My E2 went from 31 to 55 while I was on a 3.5 day injection schedule. I wanted nothing to do with an AI, unless it was a last resort, so my doctor and I went to a daily injection protocol. I had been injecting 60mg every 3.5 days. I have been administering 16mg every morning for 15 months and my estradiol sits between 25 and 30. I have a total testosterone value over 1000 on 112mg a week/16mg a day.
I am am very lean, no reason to suspect excess conversion due to high body fat. Did your doctor discuss more frequent, potentially smaller injections, more frequent and smaller than you're working with now?
Even with that super high estradiol, don't forget how potent Anastozole is. A little can go a long way.
