Branched Chain Amino Acids (BCAA's) are essential for growth and recovery as the human body cannot produce them. This combination of amino acids have been extensively studied for their potential anti-catabolic (preventing muscle breakdown) and anabolic (muscle building) effects.
Black Widow BCAA's consist of the proven 4:1:1 ratio of the amino acids (L-Leucine, L-Isoleucine and L-Valine), which research suggests will assist with muscle building by supporting increased protein synthesis, as well as assist you with energy you need to maximise your training, enhance recovery and assist in avoiding fatigue by blocking the entry of tryptophan into the brain.
