My friend and I both have gotten slight gyno under our left nipple. We are not doing anything major that would cause this. We both do 200 mg test cyp a week 100 mg primabolin a week. Done this for years with no problems. Introduced mod and ipamorelin into the picture and I now have a small kinda soar lump. My buddy also did melonatin 2 for for tanning and he has a lump. I have read several questions regarding the possibility of peps doing this with no real clear answer. Is there one? I can drop the peps and see what happens, really like them but probably the only way to tell. If it goes away guess that was it. Can't see how peps would affect my test to estrogen balance though.
