Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 6/7
- Purity (printed)
- 99.766%
Scored high because the document is mostly consistent but carries soft concerns, broad panel coverage (6/7), and 2 soft concerns.

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.
6 of 7 present · 6 passed · 0 failed · 0 reported · 1 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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.766%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
All Negative (As, Cd, Pb, Hg)
Microbial
Tested · passed
Bioburden / microbial limits testing.
No Growth
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
Pass (≤0.5 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.
