Real food. Real calories.
Real hardcore mass.

Why we created MUTANT MASS®

There’s no such thing as too massive. That’s why mutant mass® exists. Real gains need real food ingredients, not unnecessary fillers & chemicals. Science-based, real macros formulated —
not some weak-ass bs.

it works

We know you pay attention to every macro and are undoubtedly a label reader. You have probably noticed that most mass builders contain a ridiculous concoction of chemicals, fillers, and creamers. It’s time to kick the bullsh*t to the curb and get real about what you’re feeding your muscles! Mutant Mass gives you quality calories, carbs, fats, and protein from natural food sources like avocado, rolled oats, and sweet potato, not creamers, chemicals, and unnecessary fillers.†

Demystify gains, and become a force of nature.

Supplement facts

Each full serving of Mutant Mass contains 56 grams of protein from six sources, including Whey Protein Concentrate, Hydrolyzed Whey Protein, Whey Protein Isolate, Micellar Casein Protein, Milk Protein Concentrate, and Milk Protein Isolate. Why six sources of protein? Beyond nutrient and other benefits unique to each protein source, each source has different absorption rates, benefiting your muscles differently.
For example, hydrolyzed protein can absorb quickly to feed your muscles after tough training sessions, while micellar casein protein is slow-absorbing for extended muscle nourishment and recovery.

Packed with naturally occurring BCAAs and EAAs to support the massive muscle gains you work so hard for. Mutant Mass also contains 10.4 grams of naturally occurring glutamine. Although glutamine is a non-essential amino acid, it can be highly essential and beneficial to supporting muscle growth and repair when you are grinding hard and trying to pack on massive gains.

Wouldn’t you rather feed your muscles with nutrient-dense carbs
and fats from real food sources instead of a bunch of junk? Mutant Mass contains a carb blend with nutritious food ingredients like Waxy Maize Corn Starch, Barley Starch, Sweet Potato, and Rolled Oats.
Not all fats are equal, and not all fat is bad. Mutant Mass contains “good” fats that can play an essential role in promoting muscle growth and are derived from nutrient-dense sources like avocados, coconut MCT oil, flax seeds, and pumpkin seeds.

Mutant® Mass was carefully formulated to support your gains
without adding a bunch of unnecessary junk. When you read the labels of many mass builders, it looks like a nasty concoction of chemicals and fillers. If you’re drinking something daily to pack on massive gains, you don’t want that! Mutant Mass uses clean ingredients when
possible over highly processed junk ingredients like vegetable creamers, which are often made with other junk ingredients like
corn syrup solids - yuck!
