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.
