No. It will actually have the opposite effect. It will make your penis smaller. Also, instead of erections causing your penis to enlarge, HGH makes erections actually cause your penis to hide inside your body. In some individuals their penis decides to attempt to hide inside of their butthole instead of their scrotum. Oh and your ballsack will leak a highly corrosive black fluid. I have found that this black fluid can be used in place of kerosine powered outdoor lamps and BBQs.
