Andro Study in JAMA

CHICAGO--The Feb. 9 issue of Journal of the American Medical Association (JAMA) has published a study that considered the testosterone-increasing effects of androstenedione, a sports supplement made popular when it was touted by baseball's Mark McGwire. The study followed men who took 300 mg of andro per day for seven days.

It reported that they did, indeed, experience increased testosterone levels. Andro, which can be purchased in natural products stores, is allowed in major league baseball, the National Hockey League and the National Basketball Association. However, it is banned by the International Olympic Committee, the National Football League and the National Collegiate Athletic Association.
