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.
