GLP-1 Peptides: Full List (Semaglutide, Tirzepatide, Retatrutide and More)

Peptides are the hottest topic in metabolism right now. Here is an educational guide with the names of the most searched ones —so you understand what each is— and how your own body makes similar peptides.

What a GLP-1 peptide is

A peptide is a short chain of amino acids. GLP-1 is a natural incretin your gut releases when you eat. Many modern drugs are peptides that mimic GLP-1.

  • Semaglutide — brands Ozempic, Wegovy, Rybelsus.
  • Tirzepatide — brands Mounjaro, Zepbound (dual GLP-1/GIP).
  • Retatrutide — investigational (triple GLP-1/GIP/glucagon).
  • Liraglutide — brands Saxenda, Victoza.
  • Dulaglutide — brand Trulicity.
  • Exenatide — one of the first analogs.
  • Survodutide and pemvidutide — in clinical trials.
  • BPC-157 and AOD-9604 — peptides mentioned in other contexts.

The peptides your own body makes

Before any drug, your gut produces GLP-1, GIP and glucagon in response to food —especially protein—. Understanding this is key: physiology comes first.

Why understanding them matters

Knowing the peptides helps you understand your metabolism, pancreas and liver as one system — the educational approach of the Salinas Method.
