Trenbolone enanthate is a synthetic anabolic steroid, the 17β-heptanoate ester of trenbolone. It has never been approved as a veterinary or human drug; the approved cattle growth-promotion implants (Finaplix, Revalor, Synovex) use trenbolone acetate. It is a potent androgen and anabolic compound with minimal estrogenic activity. Trenbolone enanthate has a molecular formula of C25H34O3 and a molecular weight of about 382.5 g/mol. CAS 10161-33-8 belongs to trenbolone, the free 17β-hydroxy steroid, not to the enanthate ester. It must be stored between 2 to 8°C and carries a Danger signal word due to its toxicity. Molekula supplies Trenbolone enanthate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
