no caffeine, there is no kick and no heightened alertness. You will feel a sensation of full muscles, nothing more. And that sensation is not a result: it is neither strength nor muscle gained.

Naughty Boy PUMP or a stimulant pre-workout?

These two products do not replace one another. The question to settle is a simple one: what is it that you are missing before the session?

A stimulant pre-workout from the boosters range is the right choice if what you are missing is the will to get going. A 6:00 morning session, a heavy end to the week, a short night: only caffeine acts on that, and no amount of citrulline will replace it. These formulas typically deliver 200 to 400 mg of caffeine, often with citrulline dosages comparable to the ones here.

Naughty Boy PUMP wins on three fronts. Timing first: it is the only type of product you can take at 20:00. Frequency next, since there is no stimulant tolerance to manage and no cycles to observe. And the sophistication of the formula: 2 g of arginine on top of the citrulline, 600 mg of choline, a patented vitamin C and, above all, nicotinamide rather than nicotinic acid, which avoids the flush. Many of our customers keep both tubs and alternate according to the time of the session — that is probably the most sensible approach.

Frequently asked questions

Is there really zero caffeine?

Yes. The formula contains neither caffeine nor any other stimulant, and that is its whole purpose. Taking it at 20:00 before a 20:30 session will have no consequences for falling asleep.

How many doses are in a tub?

The net weight does not appear in the data supplied by the manufacturer, so we cannot work it out. Divide the weight shown on the packaging by 16 g to get the number of servings.

Is the tingling normal?

Yes, it comes from the 3.2 g of beta-alanine and appears within a quarter of an hour of taking it, on the face and forearms. It lasts around half an hour and fades with regular use. You will not, however, get facial redness: the vitamin B3 used here is nicotinamide, the form that does not cause a flush.

What is PerforMelon®?

A patented extract of Citrullus lanatus, that is to say watermelon, present at 500 mg. Watermelon is a natural source of citrulline, hence its presence alongside the 6 g of citrulline malate. No health claim is authorised in Europe for this extract.

Can it be combined with a creatine or a whey?

Yes, without any difficulty, and the manufacturer says as much. Just avoid adding another product containing arginine or citrulline: stacking brings nothing and you would be paying twice for the same active.

Which colour do the flavours contain?

Depending on the flavour, the formula contains azorubine (E122), tartrazine (E102) or brilliant blue (E133). The first two require the regulatory statement about activity and attention in children. Check the label of the flavour you choose if this matters to you.

Is it suitable for long sessions?

That is in fact one of its best use cases. On a session longer than 90 minutes, a stimulant product drops off before the end of the workout; here, there is nothing to drop off. Drink enough during the effort.

Where to buy Naughty Boy PUMP?

The flavours can be ordered from this page, and we ship throughout France and Europe. It is one of the few stimulant-free pre-workouts whose label gives figures for eleven ingredients: on that specific point, it stands comparison with far more expensive products.

Our Vendargues shop, about ten minutes from Montpellier, keeps the flavours in stock. If you train in the evening and have never tried a caffeine-free formula, this is the product to start with. The full range can be browsed from sports nutrition.

What is ESN's Crank Pump Pro 2.0?

ESN Crank Pump Pro 2.0 is a pre-workout that is caffeine-free and free of any stimulant, developed by the German brand ESN. The daily serving is 30 g, or two scoops — a bulky format explained by the sheer quantity of actives genuinely present.

The formula combines three families. Nitric oxide precursors first, with 10 g of citrulline malate. Cell hydration agents next: HydroPrime® glycerol and coconut water powder. Then a series of supporting actives: L-carnitine L-tartrate, taurine, L-tyrosine, L-glutathione, CitraPeak® glucosyl hesperidin, pine bark extract, AstraGin® and black pepper extract. On top of that come two B vitamins and four quantified minerals, which is unusual in this category.

The flavours on offer: Blue Raspberry, Peach Iced Tea and Tropical Punch. The product joins our caffeine-free booster and ESN France aisles.

What is in a 30 g serving?

The manufacturer publishes neither an energy value, nor a macronutrient breakdown, nor a number of servings per tub: we are flagging that rather than estimating it. Divide the net weight shown on the packaging by 30 to work out the number of servings.

The striking figure is the 10 g of citrulline malate, of which 6.8 g is pure citrulline. That is among the highest dosages on the market: most pre-workouts sit between 1 and 4 g, and few go beyond 6 g of effective citrulline. It also explains the 30 g serving — there is no way of fitting all of that into a 10 g scoop.

The second differentiating point is the minerals. Many so-called “pump” formulas contain none at all; this one delivers 400 mg of sodium, 354 mg of potassium, 120 mg of calcium and 60 mg of magnesium. Those amounts allow the following authorised wordings to be applied: potassium, calcium and magnesium contribute to normal muscle function, magnesium contributes to a reduction of tiredness and fatigue and to normal electrolyte balance, niacin and vitamin B6 contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. For citrulline, glycerol, carnitine, taurine, tyrosine, glutathione, hesperidin, pine bark and AstraGin®, no claim is authorised in Europe.

How do you prepare Crank Pump Pro 2.0?

Serving: 30 g, or 2 scoops. Liquid: around 500 ml of cold water. Timing: 30 to 45 minutes before your session. Frequency: one serving per training day, without exceeding the recommended daily dose. Duration: the manufacturer imposes neither cycling nor breaks, which is consistent with a stimulant-free formula.

The 500 ml are not a detail. With 30 g of powder, including 10 g of citrulline malate which brings a pronounced acidity, too little dilution gives you a harsh drink that is hard to finish. And the glycerol works by holding water: the volume is part of the formula, not just of the taste.

The complete absence of caffeine changes the way this product is used. You can take it at 20:00 before a late session with no consequences for your night's sleep, which is impossible with any booster in the boosters aisle. That is the main reason we recommend it.

Who is this booster for, and who is it not for?

The product is aimed, in the manufacturer's own terms, at adults engaged in intense physical exercise. Three profiles will find themselves in it: those who train late, those who cannot tolerate stimulants, and those looking for the highest citrulline dosages available.

The restrictions are shorter than on a stimulant product. This is a food supplement with sweeteners intended for adults: do not exceed the recommended daily dose, keep out of the reach of children in a cool, dry place. On allergens, the product may contain traces of MILK, SOYA, GLUTEN and EGG owing to the factory's processes. As with any supplement, ongoing medical treatment warrants the advice of your doctor or pharmacist before use.

What you should not expect from it: energy. That is the most common misunderstanding about this category. With no caffeine, there is no kick, no heightened alertness, no start-of-session euphoria. What you will feel is a sensation of fuller muscles — no more strength, no more motivation. Nor should you expect the 1,000 mg of L-carnitine to have an effect on body composition: no claim authorises it, and the dosage would not allow for it.

Crank Pump Pro 2.0 or citrulline bought on its own?

That is the most honest comparison to make here, because citrulline alone accounts for a third of the weight of the serving.

Buying pure citrulline powder is the better choice if budget is what decides. Per gram, plain citrulline costs markedly less than a formulated complex, and you can adjust your dose to the gram — 6 g, 8 g, whatever you want. You also choose between citrulline malate and pure citrulline, something the formula decides for you here. The downside: it is bitter, you have to weigh it out, and you get neither glycerol, nor minerals, nor the supporting actives.

Crank Pump Pro 2.0 wins on what citrulline on its own does not do. The 1.5 g of glycerol and the four quantified minerals change the drink: it is no longer just a nitric oxide precursor, it is also a hydration drink, which brings it close in some respects to the electrolytes aisle. The formula is flavoured, fully quantified on the label, and ready to use. For anyone who does not want to play chemist every morning, it is the right compromise. Note that taurine and L-arginine are also available as isolated powders if you want to top up separately.

Frequently asked questions

Why is the serving 30 g?

Because the formula really does contain what it says it does. Ten grams of citrulline malate on their own take up a third of the serving; add 2.3 g of glycerol, 1.5 g of carnitine tartrate, the taurine, the tyrosine and the minerals, and you naturally arrive at that volume. A 10 g scoop could not hold them.

How many servings in a tub?

The net weight is not in the data supplied by the manufacturer, so we cannot calculate it. Divide the weight shown on the packaging by 30 g to get the number of servings.

Can you take it in the evening?

Yes, without reservation, and that is its main appeal. The formula contains no caffeine and no other stimulant: taking it at 20:00 before a 20:45 session will have no effect on how you fall asleep.

What is the difference between citrulline malate and pure citrulline?

Citrulline malate pairs citrulline with malic acid. On this label, 10 g of citrulline malate corresponds to 6.8 g of effective citrulline: the rest is malate. It is an essential distinction when comparing two products, and ESN deserves credit for publishing both values, which many brands do not.

Are the minerals enough to replace an electrolyte drink?

For a gym session, the 400 mg of sodium and 354 mg of potassium provide a genuine base. For a long endurance outing or in high heat, a dedicated drink remains more suitable: it also provides carbohydrates, which this formula does not.

Does the product contain allergens?

No allergen is present in the recipe, but the manufacturer flags possible traces of milk, soya, gluten and egg linked to the factory's processes. If you have a severe allergy, take that into account.

Which flavour should you choose?

Peach Iced Tea is the mildest and Blue Raspberry the sharpest. At 30 g in 500 ml, the drink stays pronounced: if the acidity bothers you, go up to 600 ml — it changes nothing about the dosages you swallow.

Where can you buy the ESN Crank Pump Pro 2.0?

The flavours can be ordered from this page, and we ship throughout France and Europe. ESN is a German brand whose labels we appreciate on one specific point: they detail everything, including the share of effective citrulline within the malate. That is not so common.

If you are passing through Vendargues, about ten minutes from Montpellier, ask to compare this label with that of a conventional booster: the gap in citrulline dosage is visible to the naked eye, and it explains the difference in price.

Qu'est-ce que l'EVP AQ ?

L'EVP AQ est le glycérol liquide d'Evogen, la marque de Hany Rambod. Ce n'est pas un avant-séance complet : c'est un concentré liquide à ajouter à votre préparation habituelle, ou à boire seul.

Une dose de 30 ml, soit deux cuillères à soupe, apporte 20 g de glycérol végétal GlycoSpan™, 2,5 g de bétaïne, 250 mg de vitamine C et 50 mg du mélange végétal S7™. La bouteille de 473 ml couvre 16 doses complètes, ou 32 demi-doses.

La vitamine C contribue au maintien du fonctionnement normal du système immunitaire pendant et après un exercice physique intense. L'effet bénéfique est obtenu par la consommation journalière de 200 mg de vitamine C en complément de l'apport journalier recommandé : une dose de 250 mg couvre cette condition.

À quoi sert le glycérol dans une séance ?

Le glycérol est une molécule qui retient l'eau. Consommé avec un volume de liquide suffisant, il augmente la quantité d'eau retenue dans l'organisme — c'est le principe de l'hyperhydratation, utilisé de longue date dans les sports d'endurance en conditions chaudes.

En salle, c'est la raison pour laquelle on le retrouve dans les formules dites « pump » : un muscle mieux hydraté est un muscle plus volumineux à l'effort. C'est aussi pourquoi l'EVP AQ se combine naturellement avec une formule à base de citrulline, qui agit sur un mécanisme différent, celui de l'afflux sanguin.

Nous avons consacré un article complet au sujet : le glycérol, hyperhydratation et performance, qui détaille le mécanisme et le protocole de prise.

Questions fréquentes

L'EVP AQ remplace-t-il un pre-workout ?

Non, et ce n'est pas son rôle. Il n'apporte aucun stimulant et ne travaille pas sur la vigilance : c'est un concentré de glycérol à ajouter à une formule existante, ou à prendre seul si vous cherchez uniquement l'effet d'hydratation.

Contient-il de la caféine ?

Aucune caféine ajoutée. Le mélange S7™, dosé à 50 mg au total pour sept ingrédients végétaux, comprend de l'extrait de café vert et de thé vert en quantités minimes. C'est donc un produit qui convient aux séances tardives et qui n'entre pas dans votre total de stimulants de la journée.

Qu'est-ce que la bétaïne ?

Un dérivé d'acide aminé présent naturellement dans la betterave, dosé ici à 2,5 g par dose complète. On la retrouve couramment dans les formules d'avant-séance.

Qu'est-ce que le mélange S7™ ?

Un mélange végétal sous licence, dosé à 50 mg, qui réunit sept extraits : café vert, thé vert, curcuma, cerise acidulée, myrtille, brocoli et chou kale. Comme pour tout ingrédient nommé sur l'étiquette, l'intérêt est de savoir exactement ce qui a été utilisé.

Faut-il boire plus d'eau avec ?

Oui, c'est la condition même de son fonctionnement. Le glycérol retient l'eau que vous lui donnez : sans apport hydrique franc autour de la prise, il n'y a rien à retenir.

Puis-je l'utiliser si je suis licencié en fédération ?

Le statut du glycérol a évolué au fil des années dans les règlements antidopage. Si vous êtes soumis aux contrôles, vérifiez chaque ingrédient auprès de votre fédération et référez-vous à la liste en vigueur de l'AFLD avant d'en consommer.

Où acheter l'EVP AQ ?

Vous pouvez le commander sur cette page, et nous expédions partout en France et en Europe. Cette référence est tenue en stock à l'entrepôt et n'est pas présentée en rayon à Vendargues : si vous souhaitez la voir en boutique, dites-le-nous à l'avance et nous la faisons venir.

Qu'est-ce que The Pump ?

The Pump est l'avant-séance sans stimulant de Conteh Sports. Aucune caféine, aucun stimulant du système nerveux : tout le travail est fait par des vasodilatateurs et des précurseurs d'oxyde nitrique.

Une dosette de 13,8 g apporte 4 000 mg de L-citrulline, 3 000 mg de taurine, 2 000 mg de bétaïne anhydre et 1 000 mg d'extrait de betterave, complétés par de l'extrait de melon amer, du sel rose de l'Himalaya, de l'extrait de pépin de raisin titré à 95 % en proanthocyanidines et 5 mg de BioPerine®.

Chaque ligne est chiffrée sur l'étiquette : il n'y a pas de mélange propriétaire sur cette formule. Le pot de 414 g couvre 30 dosettes.

À qui s'adresse une formule sans stimulant ?

À trois situations très concrètes, et elles concernent plus de monde qu'on ne le pense.

Les séances du soir. La demi-vie de la caféine tourne autour de cinq heures : 300 mg pris à 19 h en laissent encore l'équivalent de 150 mg à minuit, et le sommeil s'en ressent même quand on s'endort sans difficulté. Une formule sans stimulant règle la question.

La sensibilité aux stimulants. Nervosité, cœur qui s'emballe, inconfort digestif : certains ne supportent pas les doses élevées de caféine, et se privent de tout avant-séance pour cette raison.

Le cumul. Si vous buvez déjà du café dans la journée, The Pump n'ajoute rien à votre total. C'est aussi ce qui permet de le combiner librement, y compris avec un produit caféiné pris par ailleurs.

Notre rayon booster sans caféine regroupe les autres formules de ce type, et notre rayon boosters explique comment se construit un avant-séance.

Que font les ingrédients principaux ?

La L-citrulline est le substrat de la production d'oxyde nitrique : c'est l'ingrédient de référence des formules pump, et 4 000 mg par dosette est un dosage franc.

L'extrait de betterave apporte des nitrates, qui empruntent une voie différente pour arriver au même endroit. Associer les deux est une logique de formulation courante et cohérente.

La bétaïne et la taurine sont deux composés qu'on retrouve couramment dans les avant-séance, ici à 2 000 et 3 000 mg. Le BioPerine®, extrait de poivre noir sous licence, ferme la formule à 5 mg.

Le sel rose de l'Himalaya, à 350 mg, apporte du sodium — un choix logique sur une formule destinée à être bue avant un effort.

Questions fréquentes

Contient-il de la caféine ?

Aucune, et c'est sa raison d'être. La formule ne contient aucun stimulant du système nerveux : elle convient aux séances du soir et n'entre pas dans votre total de caféine de la journée.

Quelle différence avec le Mega Pump Elite ?

Les deux sont sans stimulant, mais le Mega Pump Elite est la formule la plus complète de la ligne : dosette plus lourde, davantage de citrulline, du glycérol et de quoi travailler la concentration. The Pump est la version resserrée, centrée sur l'afflux sanguin.

Peut-on l'ajouter à un avant-séance caféiné ?

Oui, sans rien additionner côté stimulants. C'est l'un des usages de ce type de formule : garder sa dose de caféine habituelle et renforcer la partie vasculaire.

Pourquoi du sel dans un avant-séance ?

Le sel rose de l'Himalaya apporte du sodium, à hauteur de 350 mg par dosette. C'est un choix de formulation courant sur une boisson prise avant l'effort.

Y a-t-il des allergènes ?

La formule elle-même n'en contient pas, mais elle est fabriquée dans un atelier qui traite plusieurs allergènes. Le détail figure dans l'onglet Ingrédients.

La gamme complète de la marque est sur notre page Conteh Sports.

Qu'est-ce que le Mega Pump Elite ?

Le Mega Pump Elite est la formule la plus complète de la ligne avant-séance de Conteh Sports, et elle est sans stimulant. Aucune caféine : tout passe par le travail vasculaire et par les ingrédients de la concentration.

Une dosette de 19,5 g apporte 5 000 mg de L-citrulline, 3 000 mg de glycérol GlycerSize™, 3 000 mg de L-tyrosine, 1 500 mg d'acétyl-L-carnitine, 1 000 mg de RedNite® — un extrait de betterave sous licence —, 1 000 mg de L-ornithine, 600 mg de VitaCholine®, 500 mg d'extrait de pépin de raisin et 500 mg de sel rose de l'Himalaya.

Chaque ligne est chiffrée : aucun mélange propriétaire. Le pot de 390 g couvre 20 dosettes.

Trois mécanismes dans une seule dosette

C'est ce qui distingue cette formule d'un produit pump classique : elle travaille sur trois registres à la fois.

L'afflux sanguin, d'abord, avec 5 000 mg de L-citrulline et le RedNite®, un extrait de betterave sous licence qui apporte des nitrates par une voie différente.

L'hydratation intramusculaire, ensuite, avec 3 000 mg de glycérol GlycerSize™. Le glycérol retient l'eau : c'est le mécanisme de l'hyperhydratation, et c'est ce qui donne du volume au muscle à l'effort. Notre article sur le glycérol, hyperhydratation et performance détaille le sujet.

La concentration, enfin, avec 3 000 mg de L-tyrosine et 600 mg de VitaCholine®, une choline sous licence. C'est la partie qu'on ne trouve pas sur un pump simple, et c'est elle qui remplace, en partie, ce qu'on attend habituellement d'une formule caféinée.

Sans caféine, mais pas sans effet

C'est le point qui demande d'être dit clairement : un avant-séance sans stimulant ne « fait rien sentir » de la même manière qu'une formule à 300 mg de caféine. La sensation est différente, pas absente — congestion, volume, et une vigilance qui ne vient pas d'un coup de fouet.

En échange, il se prend à n'importe quelle heure, y compris pour une séance à 21 h, sans toucher au sommeil et sans entrer dans votre total de caféine de la journée. Pour beaucoup de pratiquants qui s'entraînent après le travail, c'est le seul moyen d'avoir un avant-séance qui fonctionne.

Notre rayon booster sans caféine regroupe les autres formules de ce type.

Questions fréquentes

Contient-il de la caféine ?

Aucune. C'est une formule sans stimulant, qui convient aux séances du soir et n'entre pas dans votre total de caféine de la journée.

Quelle différence avec The Pump ?

Le Mega Pump Elite est la version la plus complète : dosette de 19,5 g contre 13,8 g, 5 000 mg de citrulline contre 4 000, et surtout deux ajouts que The Pump n'a pas — le glycérol GlycerSize™ pour l'hydratation intramusculaire, et la L-tyrosine avec la VitaCholine® pour la concentration.

Qu'est-ce que le GlycerSize™ ?

Une forme de glycérol sous licence, dosée ici à 3 000 mg. Le glycérol retient l'eau dans l'organisme, ce qui augmente l'hydratation intramusculaire. Il demande d'être accompagné d'un volume d'eau suffisant pour fonctionner.

Qu'est-ce que le RedNite® ?

Un extrait de betterave sous licence, dosé à 1 000 mg, qui apporte des nitrates. Comme pour tout ingrédient nommé sur l'étiquette, l'intérêt est de savoir exactement quelle matière première a été utilisée.

Peut-on l'ajouter à un avant-séance caféiné ?

Oui. Ne contenant aucun stimulant, il n'additionne rien : certains gardent leur formule caféinée habituelle et ajoutent celle-ci pour la partie vasculaire et le glycérol.

Faut-il boire plus d'eau avec ?

Oui, c'est la condition de fonctionnement du glycérol : il retient l'eau que vous lui donnez. Les 200 à 300 ml de préparation sont un minimum, à compléter sur la séance.

Qu'est-ce que le Pump Shot de 5% Nutrition ?

Le Pump Shot est un shot de congestion prêt à boire, vendu en flacon de 59 ml et parfumé Tropical Punch. Aucun stimulant dans la formule : rien qui accélère le cœur, rien qui tape sur le système nerveux. Tout l'effort du produit porte sur un seul point, remplir le muscle pendant la séance. Le reste de la marque se parcourt dans notre rayon 5% Nutrition.

5% Nutrition a été fondée par Rich Piana, culturiste devenu une figure du milieu autant pour son franc-parler que pour sa masse. Le « 5% » du nom renvoie à sa devise : les cinq pour cent qui font réellement ce qu'il faut, quand les autres se contentent d'en parler. Le Pump Shot applique cette logique à la lettre, avec deux actifs, aucun remplissage et des dosages qui ne cherchent pas à ménager.

Ce qu'il y a dans le Pump Shot

Vingt grammes de glycérol par flacon, soit vingt mille milligrammes. C'est le chiffre qui fait exister ce produit. Le glycérol est un osmolyte : il attire l'eau et la retient dans les tissus, le muscle compris. Plus d'eau dans la fibre, c'est un muscle plus plein, plus dur sous la main, et une congestion qui tient pendant tout le travail.

Ce dosage est inatteignable en poudre. Les formules sèches de cette catégorie travaillent avec du glycérol titré à 65 % et dosé entre un et trois grammes, ce qui laisse très peu de glycérol réel une fois le calcul fait. Le format liquide supprime la contrainte de volume et laisse passer la dose entière.

À côté, cinquante milligrammes de S7, un mélange breveté de sept extraits végétaux : café vert, thé vert, curcuma, cerise acidulée, myrtille, brocoli et chou kale. Le fabricant le présente comme un soutien de la production naturelle d'oxyde nitrique. L'oxyde nitrique détend la paroi des vaisseaux, le sang circule plus librement, et le muscle se remplit davantage série après série. Cinquante milligrammes, c'est le dosage retenu sur l'étiquette.

À qui s'adresse le Pump Shot ?

Aux pratiquants qui veulent la congestion sans la stimulation. À ceux qui s'entraînent tard le soir et préfèrent garder leur nuit. À ceux qui utilisent déjà une formule chargée en caféine et veulent renforcer la congestion sans en rajouter une couche.

C'est aussi un produit de déplacement : le flacon se glisse dans un sac de sport, s'ouvre sur place et se boit tel quel. Pas de shaker à transporter, pas de poudre à doser, pas de grumeaux. Sur un jour de bras ou de dos, quand on veut voir le muscle se remplir série après série, c'est exactement le genre d'outil qu'on cherche.

Questions fréquentes

Qu'est-ce que la congestion en musculation ?

C'est l'afflux de sang et d'eau dans le muscle pendant l'effort. Le muscle gonfle, la peau se tend, les veines ressortent. Le phénomène est mecanique : les séries longues ouvrent la circulation locale et le muscle se remplit.

Comment avoir une bonne congestion musculaire ?

Trois leviers jouent ensemble : des séries longues avec des temps de repos courts, une hydratation correcte, et des actifs qui tirent l'eau dans le muscle. Le glycérol agit sur ce troisième levier, et c'est tout ce que fait le Pump Shot.

Combien de temps dure la congestion musculaire ?

Elle tient en général de trente minutes à deux heures après la séance, selon le volume de travail et l'état d'hydratation. Elle redescend ensuite d'elle-même, sans rien laisser.

Le Pump Shot contient-il de la caféine ?

Non, la formule est construite sans stimulant. C'est son positionnement : elle travaille sur la circulation et sur le volume d'eau intramusculaire, pas sur le système nerveux.

Qu'est-ce que le S7 ?

Un mélange breveté de sept extraits végétaux : café vert, thé vert, curcuma, cerise acidulée, myrtille, brocoli et chou kale. Le fabricant le dose à 50 mg et le présente comme un soutien de la production naturelle d'oxyde nitrique.

Pourquoi un shot liquide plutôt qu'une poudre ?

Parce que vingt grammes de glycérol ne tiennent pas dans une dosette. Le liquide lève la contrainte de volume, permet le dosage complet, et il n'y a rien à dissoudre ni à secouer.

Quel goût a le Pump Shot ?

Tropical Punch, un fruité franc et sucré. Le flacon se vide en une gorgée et l'arrière-goût reste court.
