Out of control estrogen
Ty, I feel your concern with the E2, however, let's look at it a little closer ... Couple of things .. Was this a Sensitive or Ultra-Sensitive assay? Either way, can you post the reference ranges?
Even if this is based on a Sensitive assay, you can get this under control relatively quick, and without having to go overboard on the AI's! For starters, I would immediately look at breaking up the test dosage to 2x per week, which will reduce the spikes that could be causing higher E2 conversion.
Do you know your free & bio-available test level? Everyone is different, but for me a 1075 serum level is way too high for sustaining a healthy protocol. Again, that's "me", everyone has a zone that works for them. For me, the best balance seems to be in the 600ng to 700ng/dl range +/-, but I also naturally have a free test level in the 3.3% range, so that factors into the plan I have with my program.
How do I know this range is good for me? Well, for the most part I feel pretty good at that level, but it's also the area where I can feel the best and NOT have any real sides you see attributed with elevated testosterone, including the need to control E2. I haven't taken any AI in years.
