GIP receptor
What a GLP-1 receptor agonist actually does: which receptors it reaches, how it slows gastric emptying, and the satiety pathway it runs through.
What is GIP receptor?
The glucose-dependent insulinotropic polypeptide receptor.
Tirzepatide agonizes it alongside GLP-1, which is the proposed reason its gastric-emptying delay runs deeper than semaglutide's — and, downstream, why its side-effect profile is not simply a stronger version of the same thing.
GLP Watchdog writes these definitions from FDA labels and peer-reviewed PubMed literature.
