Hi
i have had prp a few times. The stem cells are put into your prp ( blood). Yes they screen the stem cell donor for various diseases and viruses but I think some inform is also verbally communicated. It is not a shady place at all. The word is that it can almost be affective as a fue. Im just concerned about the cancer ( tumor) part. I have heard some reults can be very impressive. Its weird there is very little info on it on the internet. There is One guy that posted is results on this forum. I'll see if I can find the link it looks really good
