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).

    GHK-Cu

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.766%

  • Heavy metals

    Tested · passed

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

    All Negative (As, Cd, Pb, Hg)

  • Microbial

    Tested · passed

    Bioburden / microbial limits testing.

    No Growth

  • Endotoxin

    Tested · passed · core

    LAL or chromogenic endotoxin assay.

    Pass

  • 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

    Batch average purity of 99.766% with consistent vial-to-vial results (99.711% and 99.821%), supported by clean chromatogram showing single major peak

  • Identity confirmed by LC-MS

    GHK-Cu identity confirmed via LC-MS, matching expected molecular formula C14H24N6O4Cu

  • Comprehensive safety screening

    Includes heavy metals (As, Cd, Pb, Hg all negative), endotoxin safety screen (pass), fentanyl presence analysis (not detected), and microbial sterility screen (no growth)

  • Batch conformity documented

    Two-vial batch conformity testing shows consistent purity and net content across samples

  • Recent certification date

    Certified 07/15/2026, which is within normal timeframe (14 days before current date 2026-07-29)

  • Lab verification not independently confirmed

    Kovera Labs is named as testing facility with QR code and access code provided, but no URL or independent verification method visible on document. Cannot confirm lab legitimacy from this image alone

  • Professional presentation

    Document shows professional formatting with clear sections, proper chromatogram with method details (RP-HPLC, C18 column, DAD @ 214 nm), product photo, and signature

  • Missing residual solvent/water content

    No residual solvent or water content analysis present, though this is common for many peptide COAs and not necessarily a red flag
