Practical BCAA or glutamine ? This eternal question is no longer discussed, as the answer is: both! Supplementation can be useful before, during and after high intensity or prolonged training, since a high percentage of your solid muscle mass is made up of BCAAs (L-leucine, L-isoleucine, L-valine) and glutamine (in cooperation with the other amino acids). Take them from now on in pairs! By using the product BioTechUSA BCAA + Glutamine Zero you can complement both in an easy and practical way, don't stop halfway, give an extra boost to your muscles!
