Mutant Mutant Mass
Mutant Mass is a high-calorie weight gainer for people who struggle to eat enough to put on size. One serving gives you over 1,100 calories and 56g of protein in a shake, which is far easier to get down than another full plate of food. It has been a go-to with bodybuilders and strength athletes for years.
What you get per serving
- Over 1,100 calories to help you reach a calorie surplus
- 56g protein. Protein contributes to the growth and maintenance of muscle mass
- 36g of naturally occurring BCAAs, EAAs and glutamine
- Carbohydrates from whole-food sources including oats, sweet potato and avocado
- Less sugar than the previous recipe
Who it's for
Mutant Mass suits "hard gainers": people with big appetites for training but small ones for food, fast metabolisms, or busy days that make six meals impossible. If you only need extra protein rather than extra calories, a standard whey such as Skill Nutrition Whey is a better fit.
How to use it
A full serving is a big shake, so many people split it into two smaller shakes across the day, for example one after training and one between meals. You can also start with a half serving and build up. Check the pack for the exact serving size and mixing amount for your bag.
Sizes and flavours
2,270g and 6,800g bags, in Coconut Cream, Triple Chocolate, Chocolate Fudge Brownie, Cookies & Cream, Strawberry Banana and Vanilla Ice Cream.
Frequently asked questions
Will a weight gainer make me fat?
A gainer simply adds calories. Whether that becomes muscle or fat depends on your total intake and your training. Pair it with regular resistance training and adjust your serving if you're gaining too fast.
Can I mix it with milk?
Yes, though it's already very high in calories with water. Milk adds more calories and protein if you need them.
