though it blocks about 65% of the estro build-up, it does little to stimulate the HPTA (like clomid & Tamox (nolvadex) are purported to do). Clomid & Tamox are both SERMs so they don't keep estro blocked after you stop taking them (talking about nolva specifically) but the point of running aromasin on cycle would be to have no rebound effect so the nolva doesn't have to take that responsibility on. I read that Clomid & Tamox stimulate the HPTA precisely by somewhat blocking estro build-up (at least in certain tissues). So one might thing if that's the case why not aromasin for pct? Pause for thought...
IF blocking estro is what kicks the HPTA back into gear then it seems to me a real AI would be much more effective for PCT. But, it's not needed overall to stimulate HTPA and the two SERMS will block estro anyway so nolva and clomid work synergistically to help you recover. Aromasin is not needed but can help blocking estro which can i guess help with recovery but will not work at starting back HTPA as fast as both would together.
