I've been taking 3 iu's of HGH for the last 3 months. When I moved up to 4 iu's a day I noticed that my nipples got sore and yesterday I noticed a small bump under my nipple. I've heard that most gyno while on HGH is caused by prolactin and not estrogen as is common with AAS.


This brings my to my question. If I needed to test my estrogen and prolactin levels whats the way to look for a testing lab? I'm going to stop taking the HGH for now but I want to continue and unfortunately I cant do so until I figure out if its estrogen or prolactin that I need to fight.
