Additional Information

Monster Amino PST (Protein Synthesis Threshold) is a concentrated BCAA formula that delivers an 8:1:1 ratio of Leucine to Isoleucine to Valine. Recent university research shows that Leucine enriched beverages consumed with exercise synergistically activate and prolong activity of the mTOR signaling pathway, which increases muscle anabolic potential (muscle growth). 1,2,3 The mTOR pathway is the “trigger” that signals the very genesis of muscle protein synthesis.** (Molecular Drawing) 8: LEUCINE 1: ISOLEUCINE 1: VALINE
