I have gotten gyno, had it removed, and have it slightly again, so I consider myself an elite as far as experience with it. You have slight tissue under there, but that is normal for all guys. I would not worry about it unless you feel it is getting bigger, at that point I would do some nolvadex. If you do steroids your going to get it to some degree anyway, whether or not you do antiestrogens. Plus what looks normal now, may not look so normal overtop a massive chest, as that tends to make it appear worse. If your worried then buy some nolvadex and keep it on hand, and if u feel like it is developing (at this point you don't have anything really) then start popping some antiestrogens.
And for god's sake, get your ass in the gym!!!
