BCAA or glutamine? This eternal question is no more discussed, as the answer is: both!  Their supplementation can come in handy before, during and after high-intensity or prolonged trainings, as high percentage of your solid muscle mass is built up by BCAAs (L-leucine, L-isoleucine, L-valine) and glutamine (in cooperation with the other amino acids). Have them from now on as a pair! By using the BioTechUSA BCAA + Glutamine Zero product you can supplement both in an easy and practical way. Do not stop at halfway, give an extra boost to your muscles!
