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
- 88
- Confidence
- 92%
- Panels
- 3/7
- Purity (printed)
- 99.29%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), and 1 soft concern. To improve: include identity, purity, and endotoxin at minimum.

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 · 3 passed · 0 failed · 0 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).
KPV confirmed, [M+H]+ 343.03
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.290% (average of 99.243%, 99.255%, 99.374%)
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 · passed · core
LAL or chromogenic endotoxin assay.
≤ 0.05 EU/mL (both replicates)
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.

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
Average purity of 99.290% across three vials (99.243%, 99.255%, 99.374%) is excellent and consistent with high-quality research peptides. HPLC chromatogram shows clean single peak.
Mass spec confirmation
Mass spectrometry confirms KPV identity with [M+H]+ ion at 343.03 m/z, consistent with expected molecular weight. LCMS/MS method provides robust identity verification.
Endotoxin testing included
Endotoxin testing performed with two replicates, both passing at ≤ 0.05 EU/mL threshold. This is appropriate for research-grade peptides.
Batch information complete
Lot number CR-KPV010-2511-1 clearly stated. Net content measured for three vials (10.86, 11.04, 11.15 mg) with average 11.01 mg, close to labeled 10mg.
Dates appropriate
Received 2025-11-19, reported 2025-11-22 (3-day turnaround). Both dates are before the current date of 2026-09-05.
Lab identification present
Freedom Diagnostics identified with verification URL (FreedomDiagnosticsTesting.com), contact email ([email protected]), accession number (2511190433), and search code (Crus2511190433). Signed by Stephen Schmidt, Principal Chemist.
Limited panel scope
COA includes purity, identity, and endotoxin testing but lacks heavy metals, microbial, sterility, and residual solvent/water testing. This is common for basic research-grade peptide testing but represents a limited analytical scope.
Professional presentation
Document includes chromatogram, mass spectrum, product photos, and clear tabular data. Appropriate research-use-only disclaimer included.
