C1-2 prolotherapy

Check out this video. Through some late night internet research I went down a rabbit hole and stumbled upon this guy. Perused his clinic website and apparently he trained under the father/founder of prolotherapy. He also does a lot of PRP and stem cell injections as well. Anyone see anything awry in this video? I mean how on earth does he know where he is when only using lateral? Seems dangerous no?
