Does regenexx stem cell and blood platelet procedures really work? i'm getting my first injection next week for my mild labrum tear in my shoulder

Hopefully: A small labral tear can potentially heal on its own, or it also may not. The injection of stem cells, platelette derived growth factor, or other " growth factors" has been tried for several years; with variable results. The good thing is it is relatively safe, and hopefully the tear will heal. What is not clear if the cells or growth factor was any benefit; but again hopefully you will do well.
