Despite all positive effects of doping on the body they could be dangerous. Possible side effects of anabolic steroids can be avoided by choosing the right form (oral or injectable) and combination as well as by taking reasonable androgenic dosages. It has to be mentioned, that the most side effects of drugs disappear after the cycle is completed. Moreover, many of them can be blocked during the cycle by using respective supplements. Therefore, in order to avoid possible negative consequences one shall pay attention to studying information about the drugs prior to use them.
Oxymetholone (also known as anapolon or anadrol) is a very drastic synthetic steroid, 17-alpha-alkylated modification of dihydrotestosterone. It was developed for the treatment of osteoporosis and anaemia, as well as to stimulate muscle gain in malnourished and debilitated patients. Oxymetholone has been approved by the American Food and Drug Administration (FDA) for use in humans. Later there where created non-steroidal drugs that effectively could treat anaemia and osteoporosis; because of this anapolon lost his popularity and by 1993 Syntex decided to cease the production of the drug, as well as other manufacturers did.
