Renee Belz & Lauren Sambataro The GLP-1 Dosing Problem with Jay Campbell l Smarter Dosing & Behavior Changes for Fat Loss, Brain Health & Metabolism
What if everything you thought you knew about peptides—and even GLP-1s—was only scratching the surface? In this episode, we sit down with Jay Campbell to unpack the rapidly evolving (and often misunderstood) world of peptide therapy, from regulation challenges and dosing risks to the truth about purity and sourcing. Jay shares what’s really happening behind the scenes with major pharmaceutical players, what’s coming next with compounds like Retatrutide, and why so many people are getting GLP protocols wrong. The conversation goes beyond hype, diving into how to work with your biology through smarter protein strategies, muscle-building, and personalized optimization. If you’re curious about the future of longevity medicine, this episode will completely shift your perspective.
