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.

    < 0.01 EU/mL

  • 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.

  • Endotoxin testing performed

    Chromogenic LAL assay shows < 0.01 EU/mL, passing the 0.1 EU/mL threshold. Proper controls (positive and negative) included with expected results.

  • Professional lab presentation

    BioRegen branding, contact information, verification instructions, QR code, and validation key (BIOLABS2010) all present. Report ID: BL-ENDO-250804-030.

  • Lot number documented

    LOT #: 38-3-45777 clearly stated for Cortagen product.

  • Test date documented

    Test performed and signed 08/04/2025, which is a valid date (before 2026-07-29).

  • Limited scope - endotoxin only

    This is a single-panel report (endotoxin testing only). No identity, purity, heavy metals, microbial, sterility, or solvent/water content testing included. This is normal for specialized endotoxin testing but means this COA alone does not provide comprehensive quality assurance.

  • Complete reagent documentation

    Kit product number (A39553 Thermo Fisher), endotoxin standard (E.coli O111:B4, OC86T80400), detection range (0.01-1.0 EU/mL), and plate reader specs (Q33326, 405 nm) all documented.
