What is Methylstenbolone?
Methylstenbolone (2,17α-dimethyl-5α-androsta-1-en-17β-ol-3-one) is a potent 17α-methylated anabolic-androgenic steroid with high AR binding affinity and no aromatisation. The 1-en double bond combined with 2-methyl substitution confers exceptional anabolic potency.
Research tool for high-potency AR agonism, anabolic:androgenic selectivity studies, and comparative 17α-methyl AAS pharmacology. Research use only.
