Methyltrienolone

Methyltrienolone (also known as R1881) is a potent, orally active anabolic steroid which was never marketed for medical use but has been widely used in scientific research as a hot ligand in androgen receptor binding studies, as well as in studies of the effects of androgens on the body.

Chemistry

Methyltrienolone is a synthetic and orally active anabolic–androgenic steroid (AAS) and a 17α-alkylated nandrolone (19-nortestosterone) derivative. It is closely related to trenbolone, a well-known AAS.

Pharmacology

As an AAS, methyltrienolone is a agonist of the androgen receptor. It has a high affinity for the androgen receptor and binds with it to produce its effects. Methyltrienolone is one of the most potent AAS produced, with both high anabolic and androgenic effects.

Side effects

Methyltrienolone has a number of potential side effects, many of which are common to other AAS. These include hepatotoxicity, cardiovascular damage, changes in mood and behavior, and effects on the reproductive system. Due to its hepatotoxicity, it is not recommended for use in humans.

Research use

Methyltrienolone has been used in scientific research as a reference standard for the androgen receptor. It is often used in studies investigating the effects of AAS on muscle growth and strength, as well as in studies of the effects of AAS on behavior and the brain.
