Delivering Health

Peptides have become one of the most talked-about topics in longevity medicine. From GLP-1 medications to experimental compounds like BPC-157, SS-31, and MOTS-c, interest is growing rapidly. But what does the science actually tell us? In this episode of Delivering Health, Dr. John Neustadt welcomes back longtime friend and colleague Dr. Mark L. Gordon, a physician with extensive experience in neuroendocrinology, traumatic brain injury, and peptide research. Together, they explore how peptides function as signaling molecules throughout the body and why researchers are investigating their potential roles in inflammation, hormone regulation, mitochondrial function, and neurological health. One particularly fascinating area of discussion is the relationship between neuroinflammation, brain energy metabolism, and Alzheimer's disease. Dr. Gordon shares his perspective on how disruptions in hormone signaling and cellular energy production may contribute to neurological dysfunction, along with emerging peptide research investigating these pathways. In this episode, you'll discover: What peptides are and why they're gaining so much attention The potential relationship between peptides, neuroinflammation, and brain health The differences between oral and injectable peptides How peptide absorption and formulation can influence effectiveness The importance of distinguishing emerging research from established clinical treatments Why nutrition, exercise, sleep, and lifestyle remain essential foundations of health Dr. Neustadt and Dr. Gordon also discuss the growing confusion surrounding peptide products, including questions about effectiveness, administration, and regulation. While peptide science offers intriguing possibilities, many experimental compounds still lack rigorous human clinical evidence. Understanding that distinction is essential for making informed health decisions. Listen to explore the science, the unanswered questions, and the future of peptide research. About the guest Dr. Mark L. Gordon is a physician whose work focuses on neuroendocrinology, traumatic brain injury, hormone signaling, and investigational peptide applications.

Is knee replacement surgery inevitable when arthritis and cartilage damage progress? In this episode of Delivering Health, Dr. John Neustadt welcomes orthopedic surgeon Dr. Mark Petropoulos, author of Repair Not Replace, for a conversation about joint preservation, regenerative medicine, and alternatives to surgery. Dr. Petropoulos shares how witnessing his first knee replacement inspired him to investigate ways to help patients recover without surgery. He discusses platelet-rich plasma (PRP), prolotherapy, bone marrow-based procedures, and the importance of understanding the entire joint—not just cartilage. They explore how bone marrow lesions contribute to pain, why injection placement and ultrasound guidance matter, and how different knee injuries require different treatment strategies. From meniscus tears and ACL injuries to chronic osteoarthritis, this conversation examines when conservative care may be appropriate and when surgery remains the better option. Topics include: The evolution of regenerative orthopedics PRP and its proposed mechanisms Nonsurgical knee arthritis management The role of rehabilitation and nutrition How to evaluate treatment claims and choose an experienced clinician Guest: Dr. Mark Petropoulos Website: https://victoryinmotion.com Book: Repair Not Replace Regenerative procedures are not appropriate for every patient, and some remain experimental. Treatment decisions should be based on an individualized assessment of risks, benefits, and available evidence.

Can a mini trampoline really improve your health? Rebounding has gained attention for its potential benefits for balance, cardiovascular fitness, bone health, and lymphatic circulation. But how much of the science actually supports these claims? In this episode of Delivering Health, Dr. John Neustadt sits down with Steve Carver, a fitness professional with more than 30 years of experience and a longtime expert in the rebounding industry, to explore the science behind mini trampolines. From proprioception and muscle activation to fall prevention and low-impact cardiovascular exercise, they discuss why rebounders may offer more versatility than most people realize. They also examine some of the most popular claims surrounding rebounding, including its potential effects on bone density and lymphatic movement, the frequently cited NASA trampoline research, and where scientific evidence remains limited. In this episode, you'll discover: What rebounding is and how it differs from traditional trampoline exercise How unstable surfaces challenge balance, coordination, and core stability Why popular claims comparing rebounding with running can be misleading How to incorporate rebounding into a well-rounded exercise routine Why consistency and enjoyment are essential for long-term health Steve also shares practical advice for choosing a rebounder and explains why consumers should be skeptical of products promising to cure diseases or deliver extraordinary health benefits. Whether you're interested in healthy aging, improving balance, or finding an enjoyable way to stay active, this conversation offers a grounded look at what rebounding may—and may not—do for your health.

Are you tired of being told your labs are "completely normal" even though you feel exhausted, foggy, and run down? In this episode of Delivering Health, Dr. John Neustadt sits down with Dr. Tracy Gapin — a board-certified urologist of over 20 years who hit his own burnout wall at age 40 and transformed his health through functional medicine. Together, they pull back the curtain on conventional medicine's blind spots and explain why standard healthcare is built to manage disease rather than optimize health. Dr. Gapin shares his "Test, Design, Track" framework for precision performance medicine, detailing the hidden constraints — from heavy metals to mold — that can override even the best diet. You'll learn the five blood-testing categories that conventional doctors routinely miss, including why ApoB is a far more accurate cardiovascular predictor than standard cholesterol, and why fasting insulin is an early-warning system for metabolic dysfunction. Whether you're a high-achieving executive feeling the slow drain of chronic pressure, or simply looking to regain mental clarity and physical edge, this conversation offers a practical, science-backed roadmap for taking control of your health. - - - - - About the Guest: Dr. Tracy Gapin is a board-certified urologist with over 20 years of experience in robotic surgery and men's health. After experiencing severe burnout, chronic exhaustion, and weight gain around age 40 — and being told by his own doctor that his standard labs were "perfectly fine" — he shifted his career toward functional medicine, epigenetics, and hormone optimization. Today he is the founder of the Gapin Institute and Peak Launch, where he practices "precision performance medicine" to help executives, entrepreneurs, and high-achievers optimize their physical and cognitive performance. He also trains other physicians to transition into this model through the Peak Launch Institute. - - - - - Social Handles: Instagram: https://www.instagram.com/drtracygapin/?hl=en Website: https://peaklaunch.com Free High Performance Health Handbook: https://peaklaunch.com/guide Peak Launch Institute: https://peaklaunchinstitute.com - - - - - Follow NBI & Dr. John Neustadt, ND: Website: https://nbihealth.com/ Delivering Health Podcast: https://nbihealth.com/podcast-archive Shop NBI Supplements: https://shop.nbihealth.com/ Facebook: https://www.facebook.com/nbihealth/ Instagram: https://www.instagram.com/nbi_health/ X (Twitter): https://x.com/JohnNeustadt LinkedIn: https://www.linkedin.com/in/john-neustadt-nd-1553576/ YouTube: https://youtube.com/user/NBIHealth Shop supplements: https://shop.nbihealth.com/ - - - - - PODCAST Thank you for listening.
