Ultima-MTREN 5 - Ultima Pharmaceuticals

First synthesized in the 1960s, Methyltrienolone is a potent oral anabolic steroid derived from trenbolone. Its structure includes a 17-alpha alkylation, enabling oral bioavailability but significantly increasing liver toxicity. Methyltrienolone is highly anabolic, with a binding affinity for androgen receptors far surpassing other steroids, making it a standard in receptor-binding assays. Despite its effectiveness in promoting muscle gains, its severe hepatotoxicity prevented widespread clinical use, relegating it to laboratory research to assess androgen receptor activity.
