MET-Rx is a brand name of nutritional supplements originally produced by Met-Rx, Inc., a California company started by A. Scott Connelly, and sold several times since. The brand is best known as the product to pioneer a new category of bodybuilding supplements known as Meal Replacement Powders or MRPs. It was also involved in the androstenedione controversy in the late 1990s. Created by Dr. Scott Connelly, the original MET-Rx product was intended to help prevent critically ill patients from losing muscle mass. Connelly's product was marketed in cooperation with Bill Phillips and the two began marketing to the bodybuilding and athletic communities, launching sales from the low hundreds of thousands to over $100 million annually. Connelly sold all interest in the company to Rexall Sundown for $108 million in 2000. MET-Rx is currently owned by NBTY. The original MET-Rx meal replacement product came in two canistersone labeled MET-Rx 'base' and the other MET-Rx 'plus.'
