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).

    ID Confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.18%

  • 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.

    <0.5 EU

  • 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 HPLC purity confirmed

    99.18% chromatographic purity by HPLC-UV/MS with supporting chromatogram showing clean major peak at 0.81 min

  • Mass spectral identity confirmed

    Mass spectrum matches reference standard for glutathione; reference spectrum provided on page 2

  • Batch/lot number present

    Lot g8k5ahp clearly marked on vial photo and throughout document

  • Dates are consistent and logical

    Sample received 2/26/2026, endotoxin test 2/28/2026, peptide analysis and report issued 3/3/2026 - all sequential and reasonable

  • Testing lab identified with verification URL

    Krause Analytical LLC, Austin TX, with verification URL https://finnrick.com/verify and certificate ID g8k5ahp

  • Limited panel coverage

    Only purity, identity, and endotoxin panels performed; heavy metals, microbial, sterility, and residual solvent/water tests not conducted despite methods being described

  • Professional formatting with supporting data

    Includes chromatogram, mass spectrum comparison, methods summary, lab director signature, and product photos

  • Potency exceeds label claim

    1,280 mg found vs 1,200 mg label claim (107.0% of label) - within acceptable range for lyophilized peptides
