AI and HCG question

[The Deadlifting Dog]

hCG should be run on every cycle.
An AI should be run on most any any cycle that has steroids that aromatize. Only bloodwork is the true way to tell. We are not looking to crush estrogen or have super high estrogen. (people going into a show may want to crush estrogen)

During cycle, in which week should I get my bloodwork done to check my estrogen levels?
