Mutant

What is Mutant Mass?

Mutant Mass is a gainer, that is to say a powder whose main purpose is not protein but calories. One 280 g dose, i.e. four scoops, provides 1,100 kcal. The formula is predominantly carbohydrate: the first ingredient on the list is a blend of waxy maize starch, maltodextrin, barley starch, sweet potato and rolled oats.

Next comes the brand's protein matrix, which brings together six dairy fractions: whey protein concentrate, hydrolysate and isolate, micellar casein, milk protein concentrate and isolate. A lipid blend completes the whole (fractionated MCT coconut oil, avocado, flaxseed, pumpkin seed, sunflower oil), along with cocoa, flavourings, a caramel colour, salt, sucralose, sunflower lecithin, enzymes and a Cinnulin PF® cinnamon extract. The flavours listed: Vanille Ice Cream, Cookies & Cream, Banana n Strawberry, Triple Chocolat and Fudge Brownie. The rest of the range is in the Mutant Nutrition collection, and the competing formulas in our hard gainer aisle.

What does a 280 g dose of Mutant Mass contain?

The manufacturer's declaration, brought back to the useful references: the 280 g dose and the regulatory 100 g.

* Values recalculated from the declaration per 280 g dose, the only reference published by the manufacturer. Salt is obtained by the regulatory conversion salt = sodium x 2.5. ** No nutrient reference value is established for these nutrients. Three pieces of data are missing from the declaration in our possession and we will not invent them: saturates, fibre, and the full amino acid profile beyond the BCAAs and glutamine. The weight of the tub and the number of doses it contains are not in our data either: refer to the packaging to work out how long it will last you.

Two ingredients call for clarification. The enzymes (lactase, protease) appear on the list; we attribute no digestive effect to them, as no claim of that kind is authorised in Europe. Cinnulin PF® is a cinnamon extract: present, quantity not declared, no property ascribed to it. Protein, for its part, contributes to a growth in muscle mass and to the maintenance of muscle mass, and 56 g per dose is a substantial intake.

How should you take Mutant Mass?

• Dose: 280 g, i.e. 4 scoops, for the full dose. The half dose is 2 scoops.
• Volume of liquid: 500 to 700 ml of cold water or skimmed milk. Below 500 ml, the mixture becomes hard to swallow.
• Timing: full dose within the 30 minutes following the session, half dose as a snack between two meals. Avoid the two hours before a meal, or you will no longer be hungry when it is time to eat.
• Frequency: 2 servings a day at most, never exceeding 2 full doses.
• Duration: the manufacturer sets no length of course. A gainer is used for the time a weight-gain phase lasts, not permanently.

Build up gradually: it is the most important instruction on this page. The manufacturer recommends 2 scoops a day in the first week, 3 in the second, and the full dose only from the third onwards. Going straight in at 280 g and 192 g of carbohydrate is the surest way to give up on the tub. A 700 ml shaker or a blender is necessary; a 500 ml shaker is not enough, and our accessories cover that size.

The dosage, the timing and the composition are covered in detail in our dedicated article: Mutant Mass: dosage, timing and composition. This page describes the product, the article describes the method.

Who is Mutant Mass for, and who is it not for?

It is aimed at people who cannot manage to eat enough to gain weight and who have already tried increasing their meals. Drinking 1,100 kcal is easier than chewing them: that is the whole point of the product, and its only justification.

It is not for you if you gain weight easily. At 1,100 kcal a dose, a poorly controlled surplus turns into fat mass, not muscle. In that case, a whey and carbohydrates measured out separately will give you far better control.

Nor is it suitable in the event of an allergy to milk or soya, both declared as allergens. One point deserves your attention: the ingredient list includes barley starch and rolled oats, two cereals affected by gluten, and the label mentions gluten among the possible traces. If you have coeliac disease, this product is not for you. The manufacturer advises against it for the under-18s and for pregnant or breastfeeding women. If you are on any treatment, if you are diabetic or if you have any doubt, speak to your doctor or your pharmacist: 192 g of carbohydrate in a single serving is not trivial.

What you should not expect from it: a gainer does not build muscle in place of training and does not make up for food being absent for the rest of the day.

Mutant Mass or whey and carbohydrates separately?

The comparison does not systematically go in the gainer's favour.

Mutant Mass wins on simplicity. A single powder, a single shaker, a carbohydrate-to-protein ratio already settled at 192 to 56. When the problem is not managing to eat, reducing the number of decisions is a real advantage.

The formula you put together yourself wins on control and on cost. A whey concentrate combined with maltodextrin lets you adjust the protein share and the carbohydrate share independently, week after week, according to what the scales say. It is the right option if you are putting on fat too fast, or if you want to bring the calories down without touching the protein.

Between the two, a lean gainer offers a less carbohydrate-heavy ratio, for a more measured surplus. Whatever the choice, creatine monohydrate is managed separately.

Frequently asked questions

Do you really have to take 4 scoops at once?

No, and it is not advised at the start. The manufacturer's protocol begins at 2 scoops a day in the first week and only reaches the full dose in the third. Staying at 2 or 3 scoops for the long run is still a considerable calorie intake.

Can it be mixed with milk rather than water?

Yes, the manufacturer mentions skimmed milk. You are then adding the calories and carbohydrates of the milk to those of the product, which pushes a full dose well beyond 1,100 kcal. With water, you know exactly what you are drinking.

How many doses does a tub contain?

We cannot tell you: the weight of the tub is not in the data available to us. Divide the weight shown on the packaging by 280 g to get the number of full doses.

Does Mutant Mass contain gluten?

The recipe contains barley starch and rolled oats, and the label flags gluten among the possible traces. It is not a gluten-free product and it is not suitable in the event of coeliac disease.

Which flavour should you choose for everyday use?

Over two servings a day for several weeks, the less sweet profiles such as Vanille Ice Cream generally become tiresome less quickly than the intense chocolates. The flavours listed are set out at the top of this page.

Do the 11 g of BCAAs replace a BCAA supplement?

They are naturally present in the dairy proteins of the formula, they are not added. If your daily protein intake is covered, a BCAA supplement on top has no demonstrated usefulness.

Can it be taken on days without training?

Yes. The calorie surplus is played out over the whole week, not only on session days. Many people then split the product into two half doses between meals rather than a single serving.

Where can you buy Mutant Mass?

Mutant Mass is available on this page in the flavours listed above the add-to-basket button, and in our Vendargues shop, about ten minutes from Montpellier. It is a product that is better discussed before buying: the question is almost never "which flavour" but "do you really need a gainer", and that conversation takes three minutes at the counter.

We ship throughout France and Europe. The rest of the mass gain aisle lets you compare the ratios before making up your mind.

What is Mutant Mass 6800 g?

Mutant Mass is a gainer, that is to say a powder designed to add a lot of calories to your day without having to eat more. One 280 g serving — four scoops — provides 1 100 kcal, 56 g of protein, 192 g of carbohydrate and 12 g of fat. The 6.8 kg bag covers 24 full servings.

Mutant is a Canadian brand, and this product is one of its long-standing formats. What sets it apart is the sheer number of sources: six different proteins and five carbohydrate sources, where many gainers make do with a whey concentrate and maltodextrin.

The flavours in the range: Cookies & Cream, Chocolate Fudge Brownie, Triple Chocolate, Vanilla Ice Cream and Strawberry Banana. The rest of the brand can be browsed in our Mutant Nutrition section, and other formulas of the same type in our hard gainer section.

What does a serving of Mutant Mass contain?

1 100 kcal in a shaker is the equivalent of three light meals. That is the reference point that matters, and it should be taken seriously: this is not a protein powder, it is a massive calorie load that you drink. For someone who cannot get past 2 500 kcal a day at the table, it is a formidably effective tool; for someone who already eats properly, it is the fastest way to put on fat.

The 26.1 g of essential amino acids, of which 12.2 g are BCAAs, are not added: they occur naturally in the 56 g of protein. That is an honest clarification the manufacturer makes itself, and it bears repeating, because many brands let you believe they have been added separately. Every milk protein contains these amino acids in these proportions.

The protein blend combines six sources: whey concentrate, isolate and hydrolysate, micellar casein, milk protein concentrate and milk protein isolate. The first three digest quickly, the next three more slowly. It is a coherent build for a product meant to replace a snack, less relevant if you are after a fast post-workout shake — a whey concentrate then does the job better.

On the carbohydrate side, the five sources are waxy maize starch, maltodextrin, barley starch, sweet potato and oat flakes. The first two are fast, the other three slower. A patented cinnamon extract also appears in the formula, along with two enzymes, lactase and protease. Let us note it without crediting it with any effect: no health claim is authorised in Europe for cinnamon extract or for these enzymes. The authorised claim on protein, on the other hand, applies fully here: protein contributes to the maintenance and growth of muscle mass.

How do you take Mutant Mass?

Serving: 4 scoops, that is 280 g. Liquid: 750 ml to 1 litre of cold water. Preparation: shake for 20 to 30 seconds in a shaker, or use a blender. Timing: after your session, or as a snack between two meals. Duration: there is no notion of a course here, it is a food intake.

Start with two scoops, not four. That is the most important piece of advice on this page, and the manufacturer gives it itself. 280 g of powder in one go, for someone who has never taken a gainer, almost always means a heavy stomach, difficult digestion and a skipped next meal — which cancels out the whole point of the product. Two scoops already gives you 550 kcal and 28 g of protein.

The volume of liquid is not negotiable. 750 ml to 1 litre for a full serving: below that, the texture becomes thick to the point of being hard to drink. A blender gives a far better result than a shaker with this kind of powder, and skimmed milk makes the drink creamier than water does, while adding a few calories.

Do not take it just before a meal. That is the mistake that ruins bulking phases: a 1 100 kcal shake an hour before lunch kills your appetite, and you eat less at the table. A gainer should be added to meals, not replace them. Slot it in after your session, or mid-morning and in the afternoon on rest days.

The logical complement, if you are looking to increase your intake without relying entirely on powder, remains food carbohydrates: cream of rice or oat flour are eaten with a spoon and fill you up differently.

Who is Mutant Mass for, and who is it not for?

It is aimed at someone whose real problem is appetite: a fast metabolism, days too busy to eat five times, a long-standing difficulty in putting on weight. In that situation, a gainer is the most effective product on the shelf, quite simply because it is easier to drink 1 100 kcal than to chew them.

It is not suitable for anyone under 18, for pregnant or breastfeeding women, or for anyone on medical treatment without their doctor's advice. It contains milk, soya and gluten (barley and oats): three major allergens, which rules out a fair number of profiles straight away. Traces of egg, crustaceans, fish, nuts and peanuts are also possible.

Nor is it suitable for someone who already eats enough. Adding 1 100 kcal to a balanced diet does not build muscle: it builds fat. A gainer only makes sense if you have measured your intake and found it wanting. Otherwise, a plain whey isolate powder, at 120 kcal a serving, answers your need better.

What you should not expect from it. No gainer builds muscle mass on its own: it supplies calories, and training decides what the body does with them. Without heavy, regular sessions, weight gained on a gainer is essentially fat. And 480 mg of sucralose per serving is an amount you notice in the taste: some people do not get on with it.

Gainer, or protein and carbohydrates separately?

This is the classic trade-off in the mass-gain aisle, and there is no wrong answer — just two different logics.

Buying them separately costs less and leaves you in control. A protein on one side, maltodextrin or oat flakes on the other, and you build the ratio that suits you: more carbohydrate on training days, less on rest days. You can also step it up gradually rather than swallowing a 1 100 kcal block.

The gainer wins on simplicity and on consistency. Four scoops, a litre of water, done. And for someone who struggles to eat, the main constraint is not the price per kilo: it is managing to take in the calories every day, without thinking about it. A product you actually prepare beats a perfect protocol you abandon after ten days.

One middle-ground option is worth knowing about: a lean gainer offers a ratio more favourable to protein and less loaded with carbohydrate, which suits a controlled bulk better than a product with 192 g of carbohydrate per serving. It is often the best compromise for anyone who does not want to pick up three kilos of fat along the way.

Frequently asked questions

How many calories per serving?

1 100 kcal for a 280 g serving, that is four scoops, with 56 g of protein, 192 g of carbohydrate and 12 g of fat. The 6.8 kg bag covers 24 full servings. At a half serving, allow 550 kcal and 28 g of protein.

Do you really need to take four scoops?

No, and we even recommend starting with two. The manufacturer recommends it too. 280 g in one go, when you are not used to it, almost always causes digestive discomfort and kills your appetite for the next meal — the opposite of what you are after.

Are the BCAAs added to the formula?

No. The 26.1 g of essential amino acids and the 12.2 g of BCAAs occur naturally in the 56 g of milk protein. It is the manufacturer itself that makes this clear, and it is more honest than the way many competing brands present it.

What are the allergens?

Milk, soya and gluten, the last of these coming from the barley and oats in the carbohydrate blend. The product is also made on equipment that handles egg, crustaceans, fish, nuts and peanuts: traces are possible.

Which flavours are available?

Cookies & Cream, Chocolate Fudge Brownie, Triple Chocolate, Vanilla Ice Cream and Strawberry Banana. The composition is identical from one flavour to the next. Each contains 480 mg of sucralose per serving, which makes for a very sweet taste.

Water or milk to mix it?

Both work, with 750 ml to 1 litre for a full serving. Milk gives a creamier texture and adds calories, which works in the product's favour. Water remains easier to digest at that sort of volume. A blender gives a better result than a shaker.

Does this product build muscle?

It supplies calories and protein; it is training that determines what the body does with them. Without heavy, regular sessions, the weight you gain will be mostly fat. And if your food intake is already sufficient, adding 1 100 kcal will do you no favours.

Where can you buy Mutant Mass 6800 g?

The 6.8 kg bag can be ordered from this page in the flavours available, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, we always start with the same question before selling a gainer: how much are you actually eating at the moment? Nine times out of ten, the answer points towards two scoops rather than four, and sometimes towards a different product altogether. The rest of our selection can be browsed in the mass gain section.
