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
- 75%
- Panels
- 1/7
Scored poorly because the file is incomplete or not a full COA, limited panel coverage (1/7), 1 critical finding, 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 only contains endotoxin testing results. No identity confirmation (MS, NMR), purity (HPLC), heavy metals, microbial, sterility, or residual solvent/water panels are present on this document. This appears to be a split/supplemental report focused solely on endotoxin testing.
Analysis date precedes sample receipt
Analysis conducted date (03/29/2026) is listed as 5 days before the received date (04/03/2026). This temporal inconsistency suggests either a data entry error or mislabeling of dates.
Limited verifiable information
While the lab name 'Horizon Analytical' and website 'horizonanalytical.com' are provided, there is no physical address, accreditation information, or detailed methodology disclosed. The QR code and verification URL cannot be validated from this static image.
Minimal technical detail
The endotoxin test result lacks method specification (LAL, chromogenic, gel-clot), equipment details, or reference standards. Professional COAs typically include more methodological transparency.
Lot number present
Batch/lot number APR-1676642 is clearly stated and matches the client's lot designation.
