Performance-Enhancing Drugs That Are Not Banned

Are there any drugs to make athletes stronger that are not banned?

Some athletes take estrogen blockers and human chorionic gonadotropin (Journal of Clinical Endocrinology & Metabolism, Volume 91, 2006), which have not been banned by sports authorities such as the Olympic committee. Estrogen blockers such as Tamoxifen, Arimedex, Aromasin, and Femara are used to treat women with, or at high risk, for breast cancer. Evidently lowering the female hormone, estrogen, may act the same way as raising the male hormone, testosterone, to help athletes recover faster from hard workouts. Human chorionic gonadotropins are hormones that are produced in very large amounts by a woman's body when she is pregnant. These hormones appear to promote cell growth, which includes muscle tissue.

Both male and female athletes can experience strength gains from these hormones or anti-hormones. Since nobody really knows all the side effects that occur when healthy athletes take them, the athletes may be risking their lives.
