How to store Cagrilintide

Lyophilised (freeze-dried) storage

Unreconstituted Cagrilintide, like most research peptides, is stable when stored in its original sealed vial at -20°C for long-term storage. For short-term use (under 3 months), refrigeration at 2-8°C is acceptable. The vial must be protected from direct light and moisture.

Peptify dispatches Cagrilintide in temperature-tolerant packaging from the UK, usually arriving within 24-48 hours of dispatch.

After reconstitution

Once Cagrilintide is reconstituted with bacteriostatic water (BAC water, 0.9% benzyl alcohol), the solution should be stored at 2-8°C (refrigerated) and used within 28 days. Bacteriostatic water's preservative system inhibits microbial growth for roughly four weeks after first puncture — significantly longer than sterile water, which must be used immediately.

Avoid freeze-thaw cycles. Never leave the vial at room temperature for extended periods, and keep it in its original rubber-stoppered vial to minimise contamination risk.

Shelf life and quality verification

Peptify publishes a batch-specific expiry date on every Cagrilintide COA, alongside HPLC chromatogram data and mass spectrometry confirmation. The full Certificate of Analysis for your specific batch is downloadable from the product page.
