Peptide injections are everywhere — BPC-157, TB-500, peptide stacks for injury recovery. But here's the problem: there is almost no human data to support any of it. As an orthopedic surgeon, I'm breaking down exactly what the science actually says — and what it doesn't.
In this video, I review the biology behind BPC-157 and TB-500, how peptide therapy is being marketed to athletes and biohackers, and why the gap between animal research and human clinical evidence should make you think twice before injecting anything.
What you'll learn:
What BPC-157 and TB-500 actually are and how they work
What the real evidence says about peptides for tendon healing and injury recovery
Why the biohacking community is getting ahead of the science
The difference between experimental medicine and unregulated self-injection
Why peptides for athletes may be promising — but are nowhere near proven
This is not anti-peptide propaganda. The biology is genuinely interesting. But as a surgeon who operates on tendons and joints for a living, I have a responsibility to tell you what the human data actually shows — and right now, it's almost nothing.
