All of the SERMS come with crapload of bad sides (decreasing of good cholesterol, possibly developing tumors in the future, etc) plus when you buying it online you don't know if you're getting real stuff or fake. I know one can use 6-bromo or 6-oxo AI 's. But is there anything out there that would work just as good as SERMS when it comes to Estrogen control as part of PCT. I am planning to run Epistane cycle 10/20/30/40. Thanks in advance for your input.
