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.
1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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
Not on this COA · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Purity
Not on this COA · core
Reported purity percentage for the analyte.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Tested · passed · core
LAL or chromogenic endotoxin assay.
<0.05 EU/mL
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.
Issue date after sample date
Analysis conducted date (03/29/2026) is 5 days before the received date (04/03/2026), which is logically impossible
Missing critical panels
COA only includes endotoxin testing. Missing identity confirmation, purity analysis (HPLC/MS), heavy metals, microbial, sterility, and residual solvent/water content panels that are standard for peptide research compounds
No purity data
No HPLC, MS, or other purity analysis provided. Purity is a fundamental requirement for peptide COAs
No identity confirmation
No MS, NMR, or other identity confirmation method documented. Cannot verify the compound is actually GHK-Cu
Lab contact information provided
Horizon Analytical with contact email and verification URL provided. Includes QR code for validation
Professional presentation
Document has professional layout with clear headers, compound identification (CAS, formula, molecular weight), and signatory information
