@ 375mg of Testosterone per wk, I wouldn't worry about an AI @ the moment, you say your not feeling any sides. If you get any sore/pain in your nipples,you have Nolva on hand,correct? Best SERM for it..I would go 5 weeks and get Labs, see were your E2 is, some estrogen is good for you....And YES, run HCG on cycle..GhostProfit
