MET-Rx® "Original" Meal Replacement revolutionized sports nutrition with the Metamyosyn® Protein Blend. Now new and improved, the "Original" MET-Rx® Meal Replacement is back and better than ever with an upgraded formula that is free of aspartame and hydrogenated fats while still featuring the exclusive Metamyosyn® Protein Blend.

Complete protein blend to help build lean muscle. Originally developed by a physician, Metamyosyn® protein is based on metabolic research to help support lean muscle mass studied in three published clinical trials. In a groundbreaking study, subjects using MET-Rx® Original Meal Replacement twice per day gained more muscle and strength over 12 weeks than a group receiving whey protein only supplements. Metamyosyn® combines Milk Protein with fast-digesting whey protein and slow-acting casein, plus L-Glutamine and naturally occurring Branched Chain Amino Acids - Isoleucine, Leucine and Valine. The precise combination of proteins in Metamyosyn® offers a sustained release of amino acids for up to 7 hours and provides your body with a highly bioavailable fuel that helps build lean muscle mass and strength.

Use MET-RX® Meal Replacement any time of the day:

• Immediately After Exercise: Makes an excellent post-workout shake by providing fast digesting proteins for immediate muscle support plus slow digesting proteins for extended amino acid delivery and recovery.
• With Meals: Drink along with your meal to increase the overall protein quality and content. You can also mix into oatmeal or add to recipes such as pancake and waffle mixes.
• In Between Meals: Keeps levels of amino acids elevated so your body doesn’t go into a catabolic state that may otherwise lead to muscle loss.
• Before Bed: The high content of slow-digesting proteins in MET-Rx® Meal Replacement makes it a perfect before-bed supplement as it provides “time-released” amino acid delivery to your body while you sleep.
