Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 95
- Confidence
- 92%
- Panels
- 5/7
- Purity (printed)
- 99.19%
Scored high because the document is mostly consistent but carries soft concerns, broad panel coverage (5/7), 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.
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).
GHK-Cu + KPV Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.19%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
All Not Detected (As, Cd, Cr, Hg, Pb)
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.
NMT 0.05 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 confirmed
99.19% purity by HPLC with conformity testing across 3 samples (mean 99.19%, std dev 0.0047%), demonstrating excellent batch consistency
Identity confirmed
Both GHK-Cu and KPV confirmed present by HPLC retention time match with reference standards
Comprehensive testing
Full QC panel includes purity, identity, heavy metals (ICP-MS), endotoxin (USP <85>), sterility (PCR), and fentanyl screening
Batch information complete
Lot number CR2604GHKKP60-01, COA number COA-2026-P0FPZZ, accession ACC-2026-3008 all clearly documented
Dates consistent
Sample received 2026-05-22, analyzed and issued 2026-06-05, reasonable turnaround time
Lab credentials present
ILS Laboratories claims ISO/IEC 17025 accreditation, provides physical address (8222 Vickers St, Suite 106, San Diego, CA 92111), phone (619) 329-3999, and verification portal
Professional presentation
Well-formatted 2-page report with chromatogram, conformity testing data, QR code for verification, and detailed methodology notes
Microbial panel absent
No microbial contamination testing (e.g., total aerobic count, yeast/mold) reported; sterility testing (PCR) is present but addresses different quality attribute
Residual solvents/water not tested
No residual solvent or water content analysis reported
