Public COA audit
KLOW · 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
- 88%
- Panels
- 5/7
- Purity (printed)
- 99.52%
Scored high because the document is mostly consistent but carries soft concerns, broad panel coverage (5/7), and 1 soft concern.

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.
5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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).
Confirmed (GHK-Cu + BPC-157 + TB-500 + KPV)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.52%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.7163 ppm, Cd: ND, Pb: ND, Hg: 0.8077 ppm, Cr: ND
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.
0.077 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.
Findings
Evidence-linked observations from this audit.
High purity with conformity testing
99.52% purity confirmed across three conformity samples (mean 99.51%, std dev 0.0125%), demonstrating batch consistency
Multi-component blend confirmed
All four peptide components (GHK-Cu, BPC-157, TB-500, KPV) confirmed present by HPLC retention time matching
Comprehensive testing panel
Includes purity, identity, heavy metals, sterility (PCR), endotoxin, and fentanyl screening. Missing only microbial count and residual solvents/water content
Clear batch identification
Lot CR-KLOW-80MG-2607-Black with COA number COA-2026-XLDPAB and accession ACC-2026-7832
Appropriate timeline
Received 2026-07-03, analyzed and issued 2026-07-10 (7-day turnaround)
ISO/IEC 17025 accredited lab
ILS Laboratories claims ISO/IEC 17025 accreditation with verification URL and QR code provided
Professional presentation
Well-structured two-page report with chromatogram, detailed methodology notes, and digital verification system
Fentanyl screening included
Immunoassay fentanyl screen (50 ng/mL cutoff) shows 'Not Detected' - unusual for peptide COAs but may reflect vendor's quality control practices
