As
@Just Fish said - we (male) care about Estradiol (E2) levels. Furthermore, it is mandatory that E2 is measured via "sensitive assay" method, at least what is highly recommended on TRT forums. I have never quite subscribed to that since the only difference between "regular" and "sensitive" is... the latter have lower detectable limit (3 pg/ml) which would be unlikely in otherwise healthy male.
The TRT mantra is - most male will feel good (but this is very subjective self-assessment) on E2 levels between 25-30 pg/ml. This is true for my self as well - when measured between 20 and 30, I don't have the "obvious" signs. E2 too low - depression, E2 too high - I am emotional like a little girl. By the way, have you noticed the majority of elderly (65 and older) man are very emotional? This is not necessarily because they are getting more wise, but because low testosterone production equates to less DHT (the main E2 antagonist) causing female hormones to run wild.
@miamifunk , on your question... as I said before, unfortunately "dialing" the levels cannot be achieved by any other means but testing (not cheap) and furthermore testing done in "scientific" manner. For example, i poopoed (sort of) my last test. While I was using Watson (50mg twice a week) 200 mg/ml for a long time, prior to my physical I shot UGL 75mg (250 mg/ml), T come back too high - above 1000 in the
day of the next shot. Not too bad, but apparently was well above the
day after the shot... So, now I plan to do two weeks 50mg/shot of the new suspension and go back to the lab.
If only the damn lab was closer (one hour drive on one direction), I would have measured every freaking day of the week to see the trend - there is a lot of talk about "saw tooth" pattern of T levels based on frequency and method of administration.
Bottom line, listen you body and test, test, test. Two weeks on your regular T shots and 0.25mg AI, record how you feel on journal, test Total, Free and E2, record as well. Adjust AI if you feel you need to, test after another two weeks, record and compare.
It has been a week since I started AI again and, breakouts on my back have began diminishing and did not shed a tear during the national anthem during MNF.
