Mutant Mass Muscle Mass Gainer 2.2kg
The same award-winning formula trusted by hardcore bodybuilders across 100+ countries — now in a more accessible 2.2kg tub. Mutant Mass has been completely reimagined with higher protein, lower sugar, and exceptional taste, while keeping every detail that made it iconic. Whether you’re trying it for the first time or keeping a backup on the shelf, this is the tub that delivers.
Each 280g serving packs 52g of protein from the legendary 10-source Pro-Matrix blend — combining fast, medium, and slow-digesting proteins for sustained amino acid availability across the recovery window. A multi-source complex carb blend, a premium lipid matrix, plus Cinnulin PF®, Colostrum, Tart Cherry, and digestive enzymes make this far more than a simple calorie bomb.
- 52g protein per serving — 10-source Pro-Matrix (whey, casein & egg blend)
- Complex carb blend — Waxy Maize, Maltodextrin, Barley, Sweet Potato & Oat
- Premium lipid blend — MCT Oil, Avocado, Flax, Pumpkin & Sunflower
- Cinnulin PF®, Colostrum, Tart Cherry & digestive enzymes
- Higher protein, lower sugar than previous formula
- 2.2kg — 8 servings | 5 flavours available
- Sold in 100+ countries
