Most incretin-class peptides studied to date act on a single receptor. Tirzepatide is structurally notable because one molecule carries agonist activity at two.
The incretin system is a set of gut-derived hormone signals that participate in glucose regulation and energy metabolism. Research peptides in this class are designed to bind and activate specific receptors in that system. A mono-agonist targets one receptor. Tirzepatide is designed as a dual agonist — one peptide chain with activity at two distinct receptor targets, with reported higher affinity for the GIP receptor than for the GLP-1 receptor.
That matters to researchers for a practical reason: comparing a dual agonist against mono-agonist compounds isolates what the second receptor contributes, which is difficult to study by combining separate molecules with different pharmacokinetics.
Receptor targets
GLP-1 receptor
Glucagon-like peptide-1 receptor. The most extensively characterised incretin target, and the basis of the single-agonist peptide class that preceded this one.
GIP receptor
Glucose-dependent insulinotropic polypeptide receptor. The second incretin axis, and the axis that — combined with GLP-1 activity in a single chain — defines tirzepatide as a dual agonist.

Common questions
What does "GLP2-TZA" refer to?
GLP2-TZA is our catalogue designation for this research material. The compound is tirzepatide, development code LY3298176. CAS 2023788-19-2.
What does ≥99% HPLC purity mean?
High-performance liquid chromatography separates the sample into its components and measures each as a proportion of the total. ≥99% means the target peptide accounts for at least 99% of the material by that method. The chromatogram showing this is included in the lot’s COA.
Can I see the COA before ordering?
Yes. Sample documentation is on our COA page, and we will send the specific COA for any lot on request — before or after purchase.
Is this a drug product?
No. This material is supplied strictly as a research material. It is not a drug product and is not for human consumption.
How is this shipped?
Sourced and shipped within the United States, typically 2-day delivery. Lyophilized peptides are stable in transit; refrigerate on arrival.
What is the difference between the 10 mg and 30 mg vials?
Mass of lyophilized compound per vial. Both are the same material to the same ≥99% specification, with the same documentation. The 30 mg vial carries a lower cost per milligram.
Tirzepatide Purity & COA
Every lot is tested before release and ships with its own certificate of analysis. We publish the COA unredacted — including the lot number, the test date and the actual chromatogram — rather than a summary figure.
HPLC purity
High-performance liquid chromatography establishes purity against the ≥99% specification. The chromatogram is included in the COA, not just the resulting number.
Mass spectrometry
Identity is confirmed by mass spectrometry against the expected molecular weight of 4813.53 g/mol.
Lot traceability
Each vial’s lot number corresponds to a specific COA on file. Request the document for any lot you have received at any time.

Handling and storage
Supplied lyophilized. Standard laboratory handling for peptides of this class applies.
| Lyophilized storage | 36–46 °F short term; −4 °F for extended storage, protected from light |
|---|---|
| Reconstitution | Bacteriostatic water is the common choice for laboratory reconstitution. Add solvent slowly against the vial wall; do not inject directly onto the powder. |
| Mixing | Swirl gently until dissolved. Do not shake or vortex — mechanical agitation can shear peptide chains. |
| After reconstitution | Refrigerate at 36–46 °F. Avoid repeated freeze-thaw cycles. |
| Light | Protect from light at all stages. |
