2 independent third-party assays of Snap-8, covering 2 vendors.
Measured purity across those assays runs from 99.8% to 99.8%, median 99.8%. The spread is the point: it is variation between lots and between vendors, not a single number that describes the compound.
Assay dates span 2024-08-05 to 2025-07-09.
Manufacturer recorded on the certificate: Eros Peptides.

A certificate of analysis describes the lot that was submitted and nothing else. It is not a guarantee about a later batch, and purity is not identity — a sample can assay clean and still be the wrong compound, or the right compound at the wrong concentration. Vendors with no assay row below have not been tested here, which is not the same as having failed.
