I've seemed to have this for awhile but have never been sure whether or not it was gyno. It definitely seems kind of puffy and has been as long as I can remember since I was fat when I was younger (now 20). It seems like it mostly from the side with how much it comes out. I feel a bit of a lump underneath the nipple but no tenderness at all. In talking with my lifting partner he said he could feel a lump/gland under his as well but not when he flexes, I can still feel a bit of a lump when flexing. The other side to it though is that when i'm cold out of the shower, for instance, it doesn't really look like gyno at all and my brother who's always been leaner and never really worked out seems to have these "puffy nipples" as well so I can't be sure. It does look pretty very similar to the before picture here http://en.wikipedia.org/wiki/File:Impending_Gynecomastia,_Puffy_Nipples.jpg
I have not yet used AAS and my test levels are actually fairly low (~400ng/dl), not sure about estrogen.
1. Does it seem like gyno?
2. If it is, is there anything I can really do about it at this point besides surgery?
3. Does having some already from non AAS related issues , or even having what looks like it which may be the case, make me more predisposed to gyno from future AAS use and if so would a SERM still be able to completely take care of any new gyno?
