Stem cell injections- regenexx vs ROW

I only offer PRP at this time not stem cell. However, I noticed that the regenexx people don’t just perform a single stem cell injection they do a series, so some kind of growth factors/nutrients a week or two before the actual stem cell injection. Is there any significant evidence of benefit for the other injections beside the actual stem cell injections? (I realize that the stem cells themselves are not completely “proven” either for peripheral joint OA)
