Will trenbolone acetate in the presence of methanol yield trenbolone acetate if distilled water is subsequently added thereafter?
The method will not convert trenbolone acetate to trenbolone, the ester is not cleaved under these conditions.



It is however possible to separate the steroid from a mixture with other, water-soluble compounds this way. 

Unless you are a veterinarian and use trenbolone or its acetate as a growth promoter for cattle, you might want to consider the legal situation in your country. As far as Germany is concerned, the possession of as much as 2 g might lead to real trouble. Here, the non-punishable, non-significant amount is in the 150 mg range (for its use in sports).
