You dont know what an AI is?
You do understand that when you have abnormally high testosterone levels you in turn will have elevated estrogen levels?
This can lead to elevated blood pressure, fatty tissue gain and breast tissue growth.
Unless you do something to keep it in check your going to have a hell of a time trying to recover your natural test levels.
Because......your natural test wont turn back on when estrogen is super high. When its high the brain thinks there is too much testosterone.
When its low it thinks there is not enough.
Before you start PCT you want estrogen at least within normal ranges if not bottomed out.
An AI prevents the conversion of testosterone into estrogen.
