People are looking for an alternative to M-drol and all other superdrol products that were banned in 2012. Msten is here to save the day. When dosed properly results have shown to mimic SD products. The problem with all sd products beside the harshness on the liver is the conversion to estrogen. Msten by Assault Labs has no conversion to estrogen and provides its users with solid size and mass gains. 

This is a solid product with solid results. 



As a dietary supplement, take 2 capsules per day in divided doses of 6-8 hours apart. Do not exceed 4 capsules per day.

Recommended Dosing:

Due to the extreme potency and toxicity of using methylstenbolone, we strongly advise all our customers not to use the compound methylstenbolone for any longer than 4 weeks.

Methylstenbolone is usually ran anywhere from 3-4 weeks (21-30) days, and dosed around 4-16mg per day.

We recommend that you take 2 caps spread throughout the day, once upon rising and once before sleeping to ensure best results.

We also recommend that you take a liver support supplement as well as on cycle support supplement.
