Why take chances with your meal replacement - trust the unique METAMYOSYN protein blend.  The secret is the source of protein!

METAMYOSYN protein is a superior quality blend which combines premium casein with milk proteins, plus L-Glutamine and naturally occurring Branched Chain Amino Acids from protein Isoleucine, Leucine and Valine.  The precise combination of proteins in METAMYOSYN provides your body with a highly bioavailable fuel to meet your nutritional needs.

Casein is a slow-acting protein, which results in a more prolonged absorption rate to extend the delivery of amino acids to muscles.  Milk protein naturally contains both whey and casein - to provide slow and fast-digesting properties.
