Peptides: Hype vs Science with Leigh Baxt, PhD

Peptides are everywhere right now. From social media influencers and wellness clinics to fitness circles and longevity enthusiasts, they're being marketed as the next big thing for recovery, muscle growth, anti-aging, and optimization. But what does the science actually say?In this episode, we sit down with Leigh Baxt, PhD, with nearly two decades of experience in translational science and drug development, to unpack the growing peptide trend. We discuss how drugs are actually developed, why most therapeutic ideas fail, the difference between FDA-approved peptide medications and unregulated compounds, and how marketing often outpaces evidence.
