Public peptide testing registry
Independent laboratory reports on peptide samples that can be re-checked at the laboratory’s own verification page. The table records what the laboratory reported, not what any vendor claims. Nothing is scored or compared.
| Laboratory | Report no. | Compound | Labeled spec. | Reported purity | Reported content | Analysis date | Verification link | Pepti lot code printed? | Submitted by |
|---|---|---|---|---|---|---|---|---|---|
| Janoshik Analytical | 210105 | Retatrutide | 20 mg | 99.837% | 19.52 mg | 2026-10-07 | verify.janoshik.com · key CZU2DSY2SYYQ | No — the report's Batch field carries a contact handle, not a PEP-format lot code. Client and Manufacturer fields name peptioem.com. | Pepti (peptioem.com) |
Inclusion rules
- The report must be verifiable on the laboratory’s own website (a record page, a verification code lookup, or a signed PDF served by the laboratory). Screenshots, PDFs hosted by a vendor, or reports sent by email do not qualify on their own.
- The entry records only what the laboratory printed: compound, labeled specification, result, date, and whether the report identifies the client, the manufacturer and a lot code.
- Entries are sample-specific. A single report says something about one submitted sample; it is not evidence about a product line, a lot that was not tested, or a vendor in general.
- Reports are not removed when a result is unfavorable. If a laboratory withdraws or corrects a report, the row is annotated, not deleted.
- The registry does not accept payment for inclusion and does not rank laboratories or vendors.
Column notes
- Reported purity is the chromatographic purity figure printed by the laboratory, usually area-percent from HPLC. It is not the same as content.
- Reported content is the measured quantity of peptide in the vial, where the laboratory reports one, compared with the labeled specification.
- Pepti lot code printed? records whether a manufacturer lot code in the PEP-format appears on the report itself, so readers can tie the report to a public COA record. “Not confirmed” means Peptiledger could not read a lot code on the report image.
Submitting a report
Send the laboratory’s verification link (not a screenshot), the compound and labeled specification, and who submitted the sample to contact@peptioem.com. Reports on any manufacturer’s samples are accepted under the same rules. Reports that identify a Pepti lot code are cross-linked to the matching record at peptioem.com/coa; reports on other manufacturers’ samples are listed with the information the laboratory printed.
Read how to arrange independent testing and read a Janoshik report before submitting a sample, so the report carries enough identifying information to be useful.
