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.

    98.72%

  • 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

    98.72% chromatographic purity is excellent and typical for research-grade peptides

  • Mass spectral confirmation

    Identity confirmed by HPLC-UV-MS with reference spectrum comparison shown on page 2

  • Batch/lot number present

    Lot spyfm4w clearly documented with label claim 10 mg, actual 9.86 mg (98.6% of label)

  • Dates consistent

    Sample received 3/3/2026, testing completed 3/11/2026 and 3/20/2026, all dates are reasonable and sequential

  • Lab credentials present

    Krause Analytical LLC with Austin, TX address, laboratory director signature (Mark C. Krause), verification URL provided

  • Limited panel coverage

    Only identity, purity, and endotoxin testing performed. No heavy metals, microbial, sterility, or residual solvent testing documented

  • Professional presentation

    Multi-page report with chromatogram, mass spectra, detailed methods summary (USP/NF references), and proper watermarking
