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

    HPLC purity >99.9% is excellent and typical for research-grade peptides. Supported by clean chromatogram showing single dominant peak at 6.59 min.

  • Identity confirmed by mass spectrometry

    Mass spectral match confirmed via HPLC-UV-MS with reference spectrum shown on page 2. CAS number 2381089-83-2 provided for Retatrutide.

  • Batch/lot number present

    Batch/Lot 3me4bsm clearly stated. Lab number 203097, Project 145133 also documented.

  • Dates are consistent and valid

    Sample received 3/18/2026, analysis/report issued 3/22/2026. Both dates are before today (2026-07-29) and show reasonable turnaround time.

  • Testing lab identified with contact information

    Krause Analytical LLC, 8127 Mesa Drive Suite B-206, Austin, TX 78759. Laboratory Director Mark C. Krause signature present. Verification URL provided: https://finnrick.com/verify

  • Limited testing panels

    Only identity and purity panels show results. Methods summary describes endotoxin (LAL) and heavy metals (ICP-MS) procedures, but no results are reported for these or other safety panels (microbial, sterility, residual solvents). This is common for basic peptide analysis but limits comprehensive quality assessment.

  • Professional presentation with supporting data

    Document includes chromatogram, mass spectrum comparison, detailed methods summary (USP/NF references), and proper legal disclaimers. Watermarked pages indicate authenticity measures.

  • Label claim vs actual content documented

    Label claim 30 mg, actual content 25.0 mg (83.2% of label claim). This variance is disclosed transparently and is within acceptable range for lyophilized peptides.
