Dietary Supplement. Anabolic/Anti-catabolic amino acids. The Science Behind the Size: Product: A powerful combination of the branched chain amino acids (BCAA) L-leucine, L-isoleucine and L-valine providing 2000 mg in every serving. These essential amino acids cannot be made by the body and are rapidly oxidized during exercise so supplemental BCAA"s can play a key role in muscle growth and recuperation. Result: Increased nitrogen retention and protein synthesis necessary to build muscle while preventing muscle tissue breakdown, leading to faster recovery and reduced post-workout stuffiness. Science: Research shows that branched chain amino acids increase lean muscle mass and strength. BCAA Fuel has been formulated with the specific ratio of these essential amino acids to enhance absorption and muscle tissue recovery.
