Can anyone with HGH experience answer? If you have one of the small 1.5 inch HGH injection vials with what is supposed to be 10iu of hgh powder in it how full would it be? If it is filled a half inch high with powder in it is that about 10 IU or more like 4 IU? Sorry, wierd question but someone is ripping people off I am just not sure how bad yet.
