09 — Verification
How to verify a third-party peptide CoA
Verification is a match test, not a feeling. The CoA belongs to the vial only if product identifier, batch number, and testing laboratory line up with the bottle in hand.
Answer. File the PDF. Confirm batch match. Do not treat a third-party test as FDA approval.
Seven-point verification
| # | Check | Pass looks like | Fail looks like |
|---|---|---|---|
| 1 | Product identifier | Same name / code on vial and CoA | A nearby analog or a prior batch’s file |
| 2 | batch number | Exact string match | Truncated batch numbers, transposed digits, “representative” CoA |
| 3 | Testing laboratory | Named lab on the report letterhead | No lab name, or a screenshot with no letterhead |
| 4 | Analysis date | A date that can sit in the batch file | Undated page or no retest after a long gap |
| 5 | Identity method | MS or equivalent stated | Purity only, offered as identity |
| 6 | Purity method | HPLC (or equivalent) plus wavelength if given | A bare % with no method |
| 7 | File integrity | Searchable PDF kept with the original filename | Cropped image in a chat thread as the only record |
What “independently tested” means here
Emerald Tides provides batch-level analytical documentation supported by independent third-party testing where applicable. That is a record of selected parameters for that batch. It is not authorization, clearance, certification, or endorsement by the FDA.
Short questions
- Can one CoA cover every vial of that product name?
- No. CoAs are batch-specific.
- Is a supplier-hosted gallery enough?
- Only if the batch on the page is the batch on the vial and the PDF is saved into the batch file.
