ANDRO EFFECTS?

Now that the controversial supplement ephedra is off store shelves, the FDA is focusing on a new target: a steroid-like substance called Andro. Regulators want its manufacturers to either prove its safety or withdraw it.

Andro is short for androstenedione, a chemical the body uses to make testosterone and estrogen. It gained notoriety as a muscle builder in 1998, when Mark McGwire used it and hit 70 home runs.

FDA Commissioner Mark McClellan said that anyone who takes enough Andro to improve athletic performance risks "potentially irreversible health consequences." Regulators say that men taking Andro risk developing female characteristics (and vice versa)-and other side effects may include impotence and blood clots.
