Methasterone resurfaced in 2005 as a “designer steroid”. It was brought to market by Designer Supplements as the primary ingredient of a dietary supplement named Superdrol.
Methasterone, also known as 2α,17α-dimethyl-5α-dihydrotestosterone (2α,17α-dimethyl-DHT) or as 2α,17α-dimethyl-5α-androstan-17β-ol-3-one, is a synthetic androstane steroid and a 17α-alkylated derivative of DHT.
