Ok I would say Ive read quite a bit on estro and AI's and how they work in general. I know AI's duty is to bind to the aromatise enzyme making it useless and preventing Test's conversion into estrogen. But let's say you already have high estrogen levels (disregarding cycels here) before you start taking an AI. What happens to the existing estrogen? I guess what Im asking is does the AI just basically inhibit any future conversion of test into estro? What about ridding the body of existing estro, does the AI take care of this to, if so how?
