Here, Nandi just posted this and I read it with this thread in mind:
"I would not use arimidex post cycle as I believe it will suppress SHBG, slowing recovery of total testosterone, the ultimate marker of how recovery is progressing. Aromatase inhibitors could lead to the accelerated development of atherosclerotic plaques as well. Not worth the health risk and potential impediment to recovery."
Again, that was posted by Nandi (the admin at CEM).
