I am looking for some feedback on whether or not their is any difference between the 2 supplements. I ran 11-oxo at a rather high dose last summer and for the first few weeks got decent results. My problem was I suddenly started to experience the worst panic attacks and anxiety I ever had. I had to stop the cycle because every day it felt like I was dying. When I stopped 11-oxo the attacks stopped. I am curious if I try 3-ad would i experience the same attacks.
