TIRZEPATIDE research vial by Regent Peptides

Research compound

Tirzepatide

£60.00/ 10mg vial

Dosage

Dual GIP / GLP-1 receptor agonist peptide, 39 amino acids

Tirzepatide is a synthetic 39-amino-acid peptide engineered on a GIP (glucose-dependent insulinotropic polypeptide) backbone with activity at both the GIP and GLP-1 receptors. It carries a C20 fatty diacid moiety attached via a linker at lysine 20, which gives the molecule its extended half-life in published pharmacokinetic literature. It is one of the most heavily studied incretin-class peptides of the last five years.

Regent Peptides supplies tirzepatide as a lyophilised powder in sealed vials across seven strengths, each batch manufactured in the UK and released only after independent HPLC purity analysis and mass spectrometry identity confirmation. The batch number on your vial links to its Certificate of Analysis.

In the research literature tirzepatide is studied in the context of incretin receptor pharmacology, glucose homeostasis models, energy balance and adiposity in preclinical systems, and comparative work against single-receptor GLP-1 agonists such as semaglutide. Supplied for laboratory research use only.

Research Handling Guidance

Before reconstitution, allow both the lyophilised peptide and your chosen diluent to settle at normal laboratory room temperature. Equalising temperatures in this way supports the structural stability of the compound while it goes into solution.

Diluents and reconstitution solutions are purchased separately.

Tirzepatide questions

What is the difference between tirzepatide and semaglutide in research?
Semaglutide is a single-receptor GLP-1 agonist; tirzepatide is engineered to act at both the GIP and GLP-1 receptors. Much of the comparative literature examines what the additional GIP activity contributes in receptor-signalling and metabolic models.
How is tirzepatide tested?
Each production batch is sent for independent HPLC purity analysis and mass spectrometry identity confirmation by Janoshik Analytical. The batch reference printed on the vial links to its Certificate of Analysis, which can be viewed on the lab's own verification site.
How is tirzepatide supplied?
As a sterile lyophilised (freeze-dried) powder in a sealed glass vial, available in seven vial strengths. Vials are labelled with compound name, strength and batch reference and are dispatched in plain, tracked packaging from the UK.
How should the lyophilised vial be stored?
Unopened lyophilised vials should be kept refrigerated at 2–8 °C, or at −20 °C for long-term storage, protected from light. Once reconstituted, solutions should be refrigerated and used within the period appropriate to the laboratory's own stability data.
Is this for human use?
No. All Regent Peptides products are supplied strictly for in-vitro laboratory research. They are not medicines and are not for human or veterinary use, diagnosis or treatment.
