Peptide delivery: nasal, patch, injectable differences

Full Show Notes: bengreenfieldlife.com/cook2026

 In this episode, I welcome regenerative medicine expert Dr Matthew Cook to explore what's new and exciting in regenerative medicine. You'll hear firsthand about groundbreaking stem cell treatments, the best peptide stacks, and how exosomes are shaping the future of health and longevity. Whether you're curious about the science behind anti-aging, optimizing recovery, or what's next for wearable tech and AI in healthcare, this conversation delivers practical insights and actionable takeaways.

Dr. Cook graduated from the University of Washington School of Medicine, completed his residency in anesthesiology at the University of California San Francisco (UCSF), and completed fellowships in Anti-Aging, Metabolic and Functional Medicine, and Peptide Therapy with the American Academy of Anti-Aging Medicine.

After a decade focused on functional medicine (with 14 years prior working as an anesthesiologist), Dr. Cook's specialty is addressing the most challenging conditions. His proprietary multimodal approach regenerates, repairs, and restores health on a cellular level, dealing with root causes rather than masking symptoms.
