Mariah, let me clarify, my levels have been rock solid from day one, no change post op except my T went from ~30-50 down to below 20. For me T was always fully suppressed by estrogen alone, never needed an AA.
My initial dose had me at 700 (I misremembered the 750 number), when it was cut in half the level went to 350, exactly half. Cut the dose again and levels went to what I mentioned above so reduced by something like 40%.
