Hey I have been reading a bunch lately on gyno and from what I've read it starts with pain in the nipples and then you form a lump behind the nipple. I noticed a lump forming on my last cycle of test prop and tren at 100mg/day of both while taking arimidex at 1mg/day. I went off of the cycle it went down. Now i'm on 500mg test and 600mg of deca and the lump has come back full force. I'm taking caber at 500mcg Mon thurs thinking it could be progesterone related. My problem is the lump is not behind the nipple at all it's to the side of it. If I touch the nipple i feel nothing but as i go to the outside i can feel a lump and it's not circular it's more of a hot dog shape. It's really weird and not sure exactly what it is if anyone has any ideas such as gyno that is just forming weird I was on 1mg/day of arimidex and now I'm on 2.5 of letro for the past 2 days. Sorry for the long post but any help at all is massively appreciated.
