Methandienone (also known as methandrostenolone, Dbol, dianabol) is an orally-effective anabolic steroid originally developed in Germany and released in the US in the early 1960s by Ciba Specialty Chemicals. This is a derivative from testosterone, one of the most popular steroid compounds in the world and the second steroid (after testosterone) ever produced. Methandienone promotes dramatic increases in protein synthesis, glycogenolysis, and muscle strength over a short space of time.

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.
