If the scale won't move no matter how much you train, the problem is almost always calories — and Mutant Mass 15lb exists to fix exactly that. A full serving delivers over 1,100 calories and 56g of protein, turning one shake into the nutritional equivalent of an extra meal.

What separates Mutant Mass from sugar-bomb gainers is its carbohydrate and fat sourcing: complex carbs from oats, barley and sweet potato, plus fats from avocado, coconut, flaxseed and pumpkin seed oils. You get calories that fuel training rather than just spiking blood sugar.

Per Full Serving

• 1,100+ calories for a reliable daily surplus
• 56g protein from a quality multi-source blend
• Whole-food complex carbohydrates for sustained energy
• Healthy fats for calorie density and balanced nutrition
• Naturally occurring BCAAs and EAAs

How to Use

Blend one serving with cold water or milk and drink post-workout or between meals. New to gainers? Start with half servings and work up as your appetite and calorie targets allow — the 15lb bag will keep you supplied for months either way.

Who It Suits

Hard gainers, fast metabolisms, athletes with brutal training loads, and anyone in a dedicated bulking phase who's tired of force-feeding.
