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).
Conform (appearance, solubility)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.5%
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
Tested · passed
Residual solvents or water content limits.
Water: 4.1%, Acetic Acid: 8.2%
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 HPLC purity
99.5% peptide purity by HPLC with 0.5% total impurities and 0.5% largest single impurity, all within specification
Identity tests present
Appearance and solubility tests conform to specifications
No laboratory identification
Document lacks testing laboratory name, address, accreditation information, or contact details
No verification mechanism
No URL, QR code, or reference number provided for independent verification of results
Limited testing scope
Heavy metals, microbial, endotoxin, and sterility testing not performed or reported
Dates consistent
Production date (2024-02-16), survey date (2024-02-28), and retest date (2026-02-15) are all logically consistent
Batch information present
Batch number 2024030601-1 with CAS number 1627580-64-6 and molecular formula provided
Watermark present
Document contains 'Denpeptides' watermark suggesting this may be a sample/template or vendor-specific format
Timing & next steps
Practical follow-ups based on document age and gaps.
