MET-Rx Protein Plus was invented to give you the competitive advantage especially when it comes to quality protein! Each high-protein serving provides better than a 5:1 ratio of protein to carbs to help meet your nutritional goals. Best of all, MET-Rx Protein Plus contains no added sugar1, corn syrup solids, mono- or diglycerides and now is free of aspartame and hydrogenated oils - which means no trans-fats!The Secret is in the Protein Source!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 - Isoleucine, Leucine and Valine. Studies show that 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.* MET-Rx Protein Plus gives you a firm nutritional basis to help build lean muscle in a low-fat, great tasting formula.*Results may vary.
