What if the goal isn't just living longer, but feeling vital the whole way through? Peptides have jumped from the fringe to the mainstream, and most of what you'll find online comes from dubiously credentialed sources. In this episode, Jeff sits down with Dr. Aleksandra Gajer, an emergency medicine physician who spent a decade in the ER before founding The Gajer Practice and moving into longevity and regenerative medicine. They unpack what peptides really are and how to think clearly about a fast-moving, lightly regulated space. The conversation covers: What peptides actually are, and why insulin and GLP-1s belong to the same family BPC-157 and TB-500 for healing tendons, ligaments, and stubborn injuries Growth hormone-promoting peptides like sermorelin and tesamorelin for muscle and body composition The gray market, compounding pharmacies, and the FDA's shifting rules Cancer risks, contraindications, and who should be cautious This episode is for anyone curious about peptide therapy, longevity, and healing who wants grounded information instead of internet hype.
