High estradiol

[NotHuman]

That’s a fair point.The funny thing is I get the joint pain from primo and not from aromasin and others get ED and low libido from it even with good e2 numbers.
Shbg is another one that is hard to keep in range with primo.
You look like you know what you are doing and I am not arguing against your choice just pointing out why someone might use the ai.

Yea I think the debate is valid and we can't definitively say for sure which is safer. But I do know primo builds muscle, while an AI does not, so that's a pretty big advantage.
