For laboratory purchasing, the most useful shipping documents are those that support identity, traceability, and receipt verification.

Common documents to review

  • Certificate of Analysis (COA): Typically includes peptide name, batch number, test methods, and reported purity or assay data.
  • Packing slip or invoice: Confirms the ordered item, quantity, and batch reference when available.
  • Chain-of-custody or dispatch record: Helpful for documenting movement from supplier to laboratory.
  • Shipping label details: Should match the package contents and show any special handling requirements used during transit.

On receipt, laboratories should check that the document identifiers match the physical label and packaging, and that the lot or batch information is consistent across records. If cold-chain or controlled-temperature transport was required, the shipment record should indicate how conditions were maintained.

Reminder: research peptides should be handled and used only for laboratory research and are not intended for human consumption.
