Founded in 1991, Met Rx Engineered Nutrition revolutionized the sports nutrition industry with a high protein, meal replacement shake fortified with an exclusive protein blend called Metamyosyn. Developed by a physician based on metabolic research, Metamyosyn protein is a highly bio-available fuel that supports muscle and strength. Today, Met Rx offers a diverse range of products engineered for the next generation of athletes – all those who use state-of-the-art nutrition to achieve their goals and who never, ever accept limits of mind, body or spirit.

MET-Rx Ultramyosyn Whey is a great tasting blend featuring ultra-filtered whey protein concentrate. Whey protein has one of the highest biological values of any protein source due to its excellent amino acid availability and digestibility. A high biological value means that it may yield more usable grams of amino acid.

MET-Rx recognizes that some people find it hard to digest milk, which is why Ultramyosyn Whey is designed to be mixed with water and still tastes great. For those that feel casein in milk is beneficial to their regimen, MET-Rx Ultramyosyn Whey also mixes easily with milk for slower digestion.

MET-Rx Arsenal Training Packs provide the firepower of essential vitamins, minerals, aminos, essential fats, digestive enzymes and other nutrients necessary to stay in the fight.
