Public COA audit
GHK-Cu
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 88%
- Panels
- 1/7
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (1/7), 2 soft concerns, and notable note: "Endotoxin-only report". To improve: 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.
<5.00 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.

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 is specifically an endotoxin testing report (indicated by 'ENDO' in sample name). It does not include purity, identity, or other panels. This appears to be a split report focused solely on bacterial endotoxin testing per USP <85>.
Established testing laboratory
TrustPointe Analytics LLC is a known third-party testing laboratory in Michigan with verifiable contact information and online verification system.
Valid publication date
Published date of 2026-05-18 is before the current date of 2026-09-05 and is reasonable.
Client sample ID present
Client SID CU202605 and internal sample ID SPL-3755 are both documented.
Endotoxin testing complete
USP <85> bacterial endotoxin test shows <5.00 EU/mL with quality control metrics (CV%, spike recovery 96%) indicating proper test execution.
Professional presentation
Document includes QR code verification, dual signatures (President and Managing Director), and standard COA formatting.
No purity data in this report
This endotoxin-focused report does not contain HPLC purity or identity confirmation. A complete assessment would require the companion purity/identity COA for this lot.
