What Are Peptides? The Building Blocks Behind Modern Therapeutic Compounds

What Are Peptides? The Building Blocks Behind Modern Therapeutic Compounds

Peptides are everywhere in the health and longevity conversation right now — but most of what's out there skips the fundamentals. Before you can understand semaglutide, BPC-157, or any other compound making headlines, you need to understand what a peptide actually is at the biological level.

In this episode of Peptides Explained, we lay the foundation:

  • What peptides are and how they differ from proteins and small molecules
  • How peptides function as signaling molecules in the body
  • Why the body's own peptide systems are the basis for modern therapeutic compounds
  • The difference between endogenous peptides and synthetic or compounded versions
  • Why understanding mechanism matters before evaluating any peptide claim

This is the episode to send someone who's heard about peptides but doesn't know where to start. No hype, no bro science — just the biology you need to make sense of everything that comes after.
