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.
0.0129 EU/µg
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.
Missing purity analysis
No purity testing (HPLC) reported. Essential for peptide quality assessment.
Limited testing scope
Only endotoxin and visual appearance tested. No heavy metals, microbial, sterility, or residual solvent testing.
No verification URL provided
Certificate number PCB-CA1043 listed but no URL or QR code for independent verification.
Professional presentation
Document has professional layout with clear branding, structured data tables, and detailed ENDOSAFE test record.
Reasonable timeline
Sample received 2026-07-10, analyzed and issued 2026-07-15. Five-day turnaround is plausible.
Batch information present
Lot number PPA-RL-CU100-R00227 clearly stated with manufacturer Peptaura-Retalux.
Missing critical identity testing
No identity confirmation (HPLC, MS, NMR) present. Cannot verify the compound is actually GHK-CU.
