Androisoxazole

Androisoxazole (brand names Androxan, Neo-Ponden, Neo-Pondus), also known as 17α-methyl-5α-androstano[3,2-c]isoxazol-17β-ol, is an orally active anabolic-androgenic steroid (AAS) and a 17α-alkylated derivative of dihydrotestosterone (DHT) that is marketed in Spain and Italy.^[1][2][3][4] It is closely related to stanozolol, differing only in having an isoxazole instead of pyrazole ring fused to the A ring,^[4] and is also related to furazabol, prostanozol, and danazol.
