depends on the type of gyno,, i got gyno from high prolactin levels which is above teh nip adn u can take b 6 600 mgs a day for a week adn that will reduce it , adn u can take nolva adn anastro. when i stop takeing sauce all my shit will disipate and go away wioth time, but there is some gyno that will not regress, my friend gots this huge bitch tit,, when ever we go to teh pool and he gots his shirt off im like wtf,, bro u need someone to suck on that bitch or what.... and he took sus a couple years back but he is so in denial that he thinks he had it before he even took the sauce, but there is no way for that and sus is a gyno causser from what i know,,
