How to verify a Janoshik COA before trusting a peptide report.
A Janoshik logo or PDF is not enough. Verify the report at the lab source, match the compound and reported result to the record, then confirm the lot or batch identifier ties the report to the vial or order under review. A valid report for one sample does not automatically verify every vial, future lot, or supplier-wide claim.

Match the document fields
Confirm the compound identity, reported purity or assay result, task or report identifier, date information, and any lot or batch reference.
Tie the report to the vial
The source record still has to connect to the vial, supplier lot page, or order record under review. Authentic paperwork for one sample can be wrong-lot paperwork for another.
Keep the boundary clear
Janoshik verification can support supplier due diligence. It does not create a supplier-wide guarantee, future-lot guarantee, or human-use implication.
Fields that must match
The 90-second source check is field matching, not logo recognition.
Start at the lab source, then compare the resolved record against the supplier PDF and the vial or order record in front of you.
| Field | What to compare |
|---|---|
| Compound identity | The named peptide, sequence where available, or analyte should match the PDF and source record. |
| Result summary | Purity, assay, or identity result should match the source page rather than only a screenshot. |
| Report/task identifiers | Task numbers, report IDs, keys, or QR-resolved identifiers should align across the record. |
| Date context | Report and sample dates should be plausible for the lot being sold now. |
| Lot or batch reference | Any lot code shown should connect to the vial, supplier lot page, or order record. |
What verification does not prove
Authentic paperwork still has limits.
- A valid report for one sample does not verify every vial from a supplier.
- A valid report does not verify future lots, replacement lots, or relabeled batches.
- A source record does not replace the need to match the report to the exact lot under review.
- A third-party analytical report is not medical, dosing, treatment, or human-use guidance.
Titan-specific boundary: do not treat this educational page as a claim that every Titan lot is Janoshik-tested. Only a named report for a specific lot should be treated as a third-party report. For Titan, use the live lab-testing and lot-release documentation path unless a named lot report says otherwise.
FAQ
Short answers for source-checking this page.
These answers match the page-level FAQPage schema and stay inside research-use-only documentation due diligence.
Does a Janoshik logo prove a peptide COA is real?
No. Treat the logo as a prompt to verify, not as proof. The report should resolve through Janoshik's own public or verification route and match the document details.
Which fields should match between the PDF and source record?
Match the compound identity, reported purity or assay result, report/task identifiers, date information, and any batch or lot reference shown on the document.
Can a real Janoshik report still be the wrong report for a vial?
Yes. A report can be authentic but attached to a different batch. The batch or lot identifier must connect the report to the vial, order record, or supplier lot page.
Does Janoshik verification prove a peptide is suitable for human use?
No. This page is for research-use-only supplier due diligence. It does not provide medical, dosing, treatment, or human-use guidance.
Does Titan claim Janoshik testing on every lot?
Do not infer that. Only a named report for a specific lot should be treated as a third-party report. Otherwise, use Titan's live lab-testing and lot-release documentation path.
