As the product grew more popular, it was released as one formula combining the "base" and "plus" while removing the

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.
In February 1995, the Penn State Sports Medicine Newsletter (3;6) published a report titled "Is It Real or Is It Met-Rx?" that concluded, "MET-Rx ... claims of fat loss and increased muscle mass have not been proven by scientifically accepted methods."

MET-Rx also sponsors dozens of athletes, bodybuilders, and celebrities, as well as being the primary sponsor of the World's Strongest Man competition.
In early interviews and promotional materials, Connelly marketed himself as a 1973 Harvard Medical School graduate, and claimed he was on the faculty of Stanford Medical School between 1979 and 1986. However, Connelly was only at Harvard as a post-grad "special student" in the 1973–74 academic year. He then got his Doctor of Medicine in anesthesia from Boston University School of Medicine in 1978 and did a one-year Stanford fellowship in 1981. Connelly was an unpaid clinical instructor and was never part of the full-time faculty at Stanford.
