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).

    Semax

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.921%

  • Heavy metals

    Tested · passed

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

    All negative (Pb, Cd, As, Hg)

  • Microbial

    Tested · passed

    Bioburden / microbial limits testing.

    No Growth

  • Endotoxin

    Tested · passed · core

    LAL or chromogenic endotoxin assay.

    < 0.10 EU/mL

  • Sterility

    Tested · passed

    Sterility testing where applicable.

    No Growth

  • 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 achieved

    Batch average purity of 99.921% with tight vial-to-vial consistency (99.914-99.927%) is excellent and typical for research-grade peptides.

  • Identity confirmed

    LC-MS confirmation matches expected compound (Semax). Molecular formula C37H51N9O10S and CAS 80714-61-0 are consistent with Semax.

  • Comprehensive testing panel

    Includes identity, purity, heavy metals, endotoxin, and microbial sterility. All panels show passing results.

  • Batch conformity documented

    Three vials tested individually with results tabulated. Net content averages 19.86 mg (within spec of 20mg ± 10%).

  • Lab identification present

    Kovera Labs identified with verification URL (koveralabs.com/verify), report number KVR-2026-CAAD42, and access code N371N8T.

  • Sample date not explicitly stated

    Analysis date is 03/31/2026, but no separate sample collection/receipt date is provided.

  • Professional presentation

    Document includes chromatogram, product photo, QR code, and signature from Lab Director (David Corbin). Layout is clean and organized.

  • Residual solvent/water content not tested

    No Karl Fischer or residual solvent analysis reported. This is common but not universal for peptide COAs.
