Clostebol (; also known as 4-chlorotestosterone) is a synthetic anabolic–androgenic steroid (AAS). Clostebol is the 4-chloro derivative of the natural hormone testosterone. The chlorination prevents conversion to dihydrotestosterone (DHT) while also rendering the chemical incapable of conversion to estrogen. Although usually used as an ester including clostebol acetate (Macrobin, Steranabol, Alfa-Trofodermin, Megagrisevit), clostebol caproate (Macrobin-Depot), or clostebol propionate (Yonchlon), unmodified/non-esterified clostebol is also reported to be marketed, under the brand name Trofoderm
