Oxymetholone (Anadrol), is a synthetic anabolic steroid developed by Syntex in 1960. Its primary clinical applications include treatment of osteoporosis and anaemia, as well as stimulating muscle growth in undernourished or underdeveloped patients. The drug was approved for human use by the FDA. However, later non-steroidal drugs such as Epogen were developed and proven to be more effective as a treatment for anaemia and osteoporosis without the side-effects of oxymetholone. The drug remained available despite this, and eventually found a new use in treating HIV wasting syndrome. While classified as a Schedule III drug under the Controlled Substances Act, it remains available via prescription as Anadrol (registered as a trademark of Unimed Pharmaceuticals.)

Presented most commonly as a 50 mg tablet, Oxymetholone is the strongest androgenic steroid available. Similarly, it also poses the greatest risk of side effects of any steroid.
Despite very low binding affinity with the androgen receptor, oxymetholone is highly effective in promoting extensive gains in body mass, mostly by greatly improving protein synthesis. For this reason, it is often used illegally by bodybuilders and athletes. Many athletes also use Oxymetholone as a method of protection for the joints under heavy loads. Due to the high water retention users experience from this drug, it similarly lubricates the joints and helps protect them from injury. Oxymetholone is widely considered by bodybuilders to have the strongest anabolic effect out of any oral steroid available; weight increases of 20 pounds in 2 weeks are not unusual of with this drug.
