Hi -   I just wanted to see if there are boys with DMD who are taking Growth Hormones and are still mobile.  My questions are:   1. Is your son GH deficient or not? 2.  How long has he been on GH? 3. Has his mobility changed at all since taking GH? Better or worse? 4.  Did you increase stretching daily and/or did you see increase tightness/contractures?   Thank you.   As you all know, all of thes…
