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.

What if your concussion wasn’t just about the hit to your head, but everything that was already simmering in your body? In this episode of Peptides and Longevity, neurosurgeon and functional medicine practitioner Dr. Chad Prusmack joins us to unpack precision medicine, environmental subconcussion, and why toxins, infections, autonomic imbalance, and data-driven rehab can make or break brain recovery.
----
Dr. Chad Prusmack is a board-certified neurosurgeon and one of the only neurosurgeons in the United States to also hold a functional medicine certification. After years of operating in traditional neurosurgery, he saw too many patients whose scans looked ‘perfect’ but who were still suffering, which pushed him to integrate multi-omics, precision testing, and systems-level thinking into his practice.
He is the founder of Resilience Code, a 45,000-square-foot health and performance center in Denver that blends neurosurgery, functional medicine, strength and conditioning, neurofeedback, and comprehensive rehab under one roof. As a primary neurosurgical consultant for the Denver Broncos and the United States Olympic Committee, he specializes in neurodegenerative disease, concussion, post-concussion syndrome, and performance medicine. His mission is to shine a high-definition light on the continuum between ‘healthy’ and ‘diseased,’ so patients can finally understand why they feel the way they do and what to do next.

In this episode of Peptides & Longevity, Dr. Kent Holtorf speaks with Dr. Sanjeev Goel, a Toronto-based biohacker and longevity expert. They explore how psychedelics, peptides, and data-driven therapies are transforming health, performance, and aging—revealing what’s next in the science of self-optimization.
Born in Montreal and now based in Toronto, Dr. Goel’s journey has been far from conventional. With over five decades of lived experience and a résumé that spans remote medical service in Himalayan villages to teaching mindfulness to healthcare professionals, his voice carries both wisdom and credibility. His biological age is a full ten years younger than his chronological one, a living testament to the anti-aging practices he preaches. But his path hasn’t been without hardship. In 2019, a severe Lyme-like illness brought him face-to-face with his own mortality. The experience sparked a deeper commitment to healing, self-exploration, and science-backed rejuvenation.

Reignite your libido from the inside out—no shame, no guesswork. In this episode of Peptides and Longevity, Dr. Valerie Phillips joins us to uncover what really drives desire. She shares how rebalancing your hormones, optimizing sleep, calming stress, and even healing your gut and pelvic floor can reignite libido, naming certain peptides may be the missing piece to bringing your passion back.
Loss of desire isn’t a life sentence—it’s your body’s way of asking for balance. In this episode of Peptides and Longevity, Dr. Valerie Phillips reveals how she helps women reignite passion by looking beyond hormones to the deeper story unfolding inside the body. She explores what happens when communication between mind, metabolism, and mood breaks down—and how restoring that dialogue can transform not only energy and confidence, but connection itself.
Tune in to hear what most people overlook when libido fades: subtle shifts in stress chemistry, sleep cycles, gut health, and emotional health that quietly drain vitality. Dr. Phillips shares how small, strategic adjustments can unlock a natural return of desire, showing that when your body feels safe, nourished, and rested, passion often follows. The takeaway: it’s not about chasing youth—it’s about rediscovering the spark that balance brings naturally.
Valerie Phillips, ND (Dr. Val) is a native Angelino who started studying the medical arts as a teenager in Magnet School. She studied Biochemistry at U.C. Davis, and subsequently pursued research in Neuro-Pathology at U.C. San Francisco. She also volunteered at the Berkeley Free Clinic and at the Native American Health Center in San Francisco, and became a “lay healthcare worker,” delivering limited primary care services to the underserved populations of the San Francisco Bay area. Based on this experience, Dr. Val decided to pursue her long term interest in eastern and alternative forms of Medicine by pursuing a Naturopathic Medical degree at Bastyr University in Kenmore, WA. The education was the perfect blend of western scientific medical thought combined with herbal traditions from across the globe, nutrition, physical medicine and many more disciplines designed to train physicians to see all the aspects of the human body as a holistic unit.

The secret to living better for longer starts with removing the cells that make you old. In this episode of Peptides and Longevity, Dr. Joe Cleaver pulls back the curtain on senolytics, showing how to clear senescent cells and build you back up with mitochondria, hormones, and targeted peptides.
Want to age in reverse? Start by clearing out the cells making you old. In this episode of Peptides and Longevity, Dr. Joe Cleaver reframes longevity around one simple idea, which is that you remove what ages you and then rebuild what keeps you young. He explains how senescent cells accumulate, why they become inflammatory factories, and how fasting and senolytics can clear the backlog. He then shows how to protect and upgrade mitochondria, why telomeres work as a useful marker rather than a destiny, and where peptides belong. The result is a stepwise, precision plan that starts with clearance, moves into cellular energy, and finishes with targeted repair for brain, skin, hair, and whole-body performance. Watch the full episode now and learn how to start clearing the cells that make you old.
Dr. Joseph Cleaver is a board-certified internist and fellow in anti-aging and metabolic medicine who blends preventive lifestyle medicine, regenerative therapeutics, and peptide science. He teaches clinicians nationwide and sees patients through the Paradigm Wellness Medical Group. He also hosts small-group masterminds on longevity and regenerative medicine at his winery in Sonoma.
