Description
Tirzepatide research peptide
Tirzepatide (LY3298176) is a synthetic 39-amino-acid peptide that activates two incretin receptors: the glucose-dependent insulinotropic polypeptide receptor (GIPR) and the glucagon-like peptide-1 receptor (GLP-1R). Its backbone is based on the GIP sequence, with non-standard amino acids and a C20 fatty diacid attached through a linker, which supports albumin binding and extends its half-life. In the laboratory it is used to study combined GIP and GLP-1 receptor signalling.
Supplied as a lyophilised powder in 10mg and 15mg vials. The tirzepatide we supply is a research reagent for in vitro laboratory use only.

How tirzepatide compares
Quality and testing
Every batch is purity tested by Janoshik, an independent laboratory, using HPLC before it is released for sale. Read more about our process on the Quality & Testing page.
Storage and handling
Store the lyophilised powder at −20 °C, sealed and protected from light and moisture. Allow the vial to reach room temperature before opening to limit condensation. Lipidated peptides can adsorb to plastics, so follow your laboratory’s validated protocol for buffer choice and low-binding labware, using appropriate PPE.

Frequently asked questions
What is tirzepatide?
Tirzepatide (LY3298176) is a synthetic 39-amino-acid peptide that acts as a dual agonist at the GIP and GLP-1 receptors. A C20 fatty diacid attached to the chain supports albumin binding and extends its half-life.
How is tirzepatide different from retatrutide?
Tirzepatide is a dual GIP and GLP-1 receptor agonist. Retatrutide adds glucagon-receptor agonism, making it a triple agonist. Both are studied in research on incretin signalling.
Is tirzepatide a licensed medicine in the UK?
A tirzepatide medicine is licensed in the UK for prescription use. The tirzepatide we supply is a research reagent, not that medicine. It is sold strictly for in vitro laboratory research and is not for human or animal use.
What sizes are available?
Tirzepatide is available in 10mg and 15mg vials, supplied as lyophilised powder.
What purity is your tirzepatide?
Every batch is purity tested by Janoshik, an independent laboratory, using HPLC before it is released for sale.
How should tirzepatide be stored?
Store the lyophilised powder sealed at −20 °C, protected from light and moisture. Allow the vial to reach room temperature before opening. Stability in solution should be validated within your own laboratory protocol.
Do you ship tirzepatide from the UK?
Yes. Orders placed before 3PM UK time, Monday to Friday, are normally dispatched the same day by Royal Mail Tracked 24. See our Shipping Policy.
Do you provide dosing or usage advice?
No. Tirzepatide is supplied for in vitro laboratory research only. We do not provide dosage, administration or medical advice of any kind.
Research use only. This product is supplied strictly for in vitro laboratory research. It is not for human or animal use, and not for diagnostic or therapeutic purposes. By purchasing, you agree to our Research Use Disclaimer.
