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.

    99.687%

  • Heavy metals

    Tested · passed

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

    As, Cd, Pb, Hg all Negative

  • 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.

    PASS (≤0.5 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 confirmed

    Batch average purity of 99.687% with consistent individual vial results (99.568-99.788%) meets >98% specification

  • Identity confirmed by LC-MS

    Semaglutide identity confirmed via LC-MS with correct molecular formula C187H291N45O59 and CAS 1997361-85-9

  • Comprehensive testing panel

    Includes purity, identity, heavy metals, endotoxin, fentanyl screening, and rapid sterility testing

  • Batch conformity data provided

    Five individual vials tested with detailed purity and net content measurements showing good batch consistency

  • Verification system present

    Report includes verification URL (koveralabs.com/verify) with access code TFXHQIP and QR code for authentication

  • Sample date not specified

    COA shows certification date (06/10/2026) but does not explicitly state when the sample was received or initially tested

  • Professional presentation

    Well-formatted document with clear sections, chromatogram, product photo, and lab director signature

  • Additional testing included

    Fentanyl presence analysis included (Not Detected) - unusual but increasingly common safety measure for research peptides
