Nothing but respect for you man, here's what I've taken note of so far.

I'm retaining water, so much so that my friends have noticed i'm getting "bigger."
My sex drive is wayyy the funk up.. as in calling old gfs etc...
and then the euphoria...
gained 7lbs
acne

I definitely feel "on" something, so I've ruled out placebo. I'm guessing I'm an early responder in the beginning stages of a cycle, blah blah blah.... even if we have to go the hypothetical route, that'll do. So you say it evens out in the middle?
