my gf is really short (5 '1) and shes 20 years old. She was thinking about running gh for a few months and see if it gives her some height. I was wondering how long would she have to run it to see some results. And whats a good dosage and are there different types of HGH i know there are blue tops im not quite sure what that means.... thanks and if she has insurance can she get it from the doctor?
