E 205 PEPTIDE PLAYBOOK – PART 5 Understanding How Aging Happens Studying Mitochondrial Dysfunction in Aging

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
• What "zombie cells" are and how they accelerate aging
• The real role of free radicals (and why antioxidants alone aren't enough)
• How to think about peptides safely and strategically

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.
