Jay Campbell of BioLongevity Labs joins me to make a claim that'll stop a lot of people in their tracks: peptides are the single greatest medical intervention of all time, and he puts them ahead of penicillin. We get into why he believes that, what peptides actually do in the body, and why they're changing the conversation around fat loss, muscle, and aging faster than most doctors can keep up with.

We spend a good chunk of the episode on the GLP-1 class of drugs, including semaglutide, tirzepatide, and retatrutide. People are getting dramatic results on these, and Jay doesn't dispute that. His concern is how they're being prescribed and taken. They're overprescribed, often handed out without a plan, and a lot of people are losing weight in ways that don't make them healthier. We talk through the basics that need to be in place before you take any peptide, GLP-1s included, so the drug supports your results instead of becoming the whole strategy.

From there we look at what's come out in the last four years and what's coming next: newer peptides that can help build muscle, improve metabolic health, and move your biomarkers in the right direction. Jay also explains why he believes the first people who'll live to 150 are already alive today, and what separates the people who'll get there from the people who won't. If you've been curious about peptides but don't know where to start, start here.
