In this episode of What Happens in Vagus, host Dr. Stephanie Canestraro sits down with Cheyanne Welton, widely known as The Biohacking Nurse, to explore the cutting-edge world of peptides, microdosing GLP-1s, and strategies for stabilizing mast cell activation syndrome (MCAS). Cheyanne shares her personal health journey — from battling Lyme disease, mold toxicity, and autoimmune conditions to discovering how specific peptides transformed her recovery and resilience.

Together, Dr. Stephanie and Cheyanne unpack the science and practical applications of BPC-157, CJC/Ipamorelin, Tirzepatide, TB-500, GHK-Cu, and more. They discuss how microdosing GLP-1 agonists can reduce inflammation, support hormone balance, improve metabolic health, and even calm microglial activation in the brain. Cheyanne also reveals incredible real-world stories, including how peptides helped her mother avoid hospitalizations, and why starting with the right peptide — and the right dose — is key to success.

The conversation goes beyond theory, diving into post-COVID health challenges, POTS, histamine intolerance, spike protein protocols, and strategies for working with functional medicine practitioners to get results. Whether you’re an athlete, someone navigating chronic illness, or simply curious about biohacking for longevity, this episode offers actionable insights and inspiring success stories from the frontlines of functional medicine and regenerative health.

Cheyanne's Bio: Cheyanne is a registered nurse and functional wellness expert who became The Biohacking Nurse after facing years of complex, unresolved health challenges that left even doctors stumped. Determined to heal, she dove deep into functional medicine, biohacking, and root-cause approaches—becoming her own best case study. Today, she helps others navigate their own healing journeys using the tools, strategies, and cutting-edge therapies that changed her life—from peptides and detox to lifestyle upgrades and beyond. She calls Idaho home and loves the mountains and cold plunging in the lakes. When she is not studying health, you can find her gardening barefoot and enjoying all things homemaking.
