A COA is a starting point.
Context is the standard.
We look beyond whether a PDF exists. The useful questions are who performed the test, what sample was tested, when it was analyzed, what the result actually measured, and whether the record can be connected to the batch being referenced.
Identify the laboratory
We record the lab name, report/task identifier, report date, and any available verification link.
Confirm what was measured
Identity, purity, fill/quantity, sterility, endotoxin, and other tests answer different questions. One result should not be presented as proof of everything.
Connect the batch
A current, batch-specific report tied to the material being referenced is stronger than a generic historical report.
Record discrepancies
Failed tests, mismatched client names, missing lot numbers, stale reports, and retests remain part of the evidence trail.
Separate analytical evidence from medical claims
A laboratory result does not establish clinical safety, effectiveness, approval status, dosing, or suitability for human use.
Supplier Identity
Legal/trade names, representative identity, contact channels, warehouse claims, and company documents.
Batch Record
Compound, stated amount, lot/batch reference, testing lab, report number, test date, and verification notes.
Evidence Status
Confirmed, vendor-claimed, independently verified, unresolved, or contradicted — clearly distinguished.
