This is why Aromasin should be used during PCT, not adex. Aromasin prevents estrogen rebound, as it is Type I steroidal AI, or a suicidal inhbitor. The aromatase enzyme which Aromasin binds to is permanently deactivated. Adex along with Letro are Type II which work great on cycle, but not during PCT. Once the cessation of a Type II AI occurs, you estrogen most of the time will bounce back.
If you feel that you are experiencing rebound, run aromasin @25/25/12.5/12.5 for 4 weeks. This will have the added benefit of raising your natural test levels as well.
