International Protein Extreme Mass

Extreme Mass is a weight gainer protein, designed for lean mass gainers. This mass gainer includes 5 types of protein as well as a unique selection of complex carbohydrates and a healthy blend of canola and sunflower oils combined with fast-burning MCT Oils.

One of the key attributes that set Extreme Mass apart from other mass gainers on the market is that it is a genuine energy-rich high-calorie weight gainer, not just a carbohydrate-heavy formulation that is passed off as a mass gainer.
