I have a lady friend, that was taking some hgh. 1/2 an i.u. twice a day. a total on 1 i.u. a day. she was doing this monday- friday for about 3 wks. she then stopped, b/c the guy that was giving her her shots went out of town. so noticed almost the next day that her joints were beinning to ache. so discontinued the hgh. it has now been a bit over a week and her joints are still hurting her badly. does anyone know why this is? did she take 2 high of a dose? does anyone know how long her joints will continue to hurt? thanks for any help!
