Episode 259: What Is a Peptide, Really? GLP-1s, Retatrutide, & the Truth Behind the Hype
If someone tells you, "It's just a peptide," that should be the beginning of the conversation, not the end.
Peptides are chains of amino acids, but the word tells you very little about what you're actually taking. It doesn't tell you whether something is a supplement, medication, investigational drug, FDA approved, or even whether the product contains what the label says it does.
In this episode, I break down what "peptide" really means and why the term has become so confusing in the world of weight loss. I explain the differences between FDA-approved medications, compounded medications, investigational drugs, and research peptides sold online.
I also discuss retatrutide, an investigational medication that targets three hormone receptors, and why calling something a peptide does not automatically make it natural or safe.
Most importantly, I'll walk you through the questions you should ask before taking any peptide or weight loss medication, including what it is, where it came from, whether it has been studied, and whether you have appropriate medical supervision.
Episode Highlights:
● Why "peptide" describes a type of molecule, not a safety rating
● What retatrutide is and how it differs from semaglutide and tirzepatide
● The differences between FDA-approved, compounded, investigational, and research products
● Why dramatic results and social media testimonials don't prove safety
● The questions you should ask before taking peptide or weight loss therapies
● Why "natural" does not automatically mean safe or effective
