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.

5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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).

    Semaglutide

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.9%

  • Heavy metals

    Tested · passed

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

    <0.01ppm

  • 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.

    <0.05 EU/mL

  • Sterility

    Tested · passed

    Sterility testing where applicable.

    Not Detected

  • 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.

  • Future dates

    Sample received June 1, 2026 and COA issued June 17, 2026 - both dates are in the future, which is impossible for a legitimate current document

  • High purity reported

    99.9% purity via RP-HPLC at 214nm with clear chromatogram showing single peak at 10.818 min retention time

  • Identity confirmed

    MALDI-MS confirms semaglutide with mass spectrum showing [M+H]+ at 4113.36, matching expected MW of 4113.6 g/mol

  • Comprehensive testing

    Includes identity, purity, content quantitation (20.93 mg), sterility, heavy metals, and endotoxin testing - all conforming

  • Lab verification unclear

    Bioviridian lab with verification URL provided, but future dates raise questions about document authenticity

  • Professional presentation

    Well-formatted COA with clear chromatograms, mass spectrum, product photo, QR code, and signature from Shane Straight, M.S., Principal Chemist

  • Batch information present

    Lot number SEMA20-0528 clearly stated with vendor American Peptides
