Now I am not sure I have gyno. Hard to tell with me, But when I shrug my shoulders forward, I get the puffy look in my nipple area. Now if this is gyno, It is from many years ago. There is no senitivity or lumps I can tell. I was thinking of trying letro to see if this may reduce the puffy look in my chest and flaten the nipple area more and tighen up my chest. Could a short run of letro to reverse and fix this and should I run it with my next cycle to help reduce the chances of a estrogen rebound. I have lost some considerable weight and bf% is like 14-15%. So I am thinking this may be my next step. I am hoping that it can be a quick fix. Thanks guys
