Dual incretin mechanism

Tirzepatide binds the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor. The combined signalling profile is the basis for the compound's distinct research interest versus single-agonist GLP-1 analogs.

  • GIP receptor agonism — insulinotropic and adipocyte signalling
  • GLP-1 receptor agonism — incretin and gastric motility pathways
  • Extended half-life via fatty-acid moiety and albumin binding

Published clinical literature

The SURPASS clinical program (including SURPASS-2, a head-to-head comparison against semaglutide) is the primary published body of evidence describing tirzepatide's dual-agonist pharmacology. All PX1 material is supplied strictly for laboratory research use.

Frequently asked questions

What is the difference between tirzepatide and retatrutide?

Tirzepatide is a dual GIP/GLP-1 agonist. Retatrutide adds a third target, the glucagon receptor, making it a triple agonist.

How is tirzepatide reconstituted?

Add bacteriostatic water to the lyophilized vial along the glass wall, swirl gently without shaking, and refrigerate at 2–8°C once dissolved.
