Peptides and Longevity: Redefining Aging and Transforming Health with Dr. Kent Holtorf

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.
