Trenbolone undecanoate , or trenbolone undecylate , is a synthetic and injected anabolic–androgenic steroid (AAS) and a derivative of nandrolone (19-nortestosterone) which was never marketed.[1] [2] It is the C17β undecanoate (undecylate) ester and a long-acting prodrug of trenbolone .[1] [2] The drug was described by Roussel Uclaf in 1967 and was the first long-lasting ester of trenbolone to be developed.[1] [2] Subsequently, trenbolone hexahydrobenzylcarbonate , a roughly equivalent compound, was developed and introduced for use in humans in 1980, though it was discontinued in 1997.[2] Trenbolone enanthate is another long-lasting ester of trenbolone.[2] Similarly to trenbolone undecanoate, it was never marketed, but it has been sold on the black market as a designer steroid for bodybuilders and athletes .[2]
