Methylstenbolone, known by the nicknames M-Sten, is an orally active designer steroid. Chemically, it is a 17α-methylated derivative of dihydrotestosterone (DHT).

It was never introduced for medical use but was wildly popular among internet retailers falsely marketing it as a supplement. It was brought out post 2012 ban and released initially under the trade name “Ultradrol.” Ultradrol was 4mg a capsule with 8mg being considered high. I would say 20mg is the limit most people would want to consider researching.

Real world application wise, it’s very good compound. And it is close to superdrol with the only difference in the two is a double bond at the 1 position! There is a slight bit of water retention but not as much as superdrol. Also, M-Sten never felt toxic to me, nor came with the very common lethargy of Superdrol.

It’s been a VERY long time since I played with this but I remember it being a good compound and seeing excellent strength and vascularity after exceeding 10mg. Methylstenbolone doesn’t stimulate the progesterone receptor or convert to an estrogenic metabolite when synthesized by the body.

I think M-sten got overshadowed by many other more harsh compounds back in the day. Mainly, because many didn’t utilize an effective dosage or had a negative experience because they purchased a product which was multi-compound stack as most reported cases of bad sides came from products that contained DMZ as an added compound.

MSTEN has recently made a comeback from a few research chemical companies. One of those companies happens to be our good friends at Amino Asylum.
