I've ran 2 partial EPI cycles and had to stop both around week 4-5ish because for some reason it made me feel like crap. So before I ran these I searched the board but never read anything like my issue, in fact most users say it makes them feel good. So I got thinking about EPI having anti E properties. Is it possible my E could be dropping far enough to make me feel like that? Basically it's good at first but then I get very lethargic, no motivation and my strength seems to fall off. So I'm wondering if I need a little test to combat low E if that's my issue?
