What is Methylstenbolone?
Methylstenbolone (M-Sten) is an oral, 17a-alkylated designer steroid from the prohormone/designer wave of the 2010s. It is very potent and delivers dry strength and mass gains without aromatization but, like all 17a-alkylated orals, is markedly liver-loading.

How it works
Methylstenbolone activates the androgen receptor strongly and does not aromatize. Gains are dry and hard, the side effect profile harsh in line with the high potency - especially liver and lipids.

What the research shows
As a designer steroid there are hardly any controlled human studies. The AAS pharmacology (Kicman 2008, Hartgens & Kuipers 2004) classes the properties of oral 17a-alkylated steroids.
Side effects
- Liver: 17a-alkylated, strong - short cycles, liver support.
- Lipids: marked HDL lowering.
- Blood pressure rises.
- HPTA suppression - PCT topic.
