Oxymetholone is considered as a derivative of dihydrotestosterone (DHT), has a reputation of being the strongest oral AS available. It is both highly anabolic and androgenic; therefore it is very toxic to the liver. There have been many reports of acne and hair loss (due to its dihydrotestosterone characteristics) in addition to its strong association with liver damage and gynaecomastia. There have also been reports of headaches and stomach pains. There is substantial evidence of loss of size and weight, which has been attributed to the drug being too hard on the body. Very few women are able to tolerate oxymetholone because of its dominant androgenic effects such as virilization. Because of its such side effects, it is recommended to keep the usage below six weeks. In addition to this it could be poor choice for those who are naturally prone to high blood pressure.
