I've been seeing a lot of activity elsewhere with people posting things about using an AI is inherently bad with some agreeing and some disagreeing. I'm not sure I've seen any direct studies that support their conclusions. I'd think that if your estrogen/E2 is extremely high then you'd need an AI to get back into range but don't go so far that you go below range. If you test in the middle of the range for estrogen then you probably don't need an AI. What are everyone's thoughts?
