In my opinion each person has kind of an individual level at which the aromatize at and then it rises from there. It’s probably more of a curvilinear response on a graph. As long as you can keep it below that threshold you are good. Obviously total dose matters as well as frequency as well as your response.
Here’s some examples from my own trt . 100 mg once a week and my estrogen is high >100, even with 0.125 of adex. Also test peaks, converts to estrogen so test is dropping while estrogen is rising, makes it hard to achieve and stay at a 20-40:1 ratio of T:E.
Split it into twice a week and it’s better , still need the low dose adex though
If I go to MWF though I can easily run 120 mg without any ai.
Daily is fine/better than 3x weekly but may not be needed at reasonable TRT doses unless someone was a truely excessive aromatizer. At above trt dosing (300-400 mg+). I could see daily dosing being a very substantial benefit.
Don’t get me wrong, even with trt daily pinning is better, it’s just the question of if it is truely necessary for most people if their labs are in range and they feel good
