Why different recommendations starting AI?

You should already be taking an AI so, unless your cycle is finished, it is not to late.

You need to be taking an ai. I recommend taking it from the beginning. I waited to take it on my current cycle and within a week I had symptoms of gyno. I believe over time I have become more sensitive - not sure if this is common but in my previous cycles I felt like I was good, waited to take an ai, or took a Low dose and experienced slightly elevated estrogen. Now If I wait I seem to get gyno symptoms fairly quick... it started with just itchy nips, then sensitive nips, now it’s just a small lump that forms of my e2 is high. Luckily for me it’s gone away, but I know now that I will grow titties if I don’t control it.

It’s just better to take it, and personally, I’d rather crash my e2 than deal with Gyno. Just stick to arimidex, unless you have problems then I would go the aromasin route but that may not be necessary.
