Public COA audit
GHK-Cu · KPV
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 2/7
- Purity (printed)
- 99.789%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "High purity confirmed". 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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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/BPC-157/Thymosin Beta-4 confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.789%
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
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 purity confirmed
99.789% purity by HPLC-UV is within normal range for research-grade peptides and is supported by chromatogram showing clean separation of four peptide components
Mass spec confirmation present
Mass spectrometry data shows expected m/z values for all four peptides (GHK-Cu, KPV, BPC-157, TB4) with labeled peaks matching theoretical masses
Dates are valid
Received 2026-04-06, reported 2026-04-07 - both dates are before today (2026-09-05) and show reasonable 1-day turnaround
Lab verification limited
Freedom Diagnostics provides a verification URL (FreedomDiagnosticsTesting.com) and search code (Blan2604060227), but independent verification of lab accreditation/credentials not possible from document alone
Limited testing scope
This COA only covers purity and identity testing. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is included in this report. This is common for purity-focused reports but limits comprehensive quality assessment
Batch information present
Lot number 665394 clearly stated with net peptide content breakdown for all four components
Minor formatting inconsistencies
Date format inconsistent (04/06/2026 vs 04/7/2026 - missing leading zero on day). Product photos show vials but no direct lot number visible on vials in image
