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
- 2/7
Scored poorly because the file is incomplete or not a full COA, limited panel coverage (2/7), 2 critical findings, and notable note: "No verification URL or contact info". 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.
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
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
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.007 ppm, Cd: <0.001 ppm, Hg: <0.001 ppm, Pb: 0.013 ppm
Microbial
Tested · passed
Bioburden / microbial limits testing.
Total Aerobic: <100 cfu/g, Coliforms: <10 cfu/g, E.coli: Absent, Salmonella: Absent, Staph: Absent, Yeast/Molds: <100 cfu/g
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.
No verification URL or contact info
The COA does not provide a website, phone number, or QR code for independent verification of results.
Issue date valid
Issue date of 2025-07-15 is before the current date (2026-09-05) and is legitimate.
Lot number present
Lot number L1164 is clearly stated.
Heavy metals and microbial testing present
Comprehensive heavy metals (USP 233) and microbial (USP 2021/2022) testing with passing results.
No purity testing
This COA lacks any HPLC, MS, or other purity/identity verification for the peptide GHK-CU. Only physical appearance, flavor, heavy metals, and microbial testing are present.
No identity confirmation
No mass spectrometry, NMR, or other analytical method confirming the molecular identity of GHK-CU is documented.
Missing endotoxin testing
No endotoxin (LAL/BET) panel is present. This is important for injectable or research-grade peptides.
Missing residual solvent/water content
No residual solvent or water content testing is documented.
Timing & next steps
Practical follow-ups based on document age and gaps.
