It is an androgen ester – specifically, the C17β acetate ester of clostebol (4-chlorotestosterone) – and acts as a prodrug of clostebol in the body. Clostebol acetate is administered via intramuscular injection.
Clostebol caproate, also known as clostebol hexanoate or chlorotestosterone caproate (JAN), as well as 4-chlorotestosterone 17β-caproate or as 4-chloroandrost-4-en-17β-ol-3-one 17β-caproate, is a synthetic, injected anabolic-androgenic steroid (AAS) and a derivative of testosterone. It is an androgen ester – specifically, the C17β caproate ester of clostebol (4-chlorotestosterone) – and acts as a prodrug of clostebol in the body. Clostebol acetate is administered via intramuscular injection.
Clostebol propionate, also known as 4-chlorotestosterone 17β-propionate or as 4-chloroandrost-4-en-17β-ol-3-one 17β-propionate, is a synthetic, injected anabolic-androgenic steroid (AAS) and a derivative of testosterone. It is an androgen ester – specifically, the C17β propionate ester of clostebol (4-chlorotestosterone) – and acts as a prodrug of clostebol in the body.

Testosterone valerate, or testosterone pentanoate, also known as androst-4-en-17β-ol-3-one 17β-valerate, is a synthetic, steroidal androgen and an androgen ester – specifically, the C17β valerate ester of testosterone – which is used in veterinary medicine. It is administered via intramuscular injection and acts as a long-lasting prodrug of testosterone. The medication is available as a component of the veterinary drug Deposterona, which is marketed in Mexico and also contains testosterone acetate and testosterone undecanoate. Testosterone valerate is a short-to-medium duration ester of testosterone, with an elimination half-life of approximately twice that of the short-acting testosterone propionate.

Its ester side-chain length and duration of effect are intermediate between those of testosterone propionate and testosterone valerate.
Testosterone benzoate, or testosterone 17β-benzoate, also known as androst-4-en-17β-ol-3-one 17β-benzoate, is a synthetic, injected anabolic–androgenic steroid (AAS) and an androgen ester – specifically, the benzoate C17β ester of testosterone – which was never marketed. 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. The drug was first described in 1936 and was the first androgen ester and ester of testosterone to be synthesized.
