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.
| Nutrient | Per 100 g* | Per 280 g dose | % NRV |
|---|---|---|---|
| Energy | 393 kcal* | 1,100 kcal | ** |
| Fat | 4.3 g* | 12 g | ** |
| of which saturates | not disclosed | not disclosed | ** |
| Carbohydrate | 68.6 g* | 192 g | ** |
| of which sugars | 6.4 g* | 18 g | ** |
| Fibre | not disclosed | not disclosed | ** |
| Protein | 20 g* | 56 g | ** |
| Salt | 0.61 g* | 1.7 g* | ** |
| Sodium | 243 mg* | 680 mg | ** |
| BCAAs (leucine, isoleucine, valine) | 3.9 g* | 11 g | ** |
| Naturally occurring L-glutamine | 3.7 g* | 10.4 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.
Qu'est-ce que le Mutant Whey ?
Le Mutant Whey est une protéine en poudre bâtie sur trois protéines de lactosérum : un concentré, un isolat et une protéine hydrolysée. Chacune s'assimile à son rythme, ce qui est tout l'intérêt d'un mélange plutôt que d'une source unique.
Une dose de 38 g apporte 22,4 g de protéines. Sur la poudre sèche, cela représente 59 g de protéines pour 100 g.
Ce que la dose contient exactement
Pour 38 g : 148 kcal, 22,4 g de protéines, 9 g de glucides dont 4 g de sucres, et 2,5 g de lipides dont 1,5 g d'acides gras saturés.
La formule contient aussi des triglycérides à chaîne moyenne issus d'huile de coco, et des enzymes — lactase et protéase — ajoutées par le fabricant.
Les protéines sont d'origine laitière : la poudre convient aux végétariens mais pas aux véganes, et elle contient du lait et du soja.
Les trois formats
Le pot de 908 g couvre environ 24 doses, celui de 2,27 kg environ 60, celui de 4,54 kg environ 119. Cinq goûts : Vanilla Ice Cream, Triple Chocolate, Cookies & Cream, Strawberry Cream et Chocolate Fudge Brownie.
Les autres protéines de la boutique sont dans le rayon whey concentrée.

Who is Mutant Nutrition?
Mutant is a Canadian sports nutrition brand, produced by Fit Foods, a company based in British Columbia that has been manufacturing and distributing several supplement brands since 1996. Mutant is its most internationally recognized line, and by far the one that has made the biggest mark in the mass gain category.
Its positioning is explicit even in the brand's slogan, Leave Humanity Behind: Mutant targets strength and bodybuilding practitioners, emphasizes the raw and bulky nature of its formats, and does not seek to appeal to the general public at the gym. It is an unashamed niche brand, whose visual identity and discourse have remained practically unchanged.
In France, it is not distributed in supermarkets and arrives through specialized retailers. Its recognition here is due to a single product: Mutant Mass, one of the most requested gainers on the market.
What is the value of the Mutant range?
The brand's international catalog covers several product families, but what we stock is focused: the gainer, and only the gainer. This is our choice, not a coincidence, and it corresponds to what actually sells from this brand in France.
In its field, Mutant is strong. Mutant Mass is one of the few gainers whose protein matrix is genuinely multi-source – whey concentrate, isolate, hydrolyzed proteins, micellar casein, milk proteins – and whose carbohydrate component is not limited to cheap maltodextrin: it contains waxy maize starch, oats, sweet potato, and barley starch. The formula also includes lipids from various sources and digestive enzymes, two details that matter for a product consumed in very large quantities.
What the brand does not offer, in our market, is everything else: no standalone protein, no creatine, no boosters, no micronutrition. To build a complete program, you will necessarily need to supplement elsewhere – see our protein section and our mass gain selection.
What are the flagship Mutant products we sell?
Mutant Mass
The brand's iconic gainer, available from us, notably in the large 6.8 kg format. The label's figures explain its reputation: a full dose of four scoops provides approximately 1,100 kilocalories, including 56g of protein, 192g of carbohydrates, and 12g of lipids. This product is designed for those who struggle to eat enough, not for those who simply want to add a shake to their day.
Preparation requires 500 to 700 ml of liquid for a full dose – a volume to keep in mind before ordering. The brand recommends starting with two scoops for the first few days, allowing digestion to adjust, and this advice should be taken seriously: going straight to the full dose is the best way to get disgusted with the product in three days.
We do not detail here the usage protocols, common mistakes, and how to integrate this gainer into a typical day: everything is covered in our article Mutant Mass: 7 tips to maximize your mass gain, which goes much further into practical aspects than a brand page allows.
Our retailer's opinion
What works. Mutant Mass is a true gainer, in the sense that it genuinely solves the problem it claims to solve: getting a thousand calories into someone who has no appetite. The composition is above average for its category, particularly in the variety of carbohydrate sources and the presence of digestive enzymes. The large format also remains one of the cheapest ways to buy powdered calories.
The main limitation, and it's arithmetic: based solely on cost, a gainer is more expensive than the same intake composed by oneself. A dose of Mutant Mass is essentially carbohydrates. Buying whey concentrate and rice cream or oat flour separately, then mixing them in proportions that suit you, is almost always cheaper per kilo and allows you to control the ratio. What you pay for with a gainer is convenience and consistency – which is legitimate, provided you know it.
Three additional caveats. Volume: a full dose represents half a liter to drink, which is difficult to consume multiple times a day and curbs the appetite for the next meal for some – the exact opposite effect of what is desired. Caloric density: this product is made for a dedicated athlete who trains hard and struggles to gain weight; used without this context, it simply causes fat gain. And finally, product range depth: for us, Mutant is limited to the gainer, so brand loyalty is not possible for the rest of the shopping cart.
Mutant or IO Genix for a gainer?
This is the most useful comparison because we sell both, and they don't target the same profile.
IO Genix's Protein Mass is a gainer with a more modest caloric density, less voluminous to prepare, and generally cheaper per kilo. It suits someone who eats properly and wants to add a reasonable caloric supplement. Mutant Mass is more extreme: more calories per dose, more different sources, a true hard gainer product for those who don't gain a gram despite complete meals.
A third option, not to be overlooked: the lean gainer, with fewer carbohydrates, for those who want to limit fat gain. And if you have difficulty digesting large volumes, the simplest solution is to separately add maltodextrin or rice cream to your usual shake, in the dose you choose.
Frequently Asked Questions
Is Mutant a good brand?
For gainer, yes: Mutant Mass is one of the serious benchmarks in its category, with a better-designed composition than average. For the rest, we cannot speak for you, as we do not stock the brand's other products.
What is the best Mutant product?
Mutant Mass, and there's no debate: it's the product that made the brand and the only one we deemed relevant to bring to France. The large 6.8 kg format is the most cost-effective per kilo, provided you are sure you like the flavor – hence the importance of tasting first.
When should Mutant Mass be taken during the day?
The timing matters much less than the total caloric intake for the day, but two guidelines help. Place it between meals or after training, never right before a meal: half a liter of gainer cuts appetite and makes you lose on one side what you gain on the other. And split the dose: two half-doses at two different times are much better than a full dose consumed all at once, especially in the first few weeks. On non-training days, if your appetite allows, a half-dose is usually enough to maintain the surplus.
Does gainer cause bloating?
This is the most frequently reported discomfort with this category, and it almost always comes from the quantity, not the formula: nearly 200g of carbohydrates and 56g of protein at once is a lot for a digestive tract. The remedies are simple – start with two scoops, increase over two to three weeks, split the dose, increase water volume, and drink slowly. The presence of lactose can also play a role in sensitive individuals: prepare it with water rather than milk to check. If the discomfort persists despite everything, the product is not for you, and adjusting your meals will do the same job.
Where to buy Mutant Mass in France?
From specialized sports nutrition retailers, online and in-store. The brand is not present in French supermarkets. We have it in stock and ship throughout France and Europe.
How to recognize authentic Mutant Mass?
Look at the French labeling affixed by the importer, the lot number, and the expiration date. For a heavy and bulky product like a 6.8 kg bag, offers significantly cheaper than the market often hide parallel imports without regulatory labeling, with short dates. We source through the official channel.
Does Mutant Mass cause fat gain?
It causes weight gain, and the distribution between muscle and fat depends entirely on what surrounds it: regular resistance training, sleep, and measured caloric surplus. Used without training, or in addition to an already sufficient diet, it causes fat gain. This is not a product defect; it's its mode of use.
Is a gainer essential for mass gain?
No. A gainer is just a convenient way to achieve a caloric surplus when eating more is difficult. If you can add 400 or 500 kilocalories to your diet with rice, pasta, olive oil, and peanut butter, the result is identical and the cost lower.
Is Mutant Mass suitable for controlled athletes?
We do not claim any third-party anti-doping certification for this range. If you are subject to controls, check the lot status with the manufacturer and refer to the list of prohibited substances published by AFLD rather than the reputation of a brand.
Can it be combined with creatine?
Yes, with no known interaction: creatine monohydrate can be added to the same shaker if that simplifies your life. This is also the most rational combination for mass gain, creatine being the best-documented supplement in the category. In case of known kidney or liver disease, pregnancy, or breastfeeding, consult your doctor before any supplementation.
Where to buy Mutant Mass near Montpellier?
Mutant Mass is in stock at our store in Vendargues, about ten minutes from Montpellier, at 285 rue des Portes Domitiennes. For a bag of this size, two questions are worth asking before buying: do you like the flavor, and do you genuinely need a gainer rather than just an adjustment to your meals? We are happy to answer the latter, even if the answer means selling less.
If you prefer to order online, we ship throughout France and Europe.
Food supplements should be part of a varied and balanced diet and a healthy lifestyle. They do not replace medical advice.

In France, it is not distributed in supermarkets and arrives through specialized retailers. Its recognition here is due to a single product: Mutant Mass, one of the most requested gainers on the market.
What is the value of the Mutant range?
The brand's international catalog covers several product families, but what we stock is focused: the gainer, and only the gainer. This is our choice, not a coincidence, and it corresponds to what actually sells from this brand in France.
In its field, Mutant is strong. Mutant Mass is one of the few gainers whose protein matrix is genuinely multi-source – whey concentrate, isolate, hydrolyzed proteins, micellar casein, milk proteins – and whose carbohydrate component is not limited to cheap maltodextrin: it contains waxy maize starch, oats, sweet potato, and barley starch. The formula also includes lipids from various sources and digestive enzymes, two details that matter for a product consumed in very large quantities.
What the brand does not offer, in our market, is everything else: no standalone protein, no creatine, no boosters, no micronutrition. To build a complete program, you will necessarily need to supplement elsewhere – see our protein section and our mass gain selection.
What are the flagship Mutant products we sell?
Mutant Mass
The brand's iconic gainer, available from us, notably in the large 6.8 kg format. The label's figures explain its reputation: a full dose of four scoops provides approximately 1,100 kilocalories, including 56g of protein, 192g of carbohydrates, and 12g of lipids. This product is designed for those who struggle to eat enough, not for those who simply want to add a shake to their day.
Preparation requires 500 to 700 ml of liquid for a full dose – a volume to keep in mind before ordering. The brand recommends starting with two scoops for the first few days, allowing digestion to adjust, and this advice should be taken seriously: going straight to the full dose is the best way to get disgusted with the product in three days.
We do not detail here the usage protocols, common mistakes, and how to integrate this gainer into a typical day: everything is covered in our article Mutant Mass: 7 tips to maximize your mass gain, which goes much further into practical aspects than a brand page allows.
Our retailer's opinion
What works. Mutant Mass is a true gainer, in the sense that it genuinely solves the problem it claims to solve: getting a thousand calories into someone who has no appetite. The composition is above average for its category, particularly in the variety of carbohydrate sources and the presence of digestive enzymes. The large format also remains one of the cheapest ways to buy powdered calories.
The main limitation, and it's arithmetic: based solely on cost, a gainer is more expensive than the same intake composed by oneself. A dose of Mutant Mass is essentially carbohydrates. Buying whey concentrate and rice cream or oat flour separately, then mixing them in proportions that suit you, is almost always cheaper per kilo and allows you to control the ratio. What you pay for with a gainer is convenience and consistency – which is legitimate, provided you know it.
Three additional caveats. Volume: a full dose represents half a liter to drink, which is difficult to consume multiple times a day and curbs the appetite for the next meal for some – the exact opposite effect of what is desired. Caloric density: this product is made for a dedicated athlete who trains hard and struggles to gain weight; used without this context, it simply causes fat gain. And finally, product range depth: for us, Mutant is limited to the gainer, so brand loyalty is not possible for the rest of the shopping cart.
Mutant or IO Genix for a gainer?
This is the most useful comparison because we sell both, and they don't target the same profile.
IO Genix's Protein Mass is a gainer with a more modest caloric density, less voluminous to prepare, and generally cheaper per kilo. It suits someone who eats properly and wants to add a reasonable caloric supplement. Mutant Mass is more extreme: more calories per dose, more different sources, a true hard gainer product for those who don't gain a gram despite complete meals.
A third option, not to be overlooked: the lean gainer, with fewer carbohydrates, for those who want to limit fat gain. And if you have difficulty digesting large volumes, the simplest solution is to separately add maltodextrin or rice cream to your usual shake, in the dose you choose.
Frequently Asked Questions
Is Mutant a good brand?
For gainer, yes: Mutant Mass is one of the serious benchmarks in its category, with a better-designed composition than average. For the rest, we cannot speak for you, as we do not stock the brand's other products.
What is the best Mutant product?
Mutant Mass, and there's no debate: it's the product that made the brand and the only one we deemed relevant to bring to France. The large 6.8 kg format is the most cost-effective per kilo, provided you are sure you like the flavor – hence the importance of tasting first.
When should Mutant Mass be taken during the day?
The timing matters much less than the total caloric intake for the day, but two guidelines help. Place it between meals or after training, never right before a meal: half a liter of gainer cuts appetite and makes you lose on one side what you gain on the other. And split the dose: two half-doses at two different times are much better than a full dose consumed all at once, especially in the first few weeks. On non-training days, if your appetite allows, a half-dose is usually enough to maintain the surplus.
Does gainer cause bloating?
This is the most frequently reported discomfort with this category, and it almost always comes from the quantity, not the formula: nearly 200g of carbohydrates and 56g of protein at once is a lot for a digestive tract. The remedies are simple – start with two scoops, increase over two to three weeks, split the dose, increase water volume, and drink slowly. The presence of lactose can also play a role in sensitive individuals: prepare it with water rather than milk to check. If the discomfort persists despite everything, the product is not for you, and adjusting your meals will do the same job.
Where to buy Mutant Mass in France?
From specialized sports nutrition retailers, online and in-store. The brand is not present in French supermarkets. We have it in stock and ship throughout France and Europe.
How to recognize authentic Mutant Mass?
Look at the French labeling affixed by the importer, the lot number, and the expiration date. For a heavy and bulky product like a 6.8 kg bag, offers significantly cheaper than the market often hide parallel imports without regulatory labeling, with short dates. We source through the official channel.
Does Mutant Mass cause fat gain?
It causes weight gain, and the distribution between muscle and fat depends entirely on what surrounds it: regular resistance training, sleep, and measured caloric surplus. Used without training, or in addition to an already sufficient diet, it causes fat gain. This is not a product defect; it's its mode of use.
Is a gainer essential for mass gain?
No. A gainer is just a convenient way to achieve a caloric surplus when eating more is difficult. If you can add 400 or 500 kilocalories to your diet with rice, pasta, olive oil, and peanut butter, the result is identical and the cost lower.
Is Mutant Mass suitable for controlled athletes?
We do not claim any third-party anti-doping certification for this range. If you are subject to controls, check the lot status with the manufacturer and refer to the list of prohibited substances published by AFLD rather than the reputation of a brand.
Can it be combined with creatine?
Yes, with no known interaction: creatine monohydrate can be added to the same shaker if that simplifies your life. This is also the most rational combination for mass gain, creatine being the best-documented supplement in the category. In case of known kidney or liver disease, pregnancy, or breastfeeding, consult your doctor before any supplementation.
Where to buy Mutant Mass near Montpellier?
Mutant Mass is in stock at our store in Vendargues, about ten minutes from Montpellier, at 285 rue des Portes Domitiennes. For a bag of this size, two questions are worth asking before buying: do you like the flavor, and do you genuinely need a gainer rather than just an adjustment to your meals? We are happy to answer the latter, even if the answer means selling less.
If you prefer to order online, we ship throughout France and Europe.

Questions fréquentes — Mutant Nutrition
Mutant, c'est une bonne marque ?
Sur le gainer, oui : le Mutant Mass est l'une des références sérieuses de sa catégorie, avec une composition mieux travaillée que la moyenne — matrice protéique multi-sources, glucides variés, enzymes digestives.
Quel est le meilleur produit Mutant ?
Le Mutant Mass, et il n'y a pas de débat : c'est le produit qui a fait la marque. Le grand format de 6,8 kg est celui que prennent les habitués, une fois l'arôme choisi — d'où l'intérêt de goûter en boutique.
Quand prendre le Mutant Mass dans la journée ?
Le moment compte moins que le total calorique de la journée, mais deux repères aident. Placez-le entre les repas ou après l'entraînement, de façon à ce qu'il s'ajoute aux repas au lieu de les remplacer. Et fractionnez : deux demi-doses à deux moments différents passent très bien, surtout les premières semaines. Les jours sans entraînement, une demi-dose suffit généralement à maintenir le surplus.
Comment bien le faire passer ?
Quatre gestes simples, et la question est réglée : commencer à deux mesures, monter sur deux à trois semaines, fractionner la dose, et prévoir un bon volume d'eau en buvant lentement. Préparé à l'eau plutôt qu'au lait, il est encore plus léger pour les personnes sensibles au lactose. Près de 200 g de glucides et 56 g de protéines par dose complète, c'est un apport conséquent : la montée progressive est la clé.
Que trouve-t-on de Mutant chez nous ?
Le Mutant Mass, dont le grand format de 6,8 kg, en rayon et expédié partout en France et en Europe.
Le Mutant Mass fait-il grossir en gras ?
Il fait prendre du poids, et la répartition entre muscle et graisse dépend de ce qu'il y a autour : entraînement en résistance régulier, sommeil, et surplus calorique mesuré. C'est son mode d'emploi, et c'est dans ce cadre qu'il donne le meilleur résultat.
Quand un gainer est-il le bon choix ?
Quand manger davantage est difficile : le gainer apporte en un shaker ce qu'il faudrait ajouter en volume d'assiette. Si vous parvenez à ajouter 400 ou 500 kilocalories à votre alimentation avec du riz, des pâtes, de l'huile d'olive et du beurre de cacahuète, le résultat est le même — beaucoup de pratiquants font les deux, l'assiette aux repas et le shaker entre les repas.
Le Mutant Mass convient-il aux sportifs contrôlés ?
Si vous êtes soumis aux contrôles, vérifiez le statut du lot auprès du fabricant et référez-vous à la liste des substances interdites publiée par l'AFLD.
Peut-on l'associer à de la créatine ?
Oui, sans interaction connue : la créatine monohydrate peut être ajoutée au même shaker si cela vous simplifie la vie. C'est d'ailleurs l'association la plus rationnelle en prise de masse, la créatine étant le complément le mieux documenté du rayon. En cas de pathologie rénale ou hépatique connue, de grossesse ou d'allaitement, demandez l'avis de votre médecin avant toute supplémentation.
