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.

4 of 7 present · 4 passed · 0 failed · 0 reported · 3 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

    Tested · passed

    Lead, arsenic, cadmium, mercury, or similar limits.

    All ND (As, Cd, Pb, Hg)

  • 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.

    ND

  • 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.

  • Excellent chromatographic purity

    HPLC purity >99.9% with clean chromatogram showing single dominant peak at ~7 minutes retention time

  • Mass spectral confirmation

    Mass spectrum shows expected m/z peaks (1579.1, 1184.4) consistent with Retatrutide, ID confirmed by comparison to authentic standard

  • Batch/lot number present

    Batch hqrz3hn clearly documented with 60 mg label claim, 59.4 mg recovered (99.1% of label)

  • Complete date documentation

    Sample received 2026-06-30, testing performed 2026-07-05 to 2026-07-15, report issued 2026-07-20. All dates are logical and sequential.

  • Reputable testing laboratory

    Krause Analytical LLC (Austin, TX) is a known third-party analytical laboratory. Document includes lab director signature (Mark C. Krause) and verification URL.

  • Comprehensive testing panels

    Includes purity, identity, endotoxins, and FDA critical metals (As, Cd, Pb, Hg). All tested parameters passed. Microbial and sterility panels not performed, which is common for research-grade peptides.

  • Professional presentation

    Multi-page report with detailed methods summary, chromatogram, mass spectrum, proper headers/footers, and copyright notice. Consistent with legitimate analytical lab reports.
