I got some quite bad gyno from a cycle a few years back which stayed with me for a long time. I went to the doc's and everything, and the end result was I was referred to a surgeon and was told they'd have to operate on it.
As a last resort, I got hold of some Tamoxifen and took 10mg a day for 3 months and the gyno reduced by about 80%. There's still a little left, but nowhere near what was there before. I'm taking the Tamoxi again at the moment, but the last little bit doesn't seem to be shifting.
It might not work for you, but if you can prevent surgery for $60 its worth it.
