Methyltrienolone is discussed as an extremely potent strength-and-muscle drug. Also called R1881, it is actually best characterized as a laboratory androgen, not a tested bodybuilding medicine. Receptor potency does not tell us how much size or strength a person would gain. Liver injury and an unknown human safety margin are the main concerns.
Human-tissue binding studies confirm high-affinity androgen-receptor activity, but controlled human efficacy and safety trials are absent. Hepatic risk is inferred from its oral 17-alpha-alkylated structure and the AAS liver-injury literature.
Potentially severe cholestatic liver injury, adverse lipids, gonadal suppression, androgenic/behavioral effects and cardiovascular harm; true human dose-risk is unknown.
Liver panel and symptoms of jaundice; HDL/LDL/triglycerides; blood pressure; CBC; reproductive hormones. Testing cannot establish a safe exposure.
Never approved for human use. It is mainly a laboratory reference androgen, not a medicine.
