Is it an actual HARD lump of tissue behind the nipple? You may wanna try Rebound XT. Many here say to do HIGH doses of Nolva for up to two months but my friend tried REBOUND XT and it reduced it greatly, but it slowed up and after the first two weeks (maybe he should have waited) he tried the Rebound XT with 2.5mgs of Letro (1ml) of the liquid. He bought it from IBE and his gyno has continued to go down to the point that early in the day he has a tiny lump in only one nipple now, but it flares up towards the evening. He will run out of Rebound in like 2 days, so would anyone have any ideas on what he could do.....should he up the dose of the Letro....his biggest goal is to get rid of the gyno without surgery. Is it possible he might always have a small lump for the rest of his life and the best that the SERMS and AI's can do is reduce the size?
