Mutant Nutrition

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.
