Mutant Mass Muscle Mass Gainer 6.8kg
Since 2005, Mutant Mass has been the bag of choice for hardcore bodybuilders and strength athletes who are dead serious about size. Now in its best-ever formula, the 6.8kg bag gives you 26 full servings of over 1,060 engineered calories and 52g of premium protein per shake — enough to fuel weeks of relentless training without running dry.
What sets Mutant Mass apart is the sheer complexity of its formula. The 10-source Pro-Matrix protein blend combines fast, medium, and slow-digesting proteins — whey concentrate, hydrolysate, isolate, micellar casein, milk protein concentrate and isolate — to keep amino acids flowing throughout recovery. The carbohydrate blend draws from Waxy Maize, Maltodextrin, Barley, Sweet Potato and Oat for a sustained energy release, while the lipid blend of MCT Oil, Avocado, Flax, Pumpkin and Sunflower oils adds quality fats rarely seen in mass gainers. Cinnulin PF®, Colostrum, Tart Cherry, L-Glutamine and digestive enzymes complete a formula that’s as much about recovery as it is about calories.
