In this episode of the Peptides and Longevity Podcast, host Dr. Kenton Holtorf interviews Dr. Joseph Kleever, a board‑certified anti‑aging and regenerative medicine physician. The conversation explores the biology of senescent cells, their role in inflammaging, and why the immune system’s declining ability to clear them accelerates age‑related decline after age 60. Dr. Kleever explains the concept of "precision senolytics"—using natural flavonoids (quercetin, fisetin, long‑pepper), dietary strategies (intermittent fasting, fasting‑mimicking diets), and targeted peptides (GHK‑Cu, thymic peptides, mitochondrial peptides, BPC‑157, TB4) to prevent senescence, induce apoptosis of existing senescent cells, and restore stem‑cell function. He outlines practical protocols: periodic 3‑day water fasts or 5‑day fasting‑mimicking diets, followed by flavonoid supplementation to inhibit CD38, NAD⁺ repletion, and mitochondrial support. The dialogue also covers telomere biology, hormone balancing, neuro‑peptide approaches for chronic inflammatory response syndrome, and emerging technologies such as oral/ topical peptide delivery, powdered oxygen, and exosome‑based biologics. Throughout, Dr. Kleever emphasizes the clinician’s role as a gatekeeper of evidence‑based, cost‑effective therapies amid information overload, and highlights the synergy between lifestyle, supplements, and peptide‑based regenerative medicine for extending healthspan.
