Mutant Mass is a high-calorie weight gainer designed to support serious bulking phases and demanding training programmes. Built around a blend of complex carbohydrates, multi-source protein and essential fats, Mutant Mass provides a substantial calorie intake for individuals aiming to increase overall bodyweight and support muscle growth when combined with consistent resistance training.
Each serving delivers a powerful combination of protein and carbohydrates, making it suitable for hard gainers, strength athletes and those struggling to consume enough calories through food alone. The formula includes whole food carbohydrate sources such as barley, sweet potato and oats, alongside quality whey proteins to help support recovery and muscle repair.
Mutant Mass is particularly popular during dedicated mass-building phases where calorie surplus is essential. It can be used post-workout, between meals or before bed to help increase daily energy intake and support progression in the gym.
