I bet it's not a gyno...
I notice ends of my nips are slightly bit larger, but no lumps. they are slightly bit noticible through the t-shirt... I was paranoid... I'm still running 500 Omna, don't use anti-e, but have Nolva on hand. I went to see doc (my insurance covers partially gyno and cosmetic shit) and NO, it's not GYNO...
All he said that when you get off cycle, goes away (what I described above).
You didn't give much info, bro... Are you on the cycle? What are you running? How long have you had this?
did nips appear that way sence you started working out?
Soon,
