I took 25mg of clomid ED for 7 months. My total T went from 477 to 1202 - top of the range. Docs were impressed. Great responder, they said. SHBG and E2 also went up - way up, out of range. But no benefit at all with symptoms.
I am an anastrozole over-responder. However, in this case, anastrozole didn't bring even bring E2 down at all - because the estrogen is intra-testicular.
25mg/day is not an unusual prescription.
You're woods are soft because of really high E2 which can't be managed with AI.
I didn't taper off clomid - just stopped cold turkey, which I think was a mistake. My Total T bounced back but my free T did not bounce back at all. You want to look into tapering off clomid.
