Healthspan, Epigenetics & Peptides: Human Flourishing with Dr. Melissa Grill-Petersen

Dr. Melissa Grill-Petersen, DC, MS, BCHH, is the founder and CEO of Human Longevity Global and co-founder of Peptide University, and in this episode she breaks down peptides in plain terms: naturally occurring signaling molecules that instruct the body's existing pathways rather than replace them. She and Freddie dig into why peptide quality of effect depends on foundational health — cell membrane integrity, nutrient status, hormone balance — and why she sees peptides as one input among many, not a shortcut around the basics. The conversation also covers the "exposome," the case for designing environments (cities, workplaces, healthcare systems) around healthspan rather than sick-care, and the emerging economic argument for longevity research reframed around health-adjusted life years.

Beyond the science, Dr. Melissa shares the personal story that shaped her mission — watching her mother's cancer go into remission through an intensive lifestyle shift, then return after returning to old patterns — and how that experience shaped her belief that inputs, not just genetics, drive health outcomes. The episode closes with a quick-fire round on her favorite peptide for cell membrane support and where peptide delivery research is headed next. A candid, systems-level look at longevity, personal responsibility, and human flourishing from one of the field's most recognized educators.
