In this episode of the NRG Biolabs Peptide Research Podcast, Nora Grant and Evan Cross break down one of the most common questions in modern peptide science. They explain what peptides are, how they function as short amino acid chains, and why researchers study them as highly targeted signaling molecules. Listeners learn how peptides differ from proteins, why they are central to cellular communication, and what makes them so valuable in models involving recovery, inflammation, metabolic activity, and mitochondrial health. Nora and Evan also clarify the difference between research grade peptides and FDA approved peptide drugs, clearing up many of the misconceptions circulating online. This episode gives listeners a simple but comprehensive foundation for understanding peptide research and why interest in this field continues to grow.
