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.

6 of 7 present · 6 passed · 0 failed · 0 reported · 1 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).

    PT-141

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.742%

  • Heavy metals

    Tested · passed

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

    As <0.15, Cd <0.05, Pb <0.5, Hg <0.3

  • Microbial

    Tested · passed

    Bioburden / microbial limits testing.

    No Growth

  • Endotoxin

    Tested · passed · core

    LAL or chromogenic endotoxin assay.

    Pass

  • Sterility

    Tested · passed

    Sterility testing where applicable.

    No microbial growth 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.

  • High purity confirmed

    Batch average purity of 99.742% with consistent individual vial measurements (99.571-99.869%), supported by chromatogram showing single dominant peak

  • Identity confirmed by LC-MS

  • Comprehensive testing panel

    Six major testing categories present: purity, identity, heavy metals, endotoxin, fentanyl screening, and dual microbial/sterility tests. Only residual solvents/water content not explicitly reported

  • Batch conformity documented

    Five individual vials tested with detailed purity and net content measurements, demonstrating batch consistency

  • Professional lab presentation

    Kovera Labs report with verification URL, access code (DO7OP9D), report number (KVR-2026-28597D), and lab director signature
