Verify a research peptide batch

Where to find the lot number

The lot number is printed on the vial label of every product we supply, and it also appears on the certificate of analysis for that batch and on the order confirmation. It is a short alphanumeric code — enter it exactly as printed. The lookup ignores letter case and spaces, so hyphens and characters matter more than capitalisation.

What the lookup returns

For a released lot, the record shows the product name and vial size, the RP-HPLC purity result, the identity result where reported, the testing laboratory, the test date, and the storage conditions recorded for that batch. Where a certificate of analysis has been published for the lot, a downloadable copy of the COA is linked directly from the record, so the document behind the result can be reviewed in full.

Checking a specific product?

Every listing shows the batch and documentation status for the material supplied — see the GLP-3 (RT) 40mg research peptide, GLP-3 (RT) 10mg research peptide and GHK-Cu 50mg copper peptide listings.

If a lot number does not resolve

First check the number against the vial label for transcription errors — lot numbers are matched exactly. New batches are published as their certificates clear documentation review, so a very recent lot may not be live in the lookup yet. If a lot still does not resolve, email orders@indexpeptides.uk with the lot number and we will confirm its status and supply the certificate of analysis directly.

Published batches

Every record above shows the testing laboratory, its task ID, the test date and the published COA. The full set is on the lab results page.
