Ultra sensitive tests. The 90 e2 was unmanaged and the one in the teens was taking too much AI. To keep it in the 20-30 range intake 1/2 of an Aromasin pill weekly. However, I recently lowered my Testosterone does from 40 mg E3D to 34 E3D in an effort to keep HCT and HB low but I also stopped taking an AI and will see how it goes. I also take 50 mg of Nandrolone along with each shot.Good post. Work your e2 range in teens to 90s, was that an ultra sensitive test? Also, do you always take aromasin or what is your protocol for that? Thx.
