Every athlete seems to get PRP or ‘stem cells’ these days — but does any of it actually work? In this episode, the Boneheads dive head-first into the world of biologics to separate real science from medical mythology. We break down what PRP actually does, why most ‘stem cell’ treatments in the U.S. don’t contain real stem cells, and what’s really happening inside those expensive international clinics promising to ‘regrow cartilage.’

We look at the evidence by injury, roast the $10,000 cash-pay clinics selling hope in a syringe, and explain why your favorite NFL player didn’t actually heal overnight — even if ESPN said he did. If you’ve ever wondered whether these treatments are miracle medicine or just really fancy orange juice, this is your episode.
