Record the product code and lot number.
Start with the exact product name or code, the listed amount and unit, and the lot or batch number shown on the label. A product code identifies the listing or variant. The lot number identifies a particular batch. Two vials with the same product code and listed amount may come from different lots.
Match the label to a Certificate of Analysis.
- Check the material and variant. Compare the label with the product information and the report’s description.
- Check the lot or sample ID. Match the label’s lot number to the report. If the lab uses a different sample code, ask the supplier for the documented link between the two.
- Keep the full report. Save the report number, issuer, date, and results with your lot record. If a label’s QR code opens a product page, check which report applies to your lot.
Then use the peptide COA reading guide to review the methods, units, and reported results. Consult the Safety Data Sheet for hazard and handling information.
Looking up a short code like GLPtz?
Short codes can vary by supplier or across label versions. Start with the exact spelling shown on your label or order record. Ask the supplier to confirm the material and applicable report using the product code and lot together. For an Everyday Peptides label, email info@everydaypeptides.ltd with both identifiers and the report number if available.
