  1. Number 1: Breakthroughs in Longevity Science and Aesthetics from the Inside Out with Oral Peptide Bioregulators

    I did not plan to give this talk. I arrived at the AIMS Symposium, realized how much of the room was aesthetics, and did not have a single slide on the oral skin bioregulators we have been working on for years. So I rebuilt it. What is happening in that room is worth paying attention to, because beauty and functional medicine are being pushed together and nobody has decided yet whether the plastic surgeons, the regenerative doctors, the orthomolecular people or the naturopaths end up owning it. The premise underneath all of it is simple enough. People who feel good on the inside want to look like it on the outside, and the inside is where the instruction actually gets written. So I skipped my usual hour of theory and went to the data. What a peptide is, what a bioregulator is, and why the distinction matters: peptides bind at the cell surface and signal, while bioregulators are two to four amino acids, small enough to enter the nucleus and sit down on the DNA, turning genes of aging down and youthful ones up, one tissue at a time. Then the skin studies. Sirtuin 1 and 6 and collagen synthesis in young and aged cultures, markers of proliferation and repair going one way, caspase-3 and MMP-9 going the other, and a human trial on a placenta derived dermatologic peptide measuring wrinkle depth, elasticity, hydration and pigment across twelve weeks. After that, the parts of the catalogue people ask me about most: the thyroid bioregulators and the separate thyroid axis version that is the one that touches antibodies, the brain and vascular bioregulators, the pancreas work in type 2 diabetes, muscle and grip strength, and the long-running biologic age trials out of Russia that rotate five to seven bioregulators and track telomere length and methylation age. I also tell the story of where all of this came from, which starts with the Soviet military noticing that its cosmonauts, jet pilots and submariners were aging far faster than they should have been. Take the mechanism seriously and the aesthetic result stops being the goal and starts being the receipt. - - - - - About the Host: Dr. Kent Holtorf, MD has spent most of his career on the patients other clinics send away: tick-borne illness, chronic fatigue syndrome, fibromyalgia, CIRS, mast cell activation, long COVID, and the multi-system cases that never fit one specialty. He is the medical director of Holtorf Medical Group, the founder and medical director of Integrative Peptides, and president and medical director of the National Academy of Hypothyroidism, a nonprofit built around the argument that thyroid diagnosis in the United States has not caught up with its own published literature. He came to peptides as a patient first. Years of chronic Lyme, Babesia, and Bartonella that did not respond to high-dose IV antibiotics ended in heart failure from fibrosis, and it was a course of peptides picked up abroad that turned it around. He has since given close to a hundred CME-approved presentations worldwide, published in peer-reviewed journals, sat on editorial boards in endocrinology and specialty medicine, and written Mold Illness: The Peptide Protocol for the Rapid Treatment of CIRS. This talk is the first time he has taken the bioregulator work into aesthetics. - - - - - Social Handles: Website: https://holtorfmed.comhttps://integrativepeptides.comInstagram: https://www.instagram.com/integrativepephttps://www.instagram.com/holtorfmedicalgroup - - - - - PODCAST Thank you for listening.

  3. Number 3: Unlock the Secrets to Longevity and Chronic Illness With 3rd Generation Oral Peptides

    I keep coming back to one idea in this talk: the immune system is not a side character in aging and chronic illness—it is closer to the director. I lay out the teeter-totter first: the TH1 and regulatory side against the TH2 and TH17 side, and how the thymus winding down from childhood on quietly shifts that balance until an aged immune phenotype takes over. From there, the dominoes are familiar to anyone who works with complex patients: hypothalamic and pituitary hormone dysfunction, mitochondria slipping into the cell danger response, leaky gut, cognitive fog, and the low-grade inflammation that tracks with how old you actually are on the inside. Then I spend real time on senescent cells, because that is where a lot of the longevity research has landed. These are worn-out cells that should be cleared and instead stick around, secreting the inflammatory signals that show up in the diseases we associate with aging, while falling natural killer function lets them pile up. I connect that to the chronically ill patient, who is often carrying a heavy senescent load from an unresolved infection or autoimmune process, and I make the case for immune-directed peptides and bioregulators, the third-generation oral tools I have been working with, as a way to work on that layer. It runs dense, and that is on purpose. The more you know here, the more you know you do not know. - - - - - About the Host: Dr. Kent Holtorf, MD, has spent most of his career on the patients other clinics send away: tick-borne illness, chronic fatigue syndrome, fibromyalgia, CIRS, mast cell activation, long COVID, and the multi-system cases that never fit one specialty.

  4. Number 4: Goldilocks Dosing: The Sweet Spot for Calm, Smarter Focus

    Most people reach for another coffee when their brain is tired—but what if the real issue is how your brain makes and spends energy? In this episode of Peptides and Longevity, Dr. Gregory Kelly joins us to break down what nootropics are, how caffeine impacts focus and mood, and why mitochondrial health and chronobiology matter for sustainable brain performance. Dr. Gregory Kelly is a naturopathic physician and the director of product development at Neurohacker Collective, where he guides the development of nootropic, mitochondrial, immune, and healthy-aging formulas. He is the author of ‘Shape Shift,’ was editor of the Journal of Alternative Medicine Review, and a contributor to the Textbook of Natural Medicine, with more than 30 publications indexed in PubMed. Before entering naturopathic medicine, he served as a Navy officer and earned an engineering degree, later redirecting his curiosity toward how people and traditional cultures care for their health. He has taught advanced clinical nutrition, counseling skills, and doctor–patient relationships at the University of Bridgeport and the College of Naturopathic Medicine. With over two decades immersed in supplements, natural medicine, and chronobiology, his work centers on nootropics, anti-aging, regenerative medicine, weight management, sleep, and the timing of biological processes that shape performance and health.

  5. Number 5: When The Thyroid Labs Look Fine And The Patient Is Not

    Most of the patients I see have already been told their thyroid is fine. A TSH in range, a free T4 in range, and a conversation that stops there. My argument in this session is that in chronic illness those two numbers are the least informative part of the panel, because they tell you about signalling and circulating supply rather than about what is getting into the cell and being used. So I go through what I look at instead. Free T3 rather than free T4 alone. The relationship between free T3 and reverse T3, because a rising reverse T3 changes the picture even when everything else reads as acceptable. And clinical signs that are not on the panel at all: basal metabolic rate, body temperature, and the relaxation phase of a reflex, which is old fashioned and, to my eye, still underused. None of this is a replacement for the standard tests. It is what I think has to sit alongside them before you tell a sick patient there is nothing wrong. The second half is about why I pair that with immune modulation. In the chronically ill patient you tend to see the immune system shifted in one direction and stuck, and my view is that treating the thyroid without addressing that shift leaves you fighting the same problem twice. This is where peptides come in, and the mechanical distinction is the part worth holding onto. A hormone goes into the nucleus and changes protein synthesis, which makes it slow to come on and slow to come off. Peptides mostly act at the cell surface and work through a cascade of secondary messengers, so they come on and off faster and tend to have several effects at once rather than a single one. That is why I describe hormones as the blunt instrument and peptides as the finer one, and it is also why I am careful about stacking them without knowing what each is doing. I walk through the classes I use and what they are being studied for: thymic peptides for immune balance, pineal peptides and bioregulators in the longevity and sleep space, nootropic peptides for cognitive and brain injury work, mitochondrial peptides, and the melanocortin family. I go through a lot of published work quickly, and I want to be plain about what that evidence is. A large part of it is animal work, small trials, and research from outside the United States. Several of the compounds I name are not approved by the FDA for the uses discussed, and some are not available as prescribed medicines at all. I share the mechanisms because I think clinicians should know them, not because the case is closed. This session was recorded for a clinical audience and it includes my own interpretation of the literature and my own clinical approach, neither of which is a standard of care. It is not medical advice, no dosing guidance from it should be applied to yourself, and nothing here is a reason to change or stop a prescribed medication. If any of it is relevant to you, take it to the clinician who is actually looking after you. - - - - - About the Host: Dr. Kent Holtorf, MD, is the medical director of Holtorf Medical Group and the founder of Integrative Peptides. He is also a founder and director of the non profit National Academy of Hypothyroidism, which exists to get evidence based information on the diagnosis and treatment of hypothyroidism to doctors and patients. His clinical focus is the patient nobody has been able to help: tick borne illness, chronic fatigue syndrome, fibromyalgia, CIRS, MCAS, long COVID, traumatic brain injury and neurodegenerative disease, alongside hormone optimization and longevity medicine. He works at the mechanism level, and he is candid that much of what he discusses sits ahead of where mainstream guidelines currently are. - - - - - Social Handles: Holtorf Medical Group: holtorfmed.com National Academy of Hypothyroidism: nahypothyroidism.org - - - - - PODCAST Thank you for listening.
