Mutant Mass is the ultimate high-calorie weight gainer engineered specifically for hardgainers, bodybuilders, and dedicated strength athletes striving to pack on serious muscle size and power. Engineered to bridge the gap when whole food calories alone aren't enough, this multi-award-winning formula delivers a dense wave of premium protein, complex real-food carbohydrates, and essential healthy fats. If you struggle to gain weight or build lean body mass despite heavy training in the gym, Mutant Mass provides the clean nutritional horsepower your body needs to grow.

Key Benefits & Features

• Massive Caloric Density: Delivers up to 1,100 clean, nutrient-dense calories per full serving to easily hit your daily surplus goals.

• Multi-Stage Protein Blend: Loaded with 56g of high-quality protein to stimulate muscle protein synthesis and support continuous muscle recovery.

• Real-Food Carb System: Packed with 192g of clean carbohydrates from whole foods like sweet potato, oats, and barley to replenish muscle glycogen without extreme sugar spikes.

• Healthy Lipid Matrix: Enhanced with natural oils from coconut MCTs, avocado, and flaxseed to supply essential fatty acids and sustained metabolic energy.

• Exceptional Taste & Mixability: Blends smooth and rich into a gourmet milkshake consistency without the heavy, bloated feeling typical of cheap mass gainers.

How It Works

Mutant Mass works by flooding your muscles with a precise combination of fast- and slow-releasing nutrients immediately when your body needs them most. The multi-stage protein matrix—featuring whey protein concentrate, hydrolysed whey, whey isolate, micellar casein, and milk proteins—provides a continuous feed of essential amino acids and BCAAs to keep your body in an anabolic state.

Instead of relying on cheap sugars that cause energy crashes, the real-food carbohydrate architecture supplies steady, sustained energy to drive heavy resistance sessions and restore depleted glycogen stores. Coupled with medium-chain triglycerides (MCTs) and healthy fats, Mutant Mass ensures you absorb maximum calories for rapid physical growth while staying light enough on the stomach for daily consumption.

Recommended Use

Mix 4 scoops (280g) of Mutant Mass with 480ml–960ml of cold water or full-cream milk in a shaker or blender. Consume immediately post-workout to kickstart recovery, or enjoy it between main meals to boost your daily caloric intake.

Tip for New Users: If you are new to high-calorie gainers, begin with a half serving (2 scoops) mixed in 240ml–480ml of liquid twice daily between meals to allow your digestive system time to adapt.
