The name Superdrol is short for “Super Anadrol”, however this drug is also known as methasteron and methyldrostanolone. Superdrol is a close derivative of drostanolone (masteron). The only difference to the molecule is the addition of a c17 alpha methyl group, this was done to allow oral administration. Superdrol share many characteristics of its parent hormone Masteron, both are non-aromatizable so estrogenic activity is minimal. Androgenic side-effects are very rare, but still possible.
