1. Reduced, not oxidised
The research-relevant form is reduced L-glutathione (GSH), CAS 70-18-8. Confirm the listing states the reduced form and the CAS — the oxidised form (GSSG) is a different molecule with different handling.
2. Purity and identity on the same record
A real COA shows the batch/lot number, HPLC purity, identity confirmation, the testing lab and the test date — on the same record as the lot you receive. For a widely commercialised molecule this is exactly where the difference between a research supplier and a generic seller shows up.
3. Check the COA against the batch number
The lot number on the vial must match the lot on the certificate, and the certificate should be checkable independently — enter the lot number on a public batch-verification page and the record comes back with the purity, identity and test date for that specific batch.
