Clostebol caproate

Clostebol caproate is a synthetic androgen and anabolic steroid and a derivative of testosterone. It is the caproate ester of clostebol (chlorotestosterone), which is an androgen that has been sold under the brand names Megagrisevit and Steranabol among others.

Pharmacology[edit]

Clostebol caproate is a prodrug of clostebol. Like other AAS, clostebol is an agonist of the androgen receptor (AR). It is not a substrate for 5α-reductase and is a poor substrate for 3α-hydroxysteroid dehydrogenase (3α-HSD), and therefore shows a high ratio of anabolic to androgenic activity.

Clostebol caproate, also known as 4-chlorotestosterone 17β-caproate, is a synthetic androstane steroid and a derivative of testosterone. It is the C17β caproate (hexanoate) ester of clostebol (4-chlorotestosterone), which is testosterone with a chlorine atom at the C4 position.

Clostebol caproate was first described in 1962 and was introduced for medical use by 1964.

Clostebol caproate has been used in bodybuilding and has been marketed for veterinary use.
