Dianabol is the brand name for Methandrostenolone, an anabolic steroid derived from Testosterone.
Two alterations are made to the testosterone hormone. A double bond is added at the Carbon 1 and 2 positions and a methyl group is added at the 17th position.
This significantly reduces the androgenicity of the drug, amplifies the anabolic nature and allows it to survive, breakdown by the liver.
Methandrostenolone was marketed under the brand name Dianabol by Ciba until 1983, when it finally pulled the plug on the compound due to mounting pressure from the FDA.
But that’s the name that has been synonymous with the drug.
Some of the other nicknames that it is known by are Anabol, Danabol, Vetanabol and the D-Bomb.
