About one third of skeletal muscle - the type that flexes and gets stronger when you exercise - is made up of branched-chain amino acids (BCAAs). So it shouldn't be that surprising to learn that athlete's requirements for leucine, isoleucine, and valine are higher, or that supplementing with these key aminos has been scientifically demonstrated to improve performance. STEAM BCAA helps you train longer and supports recovery with a kick-in-the-glutes combination of BCAAs (popular 2:1:1 ratio), plus added glutamine, citrulline, electrolytes, and vitamin B6. No banned substances or added sugar simply ensures training harder is also training smarter. Never run out of STEAM. These statements have not been evaluated by the Food and Drug Administration.
