Peptide Linked Branched Chain Aminos. Peptide Linked Branched Chain Aminos. Lean muscle Ð 2 grams + CLA (Conjugated Linoleic Acid). Mind/muscle Ð 500 mg (Agmatine Sulfate). BPI SPORTS BEST BCAA is not your typical, run-of-the-mill, same as everyone else, outdated BCAA product. Not even close. This formula is the first to bond the three branched chain amino acids - leucine, isoleucine and valine - utilizing a proprietary process route, to form oligopeptides (a bonded chain of amino acids; for example, a peptide linked chain). The oligopeptide-based branched chain amino acids may act as a better transport vehicle, allowing for more efficient metabolization, greater bio-activity, enhanced onset time, and a generally improved BCAA model. And, the scientific minds at BPI Sports didn't stop here ... for maximum potential benefit, the oligopeptide branched chain amino acids in BEST BCAA are delivered via complex bio-active Oligopeptide-Enzymatic Technology. In addition, this unique and unrivaled product also incorporates CLA (Conjugated Linoleic Acid) and Agmatine Sulfate. The scientific literature suggests CLA and Agmatine have properties that may enhance lean muscle-building programs.
