Ok guy am lost on this one so am posting it here to get some opinions from the vets, I have a few friends that I help with their AAS use by making suggestions and twicking their cycles to keep them safe, one of the text me this morning saying that his left nipple started hurting a lot a few days a go and now it was turning black and that it was so bad he could not even take a shower so he put a couple of bandaids and it helped with the pain but when he try to change them the areola pealed off exposing raw flesh, my answere right away was go to the doctor, he got an appointment set up but I still not sure what can be causing this, he is on Tren A, Test A, Dbol and Var and running aromasin and caber so everything should be in check, he doesn't have any lump under the nipple just an extreme tenderness, could it be that the the pain and tenderness where from his lacting glands and by putting on the bandaids the moisture caused it? Any in put will be appreciated.
