About Tirzepatide
Tirzepatide is a dual GIP/GLP-1 receptor agonist widely used as a reference compound in metabolic research examining incretin receptor co-activation and its downstream effects on glucose-regulatory signaling pathways.
Laboratories use tirzepatide in comparative binding-affinity assays and cell-based signaling studies alongside single-target incretin agonists to characterize differential receptor activation profiles.
Each shipped lot is verified through independent third-party analytical testing, with a Certificate of Analysis published on our COA page.
Research Areas
- Dual incretin receptor signaling
- Glucose-regulatory pathway research
- Comparative receptor binding-affinity studies

Storage & Handling
- Store lyophilized vials at -20°C for long-term laboratory storage; short-term storage at 2–8°C is acceptable for materials in active use.
- Protect vials from light and repeated freeze-thaw cycles; aliquot before freezing where practical.
- Once a vial has been opened in a laboratory setting, use within the timeframe recommended by your institution's SOPs and document handling in your lab notebook.
- Keep sealed vials in a desiccated environment; humidity exposure can degrade lyophilized peptide material over time.
Testing & Quality
Each lot undergoes independent third-party HPLC/MS analysis. The current lot's COA is published on our COA page.

Research reference
Tirzepatide is a synthetic dual agonist at the GIP and GLP-1 receptors, characterized across the SURPASS and SURMOUNT clinical trial programs. Approved prescription products exist; research-grade material supplied for laboratory work is a separate, unapproved category.
