Dr. Leigh Baxt: The Peptide Craze
About this episode
This episode explores the science and safety concerns surrounding peptides marketed as health enhancements.
Peptides are being sold online as miracle fixes for energy, healing, and longevity—but what if the science behind them is shaky, or even dangerous? In this episode, Therese Markow and Dr. Leigh Baxt pull back the curtain on the peptide craze, revealing what we really know (and don't know) about these heavily marketed "biohacks." They discuss the complexities and risks of unapproved peptides, which are often marketed for health enhancement. Dr. Baxt explains what peptides are and speaks to those drugs that are FDA-approved, like GLP-1 agonists and insulin, but also highlights the safety concerns of unapproved peptides, such as BPC-157 and TB-500, which lack appropriate clinical trial data and are often synthesized in unregulated labs. Dr. Baxt emphasizes the importance of proper clinical trial processes and regulatory oversight to ensure drug safety and efficacy. Key Takeaways: A peptide is just a short chain of amino acids. They can be created synthetically, they can be isolated, and they are natural. The body doesn't care whether a peptide is "natural" or synthetic; what matters is its exact molecular structure. FDA-approved peptide drugs go through years of rigorous testing in…
