Public COA audit
KPV
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
- 2/7
- Purity (printed)
- 99.45%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 4 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).
KPV confirmed, [M+H]+ 343.08
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.45%
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
99.45% purity by HPLC is excellent and typical for research-grade peptides. Clean chromatogram with single dominant peak at retention time ~1.9 min.
Mass spec confirmation present
Mass spectrum shows [M+H]+ ion at m/z 343.08, consistent with KPV tripeptide (Lys-Pro-Val, theoretical mass ~342 Da).
Lot number present
Lot KPV09032025-J clearly stated with net peptide content 9.75 mg.
Recent testing dates
Received 9/9/2025, reported 9/10/2025. Both dates are valid and on or before the current date (2026-09-05).
Lab verification unclear
Freedom Diagnostics claims USA operation with website FreedomDiagnosticsTesting.com and email [email protected]. 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 panels present. This is common for basic purity-focused reports but limits safety assessment.
Generic template appearance
Document uses a simple template with stock product photos. While not inherently problematic, the presentation is less detailed than reports from established third-party labs (e.g., no detailed method parameters, no QC standards, no accreditation logos).
Signatory credentials
Stephen Schmidt listed as Principal Chemist with signature, but no professional credentials (PhD, certifications) or lab accreditation information provided.
