Ok so you have been taking epi for a couple of days at 20mg, there are a lot of guys that don't even have a pct for epi cause it's mild. There are a lot of issues out there that you read about and everybody reacts different to pro's, supps, etc. I like to take precaution and use an on cycle and a proper pct just for my own piece of mind. Nolva/tomix citrate is a good serm. I would put a test booster with it. It's up to you to continue with the cycle. Just watch how your body reacts to your cycle. I know reading some of this stuff can get a little discouraging.
