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).
Cortagen
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.82%
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
99.82% purity by LC-MS exceeds specification of >98%, with clean chromatogram showing single major peak
Identity confirmed
Compound identified as Cortagen by LC-MS with mass spectrum showing expected molecular ion at m/z 431.1775 (consistent with stated molecular weight 430.17 g/mol)
Batch/Lot number missing
No batch or lot number provided on the COA, which is standard practice for traceability
Dates reasonable
Sample received 03/20/25, analysis conducted 03/28/25 - 8 day turnaround is reasonable
Lab information present
BioRegen identified as testing lab with analyst name (Dr. Roberto Marin), contact information, and verification URL provided
Limited testing scope
Only identity and purity testing performed; no heavy metals, microbial, endotoxin, sterility, or solvent/water content testing
Professional presentation
Document includes chromatograms, mass spectrum, PubChem reference, QR code, security key, and professional formatting
Timing & next steps
Practical follow-ups based on document age and gaps.
