berfore trt my estradiol was at 18 which is kind of low, but it was due to low test. anyways i began trt at 200mg/wk split mon/thurs. by week 4 my estradiol was in the 70's. So it may only take a couple weeks to climb back up, but everyone is a little different. no ai was taken btw and hcg was dosed same as you.
May i suggest not dropping the adex alltogether and simply lowering it? my reasoning is that instead of letting your e2 shoot up then have to reconfigure your dose to play catch up, you could slowly lower it and let your e2 slowly rise and then stop once you find the right dose. either way, best of luck!
But how did you feel with E2 in 70's. One guy on here said he feels good with it that high.
