I would not assign a number threshold for when to introduce an AI. Guys respond differently to different levels, as well as total androgens relative to estrogen being part of the equation. I understand you’re trying to convey that he shouldn’t just take an AI if his levels aren’t too high on paper, but people are going to read that and take your advice out of context as hard ideas on ranges. People use wildly different stacks and feel very different at different estradiol levels.Well, you have two choices. You can take an Ai or a SERM. Or add mast. If your e2 is high, above, idk, 55, ... I would take an Ai, if not, I would take a serm. Is test all that you're taking? Or is dhb still in the game? The more dht's you have, the more estrogen you need, as it's neuro protective.
Also, amounts of DHT derivatives used are not linear indicators of actual DHT levels, by any means. You don’t need more estrogen in the picture just because you added DHB. Now if you were going to say he should probably consume more choline, I can get behind that.
