Batch Verification
How to verify a VaultLabs lot
Match the lot printed on a VaultLabs vial to the published Certificate of Analysis — and what to do when the portal has no record yet.

What you are matching
Verification is a three-way check: the printed lot on the vial, the lot on your packing list or invoice, and the record in batch verification or COA search.
A PDF forwarded by email that does not share that lot identifier is not a substitute. How to read a peptide COA explains the fields once you have the right document.
On receipt
Enter the lot exactly as printed. Confirm product name and strength match the SKU you ordered.
If the portal shows a record, file the PDF against that lot in your inventory system before the vial is released to a working fridge.
When nothing is online
A missing record usually means analytical release or upload is still pending. It is not automatic evidence the lot failed.
Laboratories that require a published COA before release should request the lot by identifier through documentation request and hold the unit in quarantine until the record appears.
When the record and the vial disagree
Stop and quarantine before anything is opened. The usual causes are mundane — a transposed character, a strength that does not match the SKU ordered, or a COA issued for an adjacent lot from the same campaign — but all of them are resolved by asking, not by assuming.
Record what you observed: the exact string on the label, the string on the portal record, the packing list, and the date. Raise it through documentation request with the lot identifier. A discrepancy reconciled verbally and never written down is the version an auditor will question later.
Do not accept a substitute document for a different lot as closing the gap. Either the record for the vial in your hand is published, or the unit stays in quarantine under your SOP.
What verification does not prove
A published COA does not make the material suitable for human use, and it does not replace your laboratory’s incoming qualification SOP.
Document type (supplier vs third-party) is labelled on each published record when that distinction is disclosed. Interrogating that label from a purchasing seat — which laboratory issued the report, who selected and submitted the sample, and whether the panel covered identity as well as purity — is covered in third-party testing and peptide suppliers.
Verification is also a point-in-time check. It confirms a record exists for that lot, not that the vial was transported or stored correctly before it reached you — that is what your receiving log and the storage guide are for.
After the lot matches
Walk the fields with how to read a peptide COA or the COA receiving checklist. A common worked case is BPC-157 10 mg — identity and storage notes are on the BPC-157 monograph.
Reconstitution math is a separate step. Use the peptide reconstitution calculator only after the lot is accepted.
