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).

    Selank, Semax

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.9%

  • Heavy metals

    Tested · passed

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

    <0.01 ppm

  • 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

    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 purity confirmed

    99.9% purity by RP-HPLC is excellent and typical for research-grade peptides

  • Dual identity confirmation

    Both MALDI-MS identity and HPLC chromatogram with mass spectrum provided, showing expected molecular ions for Selank and Semax

  • Core safety panels present

    Identity, purity, heavy metals, and endotoxin testing all performed and passed

  • Clear batch identification

    Lot number SEMSEL5-0616 clearly stated

  • Recent testing with appropriate timeline

    Sample received 2026-06-19, COA issued 2026-06-25 (6-day turnaround is reasonable)

  • Professional presentation

    Bioviridian COA with verification URL, QR code, and signature from Principal Chemist Shane Straight, M.S.

  • Complete documentation

    Includes chromatogram with retention time (1.759, 8.465 min), mass spectrum, product image, and all standard COA elements

  • Microbial and sterility testing not performed

    No microbial limit or sterility testing reported; acceptable for research use but users should be aware
