What I hear from others, it should not be a problem, and I have never had an issue in the past, but on my most recent cycle, I did notice that after I came off, while the AAS were still lowering. I began experiencing pre-gyno signs that foced me to ramp the dose back up. Keep in mind, I was using over a gram of test and along with other steroids. I think that things wouldn't be quite as out of control on a more traditional dose of gear. Up to this cycle, I have never seen rebound, nor have I seen it in my guys. Still, I would plan to run adex right into PCT and then may even maintain a lower dose while in PCT.
