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).

    ID Confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    >99.9%

  • 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.

  • High chromatographic purity confirmed

    HPLC-UV/MS shows >99.9% purity with clean chromatogram showing single dominant peak at 6.85 min

  • Mass spectral identity confirmed

    Mass spectrum shows expected m/z peaks for Tirzepatide (1613.7, 1216.0, 1210.6) consistent with multiply-charged species; ID confirmed vs authentic standard

  • Batch/lot number present

    Lot bbrxqw4 clearly stated; label claim 5 mg, actual 5.03 mg (100.6% of label)

  • Dates are consistent and valid

    Sample received 2026-04-10, tested 2026-04-17, report issued 2026-04-28; all dates are sequential and on or before 2026-07-29

  • Established laboratory with verification URL

    Krause Analytical LLC, Austin TX; verification URL provided (https://finnrick.com/verify); signed by Mark C. Krause, Laboratory Director

  • Limited testing panels performed

    Only identity and purity panels performed; endotoxin and heavy metals methods described on page 4 but no results shown; microbial, sterility, and residual solvent testing not performed

  • Professional formatting with supporting data

    Multi-page report with chromatogram (page 2), mass spectrum (page 3), and methods summary (page 4); consistent branding and layout
