over the summer I got tested for gyno because during puperty my nipples started to get puffy and lactate and Wouldnt go away, so I saw a doctor and he said I didn't have it. Last night i tried to see if i could still lactate and started to squeeze my nipple and dark brown discharge came out which is weird because its always been clear. I was wondering if s4 or gw could cause this because those are the only 2 products I'm taking as of right now. I'm a little scared because some people are saying it's a sign of Breast cancer. I also just finish taking lgd 4033 and anamorellin last week but I only took them for like a month.
