In this episode of Bulletproof Radio, we take a deep dive into the exciting topic of peptides—what they are, what they do and ideal dosages. We’ll also introduce you to a brand-new mitochondrial peptide that’s being looked at as a global antiaging molecule.My guest is a board-certified anesthesiologist and fellow-trained interventional pain medicine physician who graduated in the first-ever class of physicians trained and certified in peptide medicine. Dr. Heather Smith-Fernandez founded the Regenerative Institute of Medicine in Naples, Florida. She also founded Peptology™, the study and clinical application of peptides in living beings, both human and non-human. She uses peptides in all areas of her practice, such as regenerative treatments, advanced aesthetics, sexual health, hormone therapy, preventive medicine, and advanced lab testing. She also trains other physicians in specific Peptology™ protocols at her institute.Peptides are the real deal. After using them for a period of time, “There's a noticeable difference in how you feel, how you think, how you sleep,” Dr. Heather says.And while she works with a broad range of peptides, she has her favorites. “I think that my love with epitalon is... I love that peptide. I think it's the most understated peptide in our toolbox and I use it a lot. It has tremendous capability and it works in so many different areas. It's one of the true antiaging peptides, in my opinion, and it promotes better sleep, healthier sleep, much healthier sleep, and when it's used in combination with certain other peptides, you get a synergistic effect. Literally, people can feel their brain getting younger when they're using epitalon regularly.”You’ll find out in this episode why peptides are such a powerful treatment for many health conditions. Their use can improve both your healthspan and lifespan. Enjoy the show! ...
