Verify a batch

Take the lot number printed on your vial, type it below, and open the certificate of analysis for that exact production run. No account, no email address, no waiting for someone to send it to you.

You do not need to have bought anything from us to use this. If you are holding a vial and want to know whether its paperwork is real, that is exactly what this is for.

The lot number is printed on the vial label. The cap code and the laboratory accession number both work too.

What is published so far

9 certificates cover 8 compounds: GLOW, GLP, IGF1-LR3, MT2, Sermorelin, SS-31, Tesamorelin, Tirzepatide.

That is not the whole catalogue, and we are not going to pretend otherwise. Certificates go up as batches are tested and released. If the compound you want is not listed yet, ask us for its lot number and testing status before you order — we would rather answer that than have you assume.

Why this page exists

Nearly every research-peptide supplier says its products are independently tested. Far fewer will show you the certificate for the specific vial you are holding, and a good number will only send one after you have emailed them and explained who you are.

A purity claim you cannot check is a marketing line. A lot number you can look up, tied to a dated report from a named laboratory, is a record. We would rather be judged on the second kind.
