Mutant Mass Extreme — serious calories for serious gainers
If you burn through food just looking at a barbell, you need more than a standard shake. Mutant Mass Extreme is a high-calorie mass gainer protein powder crafted for hard gainers who struggle to keep the scale moving. When mixed as directed, each serving lands around 1,270 calories with 46 g whey protein, 255 g carbohydrates, and 7.5 g fats — a proven formula to help you stay in surplus, support recovery, and train at full tilt.
What makes it different? The carbs and fats aren’t an afterthought. Mutant uses a whole‑food inspired blend — barley, sweet potato, and rolled oats for sustained energy, plus avocado, coconut oil, and pumpkin seeds to round out your macros. The result is a gainer that tastes like a milkshake, mixes smoothly, and fuels hard training without a sugar crash.
