Research Profile

  • Dual GIP/GLP-1 receptor agonist
  • 39-amino-acid synthetic peptide
  • Lyophilised for laboratory use
  • Third-party purity tested
  • Research use only

Tirzepatide is a synthetic 39-amino-acid peptide characterised in the literature as a dual agonist at the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Supplied as lyophilised powder for in-vitro research use only.

The above describes how this compound is characterised in the published peer-reviewed literature. It is not a claim about effects in humans.

Laboratory Handling

Tirzepatide is supplied as a lyophilised (freeze-dried) powder in a sealed glass vial. For laboratory reconstitution, add the desired volume of diluent (typically bacteriostatic water) slowly down the side wall of the vial. Swirl gently until fully dissolved - do not vortex or shake. Store reconstituted solutions at 2–8 °C and use within 4–6 weeks.

Use our Reconstitution Volume Calculator to compute the resulting mg/ml concentration.
