The “protein” line corresponds to the free amino acids in the formula, counted here by the manufacturer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e4 g of beta-alanine is at the top end of the market\u003c\/strong\u003e 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 \u003ca href=\"\/en\/collections\/beta-alanine\"\u003ebeta-alanine\u003c\/a\u003e 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.\u003c\/p\u003e\n\u003cp\u003eThe same remark applies to the \u003cstrong\u003e3 g of \u003ca href=\"\/en\/collections\/creatine-1\"\u003ecreatine monohydrate\u003c\/a\u003e\u003c\/strong\u003e. 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.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003e375 mg of magnesium\u003c\/strong\u003e covers 100% of the reference value, and \u003cstrong\u003emagnesium contributes to normal muscle function, to the normal functioning of the nervous system and to the reduction of tiredness and fatigue\u003c\/strong\u003e. 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 \u003ca href=\"\/en\/collections\/magnesium\"\u003emagnesium\u003c\/a\u003e elsewhere, count it in.\u003c\/p\u003e\n\u003cp\u003eThe 3 g of AAKG provides arginine bound to ketoglutarate. The effective arginine content is not published, and \u003cstrong\u003eneither arginine, nor beta-alanine, nor taurine, nor tyrosine holds an authorised claim in Europe\u003c\/strong\u003e. 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.\u003c\/p\u003e\n\n\u003ch4\u003eIngredients list\u003c\/h4\u003e\n\u003cp\u003eBeta-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). \u003cstrong\u003eMay contain traces of GLUTEN, MILK, EGG, SOYA and NUTS.

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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eWho is PreWork NOSTIM for, and who is it not for?\u003c\/h2\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eWhat 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.\u003c\/p\u003e\n\n\u003ch2\u003ePreWork NOSTIM or a caffeinated pre-workout?\u003c\/h2\u003e\n\u003cp\u003eThe difference is clear-cut and comes down to what time you train.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eNOSTIM 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.\u003c\/p\u003e\n\u003cp\u003eThere is a third route if you already take your creatine separately: \u003ca href=\"\/en\/collections\/pre-workout-sans-creatine\"\u003ecreatine-free pre-workouts\u003c\/a\u003e avoid the overlap. And if it is arginine alone that interests you, our \u003ca href=\"\/en\/collections\/l-arginine\"\u003eL-arginine\u003c\/a\u003e section offers it at a serious dose.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhy do I get tingling after taking it?\u003c\/h3\u003e\n\u003cp\u003eThat'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.\u003c\/p\u003e\n\u003ch3\u003eCan you take it in the evening?\u003c\/h3\u003e\n\u003cp\u003eYes, 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.\u003c\/p\u003e\n\u003ch3\u003eShould you take extra creatine?\u003c\/h3\u003e\n\u003cp\u003eIf 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.\u003c\/p\u003e\n\u003ch3\u003eIs 375 mg of magnesium too much for a single serving?\u003c\/h3\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003ch3\u003eHow long before training should you take it?\u003c\/h3\u003e\n\u003cp\u003eThirty 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.\u003c\/p\u003e\n\u003ch3\u003eDo you need to take breaks from it?\u003c\/h3\u003e\n\u003cp\u003eNo, 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.\u003c\/p\u003e\n\u003ch3\u003eDoes the product contain sugar?\u003c\/h3\u003e\n\u003cp\u003eVery 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhere can you buy IO Genix PreWork NOSTIM?\u003c\/h2\u003e\n\u003cp\u003eThe 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.
