Amino Synergy is formulated with a leucine-enriched EAA matrix. MP9 supports the mTOR signaling pathway and protein synthesis.* mTOR is the body’s master protein synthesis regulator. This powerful pathway controls the anabolic and catabolic signaling of skeletal muscle mass, regulating muscle growth and muscle wastage (breakdown). Amino Synergy delivers a combination of leucine-enriched EAAs to help combat muscle breakdown and support protein synthesis so you can start maximizing the results you work hard for in the gym and on the field.
