  <title>E 205 PEPTIDE PLAYBOOK – PART 5 Understanding How Aging Happens Studying Mitochondrial Dysfunction in Aging</title>
  <description>Welcome back to The Peptide Playbook! In this episode, I’m joined by my colleague Dr. Robert Frankel, and we dive deep into one of the most exciting topics in anti-aging and wellness right now: mitochondrial health. We break down what mitochondria actually do (in a way that finally makes sense), why they’re so critical for energy, aging, and disease—and how peptides like NAD, MOTS-c, and SS-31 may help optimize how your body functions at a cellular level. One of the most fascinating parts? The concept of “exercise in a bottle”—how certain peptides can mimic some of the metabolic benefits of working out by improving energy production, fat metabolism, and even muscle function. We also talk about:  Why energy deficiency is at the root of many health issues&amp;amp;nbsp; What “zombie cells” are and how they accelerate aging&amp;amp;nbsp; The real role of free radicals (and why antioxidants alone aren’t enough)&amp;amp;nbsp; How to think about peptides safely and strategically&amp;amp;nbsp;  This is a powerful, science-backed conversation—but still approachable and practical. As always, this is for educational purposes only—make sure to consult with a qualified professional before starting any treatment. 00:00:00 Intro – Welcome to The Peptide Playbook 00:01:10 Why This Topic Matters (Mitochondria &amp;amp;amp; Aging) 00:03:30 What Are Mitochondria?
