Methylstanbolone 10mg


What is methylstenbolone? Methylstenbolone is a new and potent prohormone designed to build serious mass and increase strength for bodybuilders and athletes. Msten contains 4mg of Methylstenbolone making this product great for extreme muscle gains.

What are the benefits of using methylstenbolone?

The benefits of Methylstenbolone include:

  • Mass Gains
  • Size Gains
  • Bulking
  • Fuller Muscles
  • Strength Gains

Now that Superdrol is banned many people are using Methylstenbolone as a replacement. This is because it provides the same type of results and gains that superdrol did.

Does methylstenbolone Convert to estrogen? Methylstenbolone does not convert to an estrogenic metabolite or have any affinity for the progesterone receptor, so estrogen mediated side effects should be virtually non-existent. This is big news in the bulking and mass building prohormone world.

Is methylstenbolone Toxic on the Liver? Yes, methylstenbolone is a toxic substance due to its ability to resist metabolization, although anecdotal reports lead us to believe it carries less side effects than superdrol. One has to use on cycle support (liver care) when taking methylstenbolone and a good PCT at the end of your cycle.



If your looking to get serious results grab a bottle of Msten Mass builder today!

  1. Good product, no negative sides 4 Star Review

    Posted by on 21st Feb 2017

    First time I've done a prohormone cycle, body weight up 11 lbs, max weights up 20%+. Gained 4" on chest 2" on biceps. I'm taking organ shield and have my PCT ready for when I finish. Overall very happy.

  2. Very unique androgen 5 Star Review

    Usually stuff with a high anabolic rating that is 5a-reduced is only good for cutting but this is basically good for anything. stacks well with other PROs or can be used alone.
