FSH stimulates aromatization

I've been on HCG monotherapy for a while now, and my response has been much better lately than it was years ago. E2 has always been an issue with HCG. In a recent lab, my TT was over 1000 ng/dL, while my E2 was around 65 pg/ml. I tried to control my E2 by alternating 780/500 IU of HCG EOD...
