Thoughts on improving therapy: 1. Adding rHgH as it is a known agent of chondrogenesis and causes chondrocytes to respond to IGF-1, one of the growth factors in platelets. Suspect that though HgH is a fragile molecule whatever mechanical forces it experiences in the syringe mixed with PRP would be less than those experienced in the knee. Thoughts, Irentat? The issue I brought up was regarding mixing HGH with anything within the syringe. As far as I know, there is not available information on what will or will not break down the very fragile HGH molecule so don't mix it with things like B12 or something similar.2. Suspect non-weight bearing is important for optimum results: Dr Dunn requires non- or reduced weight bearing of his patients. Irentat, you say you've had great results without rest. How long have you been getting PRP? How many injections altogether approximately? What exactly are you receiving treatment for? Do you mind me asking what the costs are for your HgH injections? (Forgive me for not researching this but I'm in a bit of a hurry trying to put this post together again after it disappeared.) I got HGH shots initially and moved to PRP (2 each in each ankle) around Dec-Jan timeframe. I am getting treatment for cartilage degradation. Almost complete denuding of the joint but now focusing on rebuilding the ligaments, which originally caused the issue.rHgH in Australia:Only available as a government subsidised medicine for a small number of conditions, e.g. childhood growth disorders. Research so far suggests that it can be prescribed for other conditions but without the subsidy resulting in a cost of approximately $1300 for 24mg or 60 IU (according to Irentat's calculations). The brand is Humatrope by Eli Lilly. My chemist is waiting to find out whether he is able to fill a prescription for it. Says orders go directly to Eli Lilly. I am aware of rHgH being prescribed here for use as a rejuvenative in HRT (Hormone Replacement Therapy).I'm sure I've missed something. Will address NikkiE's question via private message.
