WarriorLab's revolutionary Complete Intra formula contains literally EVERYTHING the body needs during an intense workout to ensure maximum performance, strength and faster recovery. Initially it contains BCAA amino acids and in fact in the right 2: 1: 1 ratio, with special emphasis on Leucine, which is the amino acid which apart from the strongest anti-catabolic amino acid is the one that essentially plays the role of "traffic warden" that allows and accelerates flow of the remaining amino acids directly to the muscles.
