Cytosport Monster Milk is the ultimate anabolic mTOR activation formula. Science confirms what athletes always knew: high quality protein intake is linked to muscle size and strength. Cytosport Monster Milk is designed to help you build bigger, stronger muscles while staying lean. 50 Grams of Lean Protein help "flood" muscle fibers with a rich supply of amino acids. Whey hydrolysates, concentrates and Isolates release rapidly into the blood stream, and help boost glutathione â€“ the body's master antioxidant. The rapid nature of Whey is complemented by Micellar Casein rich milk protein concentrates/isolates and caseinates. These slower digesting proteins maintain amino acid pools and positive nitrogen balance for hours.
