Do I understand? You are NOT following a TRT protocol. Yet, despite this you have high estradiol. You assert that you know this based on water retention and a non-sensitive, estradiol test. You aren't using an AI, and haven't at any point - even when you are injecting testosterone. You invited comments. Is this essentially your situation?
I will only note that practitioners in the field of androgen replacement feel that the non-sensitive evaluation of estradiol is of no value for men. It over-reports the serum levels in most, under-reports in some...frankly it tells a doctor and patient nothing about where E2 levels actually are. Your belief that you have had high estradiol may be true, you certainly believe it is, but in the absence of a sensitive test the most any of can do is say, "maybe." Which is all that a good doctor can really add as well.
But if you are as symptom-free as you claim, it shouldn't be a problem. Each of us is different and only a good doctor can dig in deeply enough to determine why you post higher values...if you actually do. What lab test you run is up to you. But if you are seriously following and managing serum levels you'll find a more robust discussion if you use the sensitive test.
