Trestolone enanthate

Trestolone enanthate is a synthetic and injected anabolic–androgenic steroid (AAS) and a derivative of nandrolone which was never marketed. It is an androgen ester – specifically, the C17β enanthate ester of trestolone (7α-methyl-19-nortestosterone; MENT).

Pharmacology

As an AAS, trestolone enanthate is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has strong anabolic effects and weak androgenic effects, which give it a mild side effect profile and make it especially suitable for use in women. The drug has no estrogenic effects but can have progestogenic effects, which can mimic estrogenic side effects.

Chemistry

Trestolone enanthate, also known as 7α-methyl-19-nortestosterone 17β-enanthate, is a synthetic estrane steroid and a derivative of nandrolone. It is more specifically a derivative of 19-nortestosterone and is a member of the estrane group, while a derivative of 17β-hydroxyestra-4,9,11-trien-3-one (trenbolone), a derivative of progesterone, is a member of the estratetraene group.

History

Trestolone enanthate was first described in the literature in 1963. It was studied for use in male hormonal contraception and treatment of male hypogonadism but was never marketed.

Society and culture

Trestolone enanthate is not currently approved for medical use and it is not available as a prescription medication. However, it has been sold on the internet as a designer steroid for bodybuilders and other athletes.
