Overview
A multi-source protein blend and slow-burning carbohydrates from oats, barley and sweet potato are the working parts of Mutant Mass Extreme, a powder made for hard gainers. BCAAs and glutamine are added.
The calorie load is the point, aimed at people who struggle to eat enough to gain weight. With up to a very high calorie count in one serving, it is not a casual protein shake, and the number of servings per tub is not stated.
Who it's for
Post-workout or between-meal shakes mixed with water or milk are the use the listing describes. People watching their weight or sugar intake should choose a standard whey powder instead.
Pros and cons
- Very high calories per serving

Performance notes
Calories scale with the amount mixed and the liquid used, since milk adds more than water. Carbohydrates from oats, barley and sweet potato release energy more slowly than sugar. Protein from several sources supports muscle recovery after training.
