This sounds like it may not even be AAS related. If so, Nolva isn't the answer for sure. I have a buddy that dealt with this until his 40's (not an AAS user). He finally got the surgery last year and wishes he would have done it earlier. Poor guy was really self conscious about it prior to the surgery.
It probably doesn't matter what caused it. I just mentioned that because my friend was considering SERM's for life at one point. If you were cycling it would be different maybe.
