Mike, I hadn't heard of it until now. I did a quick Google search of "Platelet-Rich Plasma study", and this one showed up. Maybe the results are something to heed.

Just passing along information, I don't want you to take it as personal criticism. If you go through with the procedure, I do hope it works for you.

FDA approval definitely isn't anything to have faith in, either smile .
