THE SECRET IS THE SOURCE OF PROTEIN!

Brand IP Statement(s) re: (c), (TM), (SM)

METAMYOSYN(R) protein, based on metabolic research to help support lean muscle mass, was originally developed by a physician and has been studied in three published clinical trials. In a groundbreaking study, subjects using MET-Rx(R) Original Meal Replacement twice per day gained more muscle and strength over 12 weeks than a group receiving whey protein only supplements. METAMYOSYN(R) protein is a superior quality blend which combines premium casein with whey and milk proteins, plus L-Glutamine and naturally occurring Branched Chain Amino Acids - Isoleucine, Leucine and Valine. The precise combination of proteins in METAMYOSYN(R) provides your body with a highly bioavailable fuel to meet your nutritional needs.

General Statements: All Other Content

Research 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. Milk protein naturally contains both whey and casein - to provide slow and fast-digesting properties.

General Statements: All Other Content

Use MET-Rx(R) Meal Replacement any time of the day including: 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.
