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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.28%
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Microbial
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Sterility
Not on this COA
Sterility testing where applicable.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High purity confirmed
UPLC analysis shows 99.28% purity, exceeding the >98% specification. This is normal for research-grade peptides.
Identity confirmed by UPLC/MS
Compound identity verified as KPV using UPLC/MS with mass spectrometry data showing expected molecular ion peaks (341.51 m/z visible in MS spectrum, consistent with protonated form).
Batch information complete
Lot number B-4451178-P clearly stated with quantity measured at 10.15mg (spec: 10mg).
Dates are valid and logical
Lab received date 05/08/2026, analysis conducted 05/19/2026. Both dates are before today (2026-07-28) and show appropriate 11-day turnaround time.
Lab identification present
Horizon Analytical identified with contact email, verification URL (horizonanalytical.com), and signed by Aleksey Yevtodiyenko PhD, Research and Formulation Chemist.
Limited testing scope
Only identity and purity panels performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic research peptide COAs but limits comprehensive quality assessment.
Professional presentation
Document includes QR code for validation, chromatograms (UPLC and MS), proper chemical identifiers (CAS 112965-21-6, PubChem CID 9929972, molecular formula C17H32N6O4), and clear specification vs. result table.
