Comprehensive Overview

Methyltrienolone, scientifically known as Metribolone or R1881, represents one of the most potent anabolic-androgenic steroids ever synthesized, demonstrating 120-300 times the oral anabolic potency and 60-70 times the androgenic potency of methyltestosterone in research studies. This synthetic estrane steroid is a 17α-alkylated derivative of trenbolone, featuring exceptional binding affinity for androgen receptors while maintaining virtually no estrogenic activity.

The compound’s extraordinary potency stems from its unique chemical structure – 17α-methyltrenbolone – which provides exceptional metabolic stability and receptor binding characteristics. Unlike conventional anabolic steroids, Methyltrienolone demonstrates significant affinity for multiple steroid receptors, including progesterone receptors (208% relative to progesterone), androgen receptors (204% relative to testosterone), and mineralocorticoid receptors (18% relative to aldosterone).

Methyltrienolone’s primary significance lies in scientific research applications, where it serves as the gold standard ligand for androgen receptor binding assays and photoaffinity labeling studies. However, its extreme hepatotoxic potential, observed even at doses as low as 0.1-1.0mg daily, prevented its approval for medical use and makes it one of the most dangerous compounds in existence.

The compound’s 17α-alkylation provides oral bioavailability but contributes to its exceptional liver toxicity, with severe hepatic dysfunction documented in clinical trials for breast cancer treatment, leading to immediate discontinuation of development.

Historical Background & Development

Methyltrienolone was first synthesized and described in scientific literature in 1965, representing a significant advancement in anabolic steroid research and development. Initially developed as part of efforts to create more potent therapeutic agents for muscle wasting conditions and hormone-responsive cancers, the compound quickly demonstrated unprecedented anabolic activity in laboratory settings.

Clinical investigations began in the late 1960s and early 1970s, focusing primarily on treatment of advanced breast cancer in women. Despite showing therapeutic efficacy and relatively weak androgenic effects, researchers observed severe signs of hepatotoxicity at extremely low dosages, with liver dysfunction occurring at doses considered minimal for other anabolic compounds.

The compound’s development for medical applications was permanently discontinued due to its unacceptable hepatotoxic profile, with researchers concluding that no therapeutic dose could be established safely. However, by the mid-1970s, Methyltrienolone found new purpose in scientific research as the preferred ligand for androgen receptor studies.

Its adoption as a research standard occurred because of its exceptional receptor binding characteristics and stability, making it invaluable for understanding androgen receptor function and developing new therapeutic compounds. Today, it remains widely used in legitimate scientific research while being encountered occasionally in illicit performance enhancement contexts.
