I also had a natural case of gyno when going through puberty. I had 2 pea sized lumps under each nip. Went to a cosmotologist and he injected them with something (to young to care to ask what it was) and gave me a scrip for some pills (again didn't care to know what they were). Between the two drugs they went away in about 5-7 days. But DAMN did that shot fuckin hurt. I wanted to kill the him.
He prolly gave me nolva or something similar and just injected shit to see how much pain he could put me in. Anyhow I haven't had a problem since. Sorry I don't remember what the drugs were.
