Stenbolone, also known as 2-methyl-δ¹-4,5α-dihydrotestosterone (2-methyl-δ¹-DHT) or as 2-methyl-5α-androst-1-en-17β-ol-3-one, is a synthetic androstane steroid and a derivative of DHT.^[1][3] It is closely related structurally to drostanolone (2-methyl-DHT), 1-testosterone (δ¹-DHT), and methylstenbolone (17α-methylstenbolone).^[5]
