im doin 500 every 3rd day not sure if its kicking in or not, in the past (this may be weird but happened to a friend too) when I had been on shit a while one of my nuts would kinda suck up when I had to take a shit, than when id do the hcg it would drop back down and never do that again, but I used to take the hcg all at once usually 2500.... Also while taking a shit I have got cramps in my taint, hasnt happened this whole cyc till last week..... worst cramp ever
