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).
Metformin
Purity
Tested · passed · core
Reported purity percentage for the analyte.
100%
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.
Missing Batch/Lot Number
The Batch/Lot # field is completely blank, which is unusual for a legitimate COA as batch traceability is fundamental to quality control.
Inconsistent Contact Information
The analyst contact email is '[email protected]' while the verification URL is 'bioregen.com/verify', but no full company address or accreditation information is provided. The client contact domain differs (biolongevitylabs.com).
Limited Testing Scope
Only identity and purity testing performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic research-grade testing but limits comprehensive quality assurance.
Chromatographic Data Included
LC-MS chromatogram and mass spectrum are provided showing retention time and molecular ion peak at m/z 130.1079, supporting identity confirmation.
Reasonable Timeline
Sample received 12/27/24, analysis conducted 1/3/25 - a 7-day turnaround is reasonable for LC-MS analysis.
Security Features Present but Unverified
Document includes security key 'BIOLABS2010', QR code, and verification URL, but actual verification status cannot be confirmed from the document alone.
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (571 days) — consider whether a retest is warranted for this batch.
