Testosterone isovalerate

Testosterone isovalerate, also known as testosterone isopentanoate, testosterone 17β-isovalerate, and androst-4-en-17β-ol-3-one 17β-isovalerate, is a synthetic, injected anabolic-androgenic steroid (AAS) and an androgen ester – specifically, the C17β isovalerate (isopentanoate) ester of testosterone – which was never marketed.[1][2] It is a prodrug of testosterone and, when administered via intramuscular injection, is associated with a long-lasting depot effect and extended duration of action.[1]
