It's great to see people thinking. :roll:
If you have surgery to remove gyno, the chances of it coming back are greatly decreased. I've read many stories about people having gyno removal surgery in only one side of their chest. These same people then run many cycles of steroids, get gyno again, but only on the side that did not have gyno removal surgery.
All that to say, gyno surgery will permanently remove gyno in most cases, even if you keep using what gave you gyno in the 1st place. Though, if you have a bad Doctor and he leaves some gyno in place, then, yes, you can definitely get gyno again.
