Methylstenbolone is touted as a key prohormone to get your hands on if you’re aiming to up the ante on your strength, size and mass.


Its chemical name is 2,17α-dimethyl-5α-androsta-1-en-17β-ol-3-one and is classified as an anabolic steroid. This means that although Methylstenbolone is quite different to most anabolic steroids in the business given its composition and mode of dosing, it will still promote positive results when you’re being tested for steroids.

Besides being called “Methyl Sten,” this prohormone is also dubbed as “Msten” and “M-sten” by users.  Moreover, Methylstenbolone is considered as the safer and more user-friendly alternative to Superdrol. It is fast-acting and users can already see results after a couple of weeks or so. Interestingly, lean muscle gains up to 25 pounds in the span of 4 weeks have been logged for this compound.



Let’s check out the benefits that Methylstenbolone brings to the table when you cycle with it:

  • Boosts strength levels
  • Helps promote the development of fuller muscles
  • Bulks you up without the risk of retaining excess water in the body
  • Considerable size and mass gains


Based on logs provided by Methylstenbolone users in bodybuilding forums, here are some specific results that you can expect when you include this prohormone in your arsenal:


Bulking: It is possible that you can gain approximately 15 to 20 pounds of lean muscle with a daily 10mg dose of Methylstenbolone for 4 weeks.This prohormone has become quite an icon in the bodybuilding world for its ability to promote serious mass.


Cutting: Users report that they were able to get rid of as much as 3% of body fat while packing up to 6 pounds of muscle when they took a daily dose of Methylstenbolone in 4-week period. There are even reports of users achieving up to 20 pounds of muscle gain during cutting in the same time span.


Re-comp: With a daily 10mg dose of Methylstenbolone for 4 weeks, users tip off that they were able to eliminate as much as 2.2% of body fat while gaining 6 to 11 pounds of lean muscle.

However, it is still important to take note of your diet, alcohol consumption and genetics while cycling with this prohormone, since these factors can easily make or break your chances of realizing the results that you’re gunning for.
