I have researched this on a number of boards and can't seem to find a definitive answer. I'm hoping I can put this to rest here with you guys. There are people who say that a SERM is not required with epi, in fact, I have seem pictures online of gyno being eliminated using epi. It is said that because epi is anti-estro that gyno is never to be a problem. I've talked to a guy personally who used to do epi cycles without a SERM, only a OTC PCT, and he says he's just fine. Yet others, including a epi cycle FAQ which appears to be from the manufacturer of RPN Havoc say a SERM is required.My thoughts are that possibly because epi is anti-estro deeming gyno a non-issue, people assume a SERM is not required but maybe the SERM does something else a la test or some other function that is required to get a body back in working order post cycle? I'm 3 days into a 30/30/30/30 epi cycle. This is the first time I have done this, or any meds for that matter. I have Nolvadex on it's way in the mail from a research chem co, but I'm not sure if I need it. If I do need it, do I start it the day after I finish my cycle? I would appreciate some wisdom. Thanks.
