Now that I run an AI I was still surprised to find out my E2 was at 300 not too long ago. So, not only is it important to run an AI, but it is important to get blood work done (E2 test is $45 here) to make sure it is used correctly.
Great advice by JV. A lot of young and new guys believe an AI is only needed to prevent or treat gyno. Increasing estrogen can cause so many problems far greater than man boobs and your vanity won't matter if you stroke out.

It just doesn't make sense to manipulate your testosterone and not control your estrogen.
