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
- 92
- Confidence
- 93%
- Panels
- 3/7
- Purity (printed)
- 99.9%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), and 2 soft concerns. 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.
3 of 7 present · 2 passed · 0 failed · 1 reported · 4 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).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
>99.9%
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 · result on file · core
LAL or chromogenic endotoxin assay.
0.98 EU/vial
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.
High chromatographic purity
HPLC purity >99.9% is excellent and normal for research-grade peptides.
Identity confirmed by MS
Mass spectrum matches reference standard for GHK-Cu (m/z 342 base peak consistent with expected molecular ion).
Batch/lot number present
Lot bnkauur clearly stated on certificate.
Dates are consistent and valid
Sample received 2026-01-16, testing performed 2026-01-26 to 2026-01-31, report issued 2026-02-04. All dates are logical and on or before 2026-09-05.
Reputable testing laboratory
Krause Analytical LLC is a known third-party analytical lab in Austin, TX. Signed by Mark C. Krause, Laboratory Director.
Verification URL provided
Certificate includes verification URL https://finnrick.com/verify with certificate ID bnkauur.
Endotoxin testing performed
Endotoxin result 0.98 EU/vial by USP 86 (LAL method). No explicit pass/fail limit stated, but value is low.
Heavy metals method described but no results
Page 3 describes ICP-MS method for metals (USP/NF 233), but no heavy metals results are reported on page 1. This may indicate metals testing was not performed for this lot, or results are in a separate report.
Microbial and sterility testing not performed
No microbial contamination or sterility testing results are present. This is common for non-sterile research peptides but limits the scope of quality assurance.
Professional formatting and documentation
Certificate includes chromatogram, mass spectrum comparison, detailed methods summary, and proper lab branding. Formatting is consistent with legitimate analytical reports.
