Tirzepatide: The Complete Research Guide to the Dual GLP-1 GIP Receptor Agonist

What Is Tirzepatide?

Tirzepatide is a synthetic peptide with a molecular weight of 4813.45 and molecular formula C225H348N48O68. It functions as a dual receptor agonist, simultaneously activating both the GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptors. This coordinated dual mechanism makes Tirzepatide a uniquely valuable tool for metabolic research.

Mechanism of Action

Tirzepatide binds to and activates GLP-1 and GIP receptors with balanced affinity. GLP-1 receptor activation enhances glucose-dependent insulin secretion, slows gastric emptying, and promotes satiety. GIP receptor activation complements these effects by enhancing insulin response to nutrient intake and improving lipid metabolism. The combined dual agonism produces coordinated metabolic effects that are greater than either receptor activation alone.

Key Specifications at G25

G25 Tirzepatide is supplied as a white to off-white lyophilized powder with purity exceeding 99 percent verified by independent HPLC and mass spectrometry. Available sizes range from 5mg to 60mg per vial in eight graduated options: 5mg, 10mg, 15mg, 20mg, 30mg, 40mg, 50mg, and 60mg. Recommended storage at 2 to 8 degrees Celsius protected from light.

Research Applications

Tirzepatide supports a broad range of metabolic investigations including glucose homeostasis and insulin sensitivity, appetite regulation and energy balance, body weight regulation and obesity mechanisms, cardiometabolic outcomes, and incretin receptor pharmacology. The availability of eight vial sizes enables dose-response studies from exploratory through confirmatory experimental designs.

Quality Documentation

Every batch of G25 Tirzepatide is accompanied by full Certificates of Analysis including HPLC chromatograms and mass spectrometry spectra. Third-party laboratory verification provides independent validation of purity and identity.
