How should I store my peptides upon arrival?

Store unopened vials at -20°C for maximum shelf life. Once reconstituted, refrigerate at 2-8°C and use within 30 days. Keep away from direct light and avoid freeze-thaw cycles.

What is the shelf life of a reconstituted peptide?

Reconstituted peptides should generally be used within 28-30 days when stored at 2-8°C. Unreconstituted lyophilized peptides can last 24+ months when stored at -20°C.

Do you ship internationally?

Yes, we ship to 50+ countries from our US and Hong Kong warehouses. Average delivery time is 3 business days with cold-chain packaging. Customs compliance documentation is included.
