The Peptide Surge: Hype vs. Evidence
Peptides are having a moment, but between the hype, the celebrity mentions, and the DIY internet forums, it’s genuinely hard to tell what’s backed by real evidence and what’s just noise.
In this episode, Dr. Miranda Naylor talks with Dr. Jeff Gross, a fellowship-trained neurosurgeon who spent almost 30 years treating neck and back problems before moving into regenerative and longevity medicine. Jeff started using stem cells, exosomes and peptides to help patients stuck between “not bad enough for surgery” and “nothing else is working.” It eventually became the focus of his practice, Recellebrate. Now he helps patients use these tools to support healing, muscle, skin, and long-term health.
We’ll explore:
✔️ What “FDA-approved” actually means and why it has nothing to do with whether something works
✔️ Why peptides have surged in popularity right now (and the role distrust in Big Pharma plays)
✔️ The real evidence base behind peptides, and why the big randomized trials don’t exist
✔️ Jeff’s favorite peptides for muscle, skin, and longevity, and how they pair with GLP-1s
✔️ The truth about where peptides are sourced and how to make sure yours are safe
✔️ Stem cells vs. exosomes vs. peptides, and when to use each
✔️ Common myths and misconceptions that keep people from trying these therapies
✔️ How to find the right clinician if you want to explore this path
If you’ve been curious about peptides but weren’t sure whether to trust what you’re seeing online, this conversation should clear a lot of it up.
