The famous baseball player, Mark McGwire, hit 70 home runs during the 1998 baseball season. But many people wondered if his success was the result of taking two supplements. He was taking a steroid called “andro” and a compound called creatine. Creatine is a compound found in the muscle tissue of vertebrates.
According to the Dietary Supplement and Health Act of 1994, they are both considered dietary supplements, not drugs. Supplements can be sold over the counter to anyone. Drugs can not.
The steroid, andro, can temporarily increase one’s testosterone levels. However, there is no proof that it improves athletic performance. Creatine can temporarily improve a person’s physical performance, but not by much.
The use of these supplements is banned in baseball, in the Olympics, and in football. They were not banned in baseball when Mark McGwire was taking them.
