The Drugs

Clomiphene Citrate: A prescription drug typically used for the treatment of female infertility, it is taken by male athletes to negate the effects of increased estrogen, a result of anabolic steroid abuse.

Human Chorionic Gonadotropin (HCG): A hormone produced naturally during pregnancy, HCG is taken by anabolic steroid users to stimulate the production of testosterone, which is suppressed as a result of steroid use.

Human Growth Hormone (HGH): The primary purpose of the naturally occurring growth hormone is the maintenance of normal bone growth from birth to adulthood. Synthetic HGH is typically used by physicians to treat growth disorders, but athletes often abuse the drug to build muscle and decrease fat, usually in conjunction with anabolic steroids. The generic name for synthetically produced HGH is somatropin; brand names include Genotropin and Saizen.

Nandrolone: This synthetic anabolic steroid has been used to treat anemia, osteoporosis and breast carcinoma. It builds muscle and increases red-blood-cell count.

Stanozolol: This synthetic anabolic steroid is typically used to treat a rare immune disease in humans and to increase appetite, muscle mass and energy in animals--often horses recovering from illness or injury. It might be preferred by athletes who value speed because it doesn't build muscle quickly. Also, some abusers claim that stanozolol, unlike some other steroids, doesn't cause water retention. Winstrol is a brand name.

Trenbolone: A synthetic anabolic steroid that some claim is a more potent muscle builder than testosterone, it promotes red-blood-cell production and increases the rate of glycogen replenishment, both of which aid in postworkout recovery.
