Also known as: LY3298176, GIP/GLP-1 RA

Key Facts

Tirzepatide is a weight management research peptide (C225H348N48O68, MW 4813.5 g/mol). Tirzepatide is a dual GIP and GLP-1 receptor agonist peptide studied for metabolic, glycemic, and body-composition research. It is supplied as a lyophilized powder for laboratory and in-vitro research use only — not for human consumption.

What is Tirzepatide?

Tirzepatide is a synthetic 39-amino-acid peptide engineered to act as a dual agonist at the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. By engaging both incretin pathways, it has been investigated in research models for effects on insulin secretion, glucagon suppression, gastric emptying, appetite signaling, and adipose tissue metabolism. It is frequently used as a comparator alongside GLP-1-only agonists such as semaglutide and triple agonists such as retatrutide in metabolic research. Supplied as a lyophilized powder for in-vitro and laboratory research use only; not for human consumption.

Tirzepatide Research Applications

In published and preclinical research, Tirzepatide has been studied across the following areas:

  • GIP/GLP-1 dual receptor agonist research
  • Glucose regulation and insulin sensitivity studies
  • Body composition and weight management research
  • Comparative incretin research

Tirzepatide in Research: Reconstitution & Study Concentrations

Tirzepatide is a dual GIP/GLP-1 receptor agonist studied extensively in the SURPASS and SURMOUNT clinical programs. In a laboratory setting the lyophilized peptide is reconstituted with bacteriostatic water; the working concentration is set by the solvent volume and the research model. Tirzepatide is not approved for human use in the form sold here and is supplied strictly for research.

Worked example: a 10mg vial reconstituted with 2 mL of bacteriostatic water yields 5.00 mg/mL.

Tirzepatide — Frequently Asked Questions

What is Tirzepatide?
Tirzepatide is a dual GIP and GLP-1 receptor agonist peptide studied for metabolic, glycemic, and body-composition research. It is supplied in 10mg vials and intended strictly for in-vitro and laboratory research use only.
How should Tirzepatide be stored?
Tirzepatide should be stored at -20°C for long-term storage or 2-8°C for short-term use. Keep the vial sealed and protected from light, moisture, and repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 30 days.
What purity is Tirzepatide?
Tirzepatide is manufactured to a minimum purity of ≥98% as verified by HPLC analysis, with identity confirmed by mass spectrometry. Each batch ships with a Certificate of Analysis (COA).
What is the recommended reconstitution protocol for Tirzepatide?
For this 10mg vial, add 2 mL of bacteriostatic water to yield a concentration of 5.0mg/mL. Draw 10 units on a 1mL insulin syringe for a 0.5 mg dose. Inject BAC water slowly along the inner vial wall — do not shake. Allow the powder to dissolve fully (2–5 minutes). Administer in the AM, 3 times per week. Refrigerate reconstituted solution at 2–8°C and use within 30 days.
Is Tirzepatide legal to buy for research?
Tirzepatide is sold in the United States as a research chemical for laboratory and in-vitro use only. It is not approved by the FDA for human use and is not sold for human consumption. Researchers are responsible for compliance with all applicable federal, state, and institutional regulations.
How is Tirzepatide reconstituted for research use?
Tirzepatide ships as a lyophilized (freeze-dried) powder and is reconstituted with bacteriostatic or sterile water before use in research. The volume of solvent added determines the working concentration — use the Elyte reconstitution calculator to derive the exact concentration for a given vial size and solvent volume.
Does Tirzepatide come with a Certificate of Analysis?
Yes. Every batch of Tirzepatide from Elyte Peptides ships with a third-party Certificate of Analysis (COA) documenting identity and HPLC purity (≥98%), so research results can be traced to a verified lot.
