Short answer
Verify a third-party peptide report against the issuing laboratory's own record. Compare the task number, verification key or QR destination, client, manufacturer, sample, dates, methods, results, and signature. Keep the original file unchanged.
If a supplier has rebranded, document the brand relationship separately instead of editing historical laboratory fields.
Key facts
- The issuing laboratory is the authoritative source for its report.
- A QR code should resolve to the expected laboratory domain and matching record.
- The online record and displayed report should agree on substantive fields.
- Brand migration notes should be separate from the original certificate.
- A screenshot without a verifiable task or report number provides weaker evidence.
Check the source before the result
Identify the laboratory and navigate to its verification service independently when possible. Do not rely only on a link supplied in an image. Confirm the domain, transport security, task or report number, and whether the verification page is controlled by the issuing laboratory. Save the original file and the date on which verification was performed.
Compare every identifying field
Match the task number, client, manufacturer, sample description, batch, test dates, methods, numerical results, comments, and signature or approval details. A mismatch can be a clerical issue, an amended record, a recycled report, or an altered image. Treat it as unresolved until the laboratory or supplier provides a documented explanation.
Handle rebranding transparently
When a supplier changes brand, a historical report may correctly show the former brand. Keep that report intact and add a separate statement such as 'Legacy report issued before the Vesta rebrand; original laboratory record remains unaltered.' If the report itself must show the new name, request an amendment or reissue from the laboratory.
Retain an audit-friendly record
Store the original report, verification evidence, supplier mapping to the current batch, reviewer, date, and disposition. Avoid destructive image editing, cropped verification fields, replacement QR codes, or recreated signatures. Transparency preserves both the scientific evidence and the supplier's credibility.
Frequently asked questions
Can a reseller place a new logo over a third-party laboratory report?
A separate frame or caption can identify the reseller, but it should not obscure or change the original report. The derivative should be clearly labeled and the original should remain available.
What if the QR code no longer works?
Use the report number or verification key through the laboratory's official site and contact the laboratory when the record cannot be confirmed.
