Peptide certificates of analysis
A lot-level index of every published certificate. All certificates are issued by independent third-party laboratories (Janoshik Analytical and Freedom Diagnostics). Open any certificate to verify it against the issuing laboratory's own record. See our laboratory COA checklist and how to read a peptide COA. Research Use Only — not for human or veterinary use.

| How to use a certificate | Match the lot or batch on your vial to the certificate, then verify the report with the issuing laboratory |
How to verify a certificate
- Find your vial's lot or batch number on the label.
- Open the matching certificate below and confirm the same lot or batch is printed on it.
- Note the issuing laboratory and the accession number (Janoshik task number and unique key, or Freedom Diagnostics COA number).
- Verify that record directly with the laboratory, by typing its address yourself rather than following a link from a file.
- Compare compound, lot, date and result field by field, then file the certificate with your receiving record.
Frequently asked questions
How do I verify a Hermetica certificate of analysis?
Verify it with the issuing laboratory, not with us. For Janoshik reports, enter the task number and unique key at janoshik.com under Verify. For Freedom Diagnostics reports, quote the COA number to Freedom Diagnostics. Then check that the lot on the report matches the lot on your vial.
Which Hermetica products have a published COA?
BPC-157 10mg, TB-500 10mg and MOTS-c 10mg (Janoshik Analytical), and GHK-Cu 50mg and 100mg and Retatrutide 5mg and 10mg (Freedom Diagnostics).
Why do Epitalon and DSIP have no certificate?
No third-party certificate is published for the current Epitalon and DSIP lots. We do not list a certificate for a lot we cannot link to an issuing laboratory's record.
Does a COA cover every vial of that product?
No. A certificate describes the lot that was tested. It covers your vial only if the lot or batch number on your label matches the one on the certificate.
What does the purity figure on a COA mean?
It is the share of the target peptide among components detected by HPLC in the tested sample. It is not the mass of peptide in the vial, which is a separate content measurement.
