Im 19 and around 7 months ago i started developing puffy nipples or gyno. I've been working out 4 times a week over the past two years and have never came into contact with steroids. Due to my lack of energy i decided to try a Testosterone Booster from GNC, it worked quite well and nothing seemed to be going wrong. I only used the booster for around a month and then stopped, 4 months later i started noticing that i was developing a lump under my nipple which has made it stick out around a quarter of an inch.
My nipples are not sensitive but once in awhile they itch a little bit. I'm not sure if the Booster would've been the cause of this because of the time frame that elapsed before any noticeable symptoms appeared.
What should i be seeking to do? I showed my doctor but he was unconcerned because the lump under my nipples are not easy for him to detect.
Thanks.
