How it works

Extensive human evidence confirms its efficacy for increasing muscle protein synthesis and lean mass when paired with resistance training. It is a complete protein with high bioavailability and rapid absorption.

Provides a concentrated source of essential amino acids, particularly leucine, which activates the mTOR pathway to initiate muscle protein synthesis.
