The renowned MET-Rx protein formulation consists of METAMYOSYN, which combines premium whey protein isolates and casein proteins, plus L-Glutamine and naturally occurring Branched Chain Amino Acids from protein — Isoleucine, Leucine and Valine. Whey is a fast-acting protein while casein is slow-acting, which results in a more prolonged absorption rate to extend the delivery of amino acids to muscles. Milk protein is a natural source of whey and casein. MET-Rx Protein Plus gives you a firm nutritional basis to help build lean muscle in a low-fat, great tasting formula.

Still the best!There's no other protein on the market that satisfies like the Protein Plus. It mixes up nice and thick, no stomach discomfort, and tastes awesome. I was a huge MetRx fan in the 90's and i keep coming back to this formula today.
