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.
<0.05 EU/mL
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 contains only endotoxin testing results. No identity confirmation (MS, NMR, FTIR), purity (HPLC), heavy metals, microbial, sterility, or residual solvent/water panels are present. This appears to be a supplemental endotoxin-only report, not a comprehensive COA.
No purity data
No HPLC or other purity measurement is provided. Cannot assess compound purity from this document.
No identity confirmation
No mass spectrometry, NMR, or other identity verification method is documented. The compound identity is stated but not analytically confirmed in this report.
No sample date
Analysis date is provided (08/22/2026) but no sample collection or receipt date is documented.
Lab identification present
Testing lab identified as Horizon Analytical with contact information and verification URL. Signed by Aleksey Yevtodiyenko PhD, Research and Formulation Chemist.
Lot number present
Lot number DPS-6133020 clearly documented.
Professional presentation
Document has professional formatting with QR code for validation, clear layout, and appropriate disclaimers for research use.
