Public COA audit
GHK-Cu
Audited September 5, 2026
Missing panels or key metadata — not enough evidence to treat this as a full certificate.
- Legitimacy
- 45
- Confidence
- 82%
- Panels
- 1/7
Scored poorly because the file is incomplete or not a full COA, limited panel coverage (1/7), 3 critical findings, and notable note: "Endotoxin-only report". To improve: upload the full certificate (or the matching sibling purity/endotoxin report) and include identity, purity, and endotoxin at minimum.

Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
1 of 7 present · 1 passed · 0 failed · 0 reported · 6 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Not on this certificate file · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Purity
Not on this certificate file · core
Reported purity percentage for the analyte.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Microbial
Not on this certificate file
Bioburden / microbial limits testing.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
Pass (Replicate 1 and 2)
Sterility
Not on this certificate file
Sterility testing where applicable.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Residual solvent / water
Not on this certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
Endotoxin-only report
This COA only reports endotoxin testing results. No purity percentage, HPLC chromatogram, identity confirmation data, or other analytical panels are present. The document mentions LCMS/MS in the disclaimer but provides no actual purity or identity results.
No purity data
Despite claiming peptide purity analysis was conducted using LCMS/MS, no purity percentage or chromatogram is shown.
No identity confirmation
No mass spec data, retention time, or other identity confirmation is provided for GHK-Cu.
Limited scope
This appears to be an endotoxin-only report. The vendor may issue separate reports for purity/identity testing. Customers should request the complete analytical package.
Lot number present
Lot 665394 clearly identified.
Dates present and valid
Received 2026-04-06, reported 2026-04-07. Both dates are before today (2026-09-05) and show reasonable turnaround.
Lab verification unclear
Freedom Diagnostics claims USA operation and provides a website (FreedomDiagnosticsTesting.com) but independent verification of this lab's accreditation or reputation is recommended.
Minimal data presentation
The report format is sparse, with only pass/fail endotoxin results and a product photo. No numerical endotoxin values (EU/mg) or detailed methodology are shown.
