Transparency is the foundation of the NutraBio legacy.

This commitment to quality makes Extreme Mass the definitive choice for athletes who prioritize long-term health as much as they do physical size.

Beyond its impressive macronutrient profile, this Clean Mass Gainer Protein is a complete "Dietary Essential" kit. It is fortified with fiber and essential vitamins to support the metabolic demands of a high-calorie diet, ensuring your body can efficiently process and utilize the nutrients for fuel. The rich Chocolate flavor is designed for smooth mixability, avoiding the clumping and "grit" often associated with high-calorie powders.
