Understanding Incretin Science: GIP, GLP-1 and Glucagon

6 min read · Updated July 2026

Most peptide headlines come back to three receptors: GIP, GLP-1, and glucagon. Understanding what each one is studied for makes the rest of the research far easier to follow.

Frequently asked questions

What is the incretin system?
The incretin system is a set of hormone pathways involved in metabolic signaling after eating. It is a major focus of peptide research.
What is the difference between a dual and triple agonist?
A dual agonist engages two incretin receptors (such as GIP and GLP-1); a triple agonist adds a third, the glucagon receptor.
