GLP-1 medications are the most talked-about compounds in modern medicine — and the most misunderstood. Most of the conversation focuses on weight loss results. Almost none of it explains the biology driving those results.
In this episode of Peptides Explained, we break down the science behind three of the most prescribed GLP-1 compounds: semaglutide, tirzepatide, and retatrutide.
Topics covered include:
- What GLP-1 is and why it matters for metabolic regulation
- How semaglutide mimics a naturally occurring gut hormone to suppress appetite and regulate blood sugar
- What makes tirzepatide different — and why its dual-receptor action changes the clinical picture
- Where retatrutide fits as a triple-agonist and what the early data suggests
- How these medications interact with insulin secretion, gastric emptying, and satiety signaling
- Side effects, clinical context, and what the research actually supports
Whether you're a clinician, a patient, or just someone trying to understand what these medications are actually doing in the body — this episode gives you the mechanistic foundation the headlines leave out.
