Tirzepatide Research Compound Guide: Dual GLP-1/GIP Agonism Explained

Tirzepatide: The Twincretin Research Compound

Tirzepatide (LY3298176) agonizes both GIPR and GLP-1R. It shows higher potency at the GIPR than the GLP-1R, inverting the assumption that GLP-1’s historical prominence reflects receptor primacy.

Tirzepatide Dual Receptor Contributions
GLP-1R Effects
Insulin secretion, glucagon suppression, gastric emptying delay, hypothalamic satiety — shared with semaglutide.
GIPR in Adipose Tissue
GIPR is highly expressed in fat tissue. Agonism appears to redirect fatty acid storage and improve adipose function — a key differentiator.
GIPR in CNS
Both GLP-1R and GIPR expressed in hypothalamic satiety centres — potentially creating additive appetite suppression.
Beta-Cell Synergy
GIPR augments GLP-1R-driven insulin release in a complementary, non-overlapping manner.
