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.

April 14, 2007 Reviewer: David in Nebraska I have been using this product for years. Because of my busy schedule, it has been hard to maintain a good diet. Met-Rx meal replacement shakes have enabled me to maintain a healthy lifestyle. I am currently deployed to Iraq and find the use of this product more needed now than ever before. This review is specific to MET-Rx Drink Mix, Extreme Chocolate Was this review helpful to you? Yes  No October 03, 2009 Reviewer: Thomas in Wisconsin I have been using Met-Rx for years. One/two packets per day and it is a great "when I need to cut the Calories to 1500 per day, Always top of the list supplement"! Was this review helpful to you? Yes  No October 03, 2009 Reviewer: Thomas in Wisconsin Top of the line supplement. One Met-rx per day does wonders! This review is specific to MET-Rx Drink Mix, Original Vanilla Was this review helpful to you? Yes  No April 01, 2009 Reviewer: Jerry in Massachusetts The new formula for Extreme Chocolate is good. Not much change from the old one. Was this review helpful to you? Yes  No June 10, 2008 Reviewer: Jeffery in New Jersey The best meal replacement hands down. I have been using this for 10 plus years, and it tastes fantastic and keeps me lean and muscular year round. I am glad that they still make "white box" and discontinued the newer (and awful) "red box" formula. The vanilla tastes like cake, and the chocolate tastes like ice cream. I look forward to this shake every afternoon. Was this review helpful to you? Yes  No See more reviews
