Public COA audit
GHK-Cu
Audited September 5, 2026
Document structure and test panels align with what we expect from authentic lab reports.
- Legitimacy
- 95
- Confidence
- 95%
- Panels
- 5/7
- Purity (printed)
- 99.82%
Scored high because document structure and panels look consistent with authentic lab output and broad panel coverage (5/7).

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.
5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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).
Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.82%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
All Not Detected (As, Cd, Cr, Hg, Pb)
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.
0.096 EU/mL
Sterility
Tested · passed
Sterility testing where applicable.
No Growth
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.
High purity confirmed
99.82% purity by HPLC with conformity testing across 3 samples (mean 99.75%, std dev 0.0497%). Consistent results across batch.
Identity confirmed
GHK-Cu confirmed by HPLC retention time match with reference standard. Includes fentanyl screen (not detected).
Batch information complete
Lot CR-GHK-50MG-2606-1, COA COA-2026-SIOCJM, Accession ACC-2026-5028. Net peptide content 52.89 mg (labeled 50mg).
Lab credentials present
ILS Laboratories, San Diego CA. ISO/IEC 17025 accredited. Includes verification URL, access code N2U6677R, QR code, and lab director signature.
Comprehensive testing panel
Includes purity/identity (HPLC), heavy metals (ICP-MS), endotoxin (USP <85>), and sterility (PCR). Microbial and residual solvent panels not present but not required for all peptide COAs.
Professional presentation
Well-formatted 2-page report with clear tables, chromatogram, conformity testing data, methodology notes, and proper accreditation disclaimers.
