Label Facts


The original Meal Replacement Protein Powder from MET-Rx revolutionized sports nutrition with the Metamyosyn Protein Blend; this latest version retains the protein whithout the aspartame and hydrogenated fats.

Originally developed by a physician, Metamyosyn protein is based on metabolic research to help support lean muscle mass. Metamyosyn combines milk protein with slow-acting casein, plus L-glutamine. Milk protein is a natural source of whey and casein, for fast and slow digesting properties, and each protein source within Metamyosyn provides naturally occurring Branched Chain Amino Acids - Isoleucine, Leucine and Valine.

The precise combination of proteins in Metamyosyn offers a sustained release of amino acids and provides your body with a highly bioavailable fuel that helps support lean muscle mass and strength.
