<unk>  (; also known as 4-chlorotestosterone) usually as the ester<unk>  acetate, is a synthetic anabolic–androgenic steroid (AAS).<unk>  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<unk>  acetate (Macrobin, Steranabol, Alfa-Trofodermin, Megagrisevit),<unk>  caproate (Macrobin-Depot), or<unk>  propionate (Yonchlon), unmodified/non-esterified<unk>  is also reported to be marketed, under the brand name Trofodermin-S in Mexico.<unk>  is a weak AAS with potential use as a performance enhancing drug. It is currently banned by the World Anti-Doping Agency. Chlorodehydromethyltestosterone (Oral Turinabol), combining the chemical structures of<unk>  and metandienone, was widely used in the East German state-sponsored doping program.
