Product Summary

Mutant Mass is a clean high-calorie weight gainer specifically designed for bodybuilders and weightlifters. Each serving of this supplement is packed with 1,100 calories, 56 grams of protein, 192 grams of carbs, and 12 grams of high-quality plant-based fat. The taste is what makes Mutant Mass stand out as consumers rave over both the consistency and taste of all six flavors. There are claims by several users that this supplement is the best they have ever tasted.

The complex protein blend includes whey protein concentrate, casein, and milk proteins. Although the fat content is high, it is derived from natural sources including MCT oil, avocado, flaxseed, pumpkin seed, and sunflower oils. 192 grams of clean carbohydrates come from whole food sources including barley, sweet potato, rolled oats, and maltodextrin to keep you satiated.

Unfortunately, Mutant Mass has a notable sugar count. Topping off just under 20 grams of sugar per serving, it falls on the higher end of sugar content for weight gainers. Overall the macro count is impressive. Jam-packed with whole foods, Mutant Mass will effectively help you pack on some pounds.
