Peptides for People: The Difference Between Evidence and Hype

This week on Dr. Simpson: The Unfiltered MD, we explore the tale of two peptides. On one side are GLP-1 medications like Zepbound and Ozempic, which continue to show benefits far beyond weight loss, including promising findings in cancer risk, kidney disease, psoriasis, and arthritis. On the other side are the unproven peptides sold online and promoted by wellness influencers, gym bros, and even some physicians despite little evidence of safety or effectiveness. We also discuss why clinical trials matter, what Vioxx taught medicine about drug safety, declining alcohol consumption, measles, RSV vaccines, wildfire smoke, and why the same evidentiary standard should apply to every health claim.
