Are Peptides the New Snake Oil? What the Actual Science Says With Barbell Medicine

About this episode

The episode discusses the lack of scientific evidence supporting the use of peptides and the importance of rigorous research before using such substances.

Dr. Spencer Nadolsky and Karl bring on Dr. Austin Baraki and Dr. Jordan Feigenbaum from Barbell Medicine to cut through the peptide hype and explain why most of the research peptides people are currently injecting have no randomized controlled trial data in humans, were abandoned by pharmaceutical companies because they failed or showed harm signals, and may not even contain what is on the label. The core message is simple: calling something a short chain amino acids does not make it safe, natural does not mean studied, and having a standard of evidence before putting something in your body is not being close minded it is basic medicine.
