An NBC DateLine broadcast on October 6, 1996, entitled "Hype in a Bottle" investigated MET-Rx USA, Inc. The report revealed that MET-Rx had failed to provide published peer-reviewed documentation to substantiate its advertising claims. In October 1993 the "MET-Rx Substantiation Report" was provided to David Lightsey of the National Council Against Health Fraud. The report claimed association with Cooper Clinic in Dallas, Texas. The report noted that several Dallas Cowboys players had gained an average of 2.5 to 3 pounds of lean body mass weekly for six weeks when using a MET-Rx product -- an obvious red flag. Cooper Clinic was contacted of possible misrepresentation. Cooper Clinic issued a cease and desist letter to Met-Rx from the Cooper Clinic president and medical director.
