From my understanding.... masteron, winny, and proviron all have anti-estrogenic effects but they are very very mild and should not be relied upon. A bottle of A-dex or letro will be much much cheaper than taking masteron for anti-e purposes.

The reason we don't hear a lot about masteron is because you "generally" need to be under 10% body fat to see the effects of masteron..... not a lot of people want to spend the money for a compound if they aren't going to "see" results.
