If this is your first time using MUTANT® MASS, we recommend you start by mixing 2 scoops with 2 cups of cold water or milk (for extra calories) to assess tolerance. Because MUTANT® MASS is very high in calories, it can cause some to experience stomach discomfort if you’re not used to eating a lot of calories all at once.

On training days, take 1 serving (4 scoops) of MUTANT MASS immediately after your workout. On non-training days, it’s best to take 2 scoops anytime in the morning and another 2 scoops anytime in the afternoon.
Liquid first, protein powder second = no clumps.

For those serious about gaining weight and consuming additional calories, milk is a great option to mix with MUTANT MASS.

Look, shit happens — if you can’t eat a meal or don’t have the time, then yes, use MUTANT® MASS. It’s always best to get in the calories you need rather than go too long without eating, especially when trying to build muscle. Besides, MUTANT® MASS contains high-quality protein, carbs, and fats, so it’s made of real food!

Each serving of MUTANT MASS contains a 242g blend of carbohydrate sources that includes sweet potato, rolled oats, barley, and waxy maize.

Each serving of MUTANT MASS contains a 21g blend of high-quality plant-based fat sources, including MCT oil (coconut oil), avocado, flaxseed, pumpkin seed, and sunflower oils.

No, MUTANT MASS contains a superior blend of proteins containing whey protein concentrate, casein, and milk proteins, all containing lactose.

The expiration date on Mutant Mass is usually printed on the bottom of the bag next to the lot number. The expiration date format is mm/year.

Yes. Every product we make is tested to meet both Health Canada (CFIA) and U.S. FDA safety standards for heavy metals.
We source over 500 ingredients from more than 20 countries, so we never rely on assumptions about safety — we rely on testing.
Each ingredient and finished product goes through rigorous Quality Control checks, including:

• Microbiological tests (for mold, yeast, salmonella, E. coli, and bacteria)
• Heavy metal testing (for lead, mercury, cadmium, and others)

For certain ingredients, like whey protein, we go even further — testing for listeria, a rare but serious pathogen.
In addition, many of our products also undergo third-party verification such as Informed Choicetesting for banned substances, ingredient identity, potency, and protein accuracy.
Our goal is simple: to ensure every product is safe, clean, and compliant, no matter where its ingredients come from.
