VendorInvestigate is a review service that examines supplier documentation, corporate registration and supply-chain claims. Unlike Janoshik Analytical and Medutest, it does not perform analytical determinations; unlike PeptideMeter, it does not aggregate test results into statistics. Its object of study is the paperwork and the provenance rather than the material.[1]
Documentary review answers questions that analysis cannot. Whether a batch number on a vial corresponds to a record the supplier can produce, whether a claimed certification exists and is current, whether an organisation is registered where it says it is — none of these is determinable by injecting a sample onto a column.[1]
It also cannot answer questions that analysis can. A complete and internally consistent document set is not evidence that the material matches it. The two kinds of evidence are complementary and neither substitutes for the other.
What documentary review examines
[edit]The typical scope covers corporate identity and registration, the existence and currency of claimed certifications, the internal consistency of certificates against the lots and dates they name, and the correspondence between what a catalogue lists and what can actually be ordered.[1]
Internal consistency is the most productive of these. A certificate carries several fields that must agree with each other and with the vial: the lot identifier, the manufacture and retest dates, the method conditions, and the reported determinations. A certificate whose stated method could not produce the reported figure, or whose retest date precedes its manufacture date, is defective on its face without any laboratory work at all.[2]
Registration and certification claims are checkable against public registers. A claimed GMP certification names an issuing body, a scope and a validity period, and a claim without those particulars is not checkable — which is itself an observation about the claim.[3]
