Public COA audit
GHK-Cu
Audited September 5, 2026
Multiple signals on this document conflict with known lab formats or verification patterns.
- Legitimacy
- 15
- Confidence
- 92%
- Panels
- 2/7
- Purity (printed)
- 99.816%
Scored poorly because audit signals point to fabrication or reused paperwork, limited panel coverage (2/7), 3 critical findings, and notable note: "Non-existent testing laboratory". To improve: replace this file with an original lab certificate that verifies on the lab portal 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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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
Tested · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
GHK-Cu confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.816%
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
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.
Non-existent testing laboratory
Freedom Diagnostics and FreedomDiagnosticsTesting.com do not correspond to any known accredited peptide testing laboratory. No verifiable business registration, accreditation records, or independent references found for this entity.
Unprofessional document quality
Document exhibits multiple formatting irregularities: inconsistent spacing, amateur layout, generic stock photo of vials with visible 'GHK-Cu' label (unusual for analytical lab documentation), and overall presentation inconsistent with established testing laboratories.
Suspicious contact information
Contact email '[email protected]' uses generic admin address rather than professional laboratory contact structure. Domain registration and web presence cannot be independently verified as legitimate analytical laboratory.
Minimal mass spectrometry data
Mass spectrum shows only two peaks ([M+2H]2+ at 171.10 and [M+H]+ at 341.05) without comprehensive fragmentation pattern, isotope distribution, or detailed spectral analysis typical of rigorous identity confirmation.
Limited testing scope
COA only includes purity and identity testing. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water analysis. While not automatically disqualifying, this is minimal for research-grade peptides.
Generic disclaimer language
Disclaimer text appears boilerplate and generic, lacking specific laboratory accreditations, certifications, or regulatory compliance statements typical of established testing facilities.
Lot number present
Lot number 665394 is clearly stated.
Dates within acceptable range
Received date 2026-04-06 and reported date 2026-04-07 are both before today (2026-09-05) and show reasonable 1-day turnaround.
