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).

    Thymosin alpha-1

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.952%

  • Heavy metals

    Tested · passed

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

    Pb <0.4, Cd <0.07, Hg <0.4, As <0.17

  • 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.

    < 0.02 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

    99.952% purity by RP-HPLC with batch conformity testing showing consistent results across two vials (99.968%, 99.951%)

  • Identity confirmed

    LC-MS confirmation of Thymosin alpha-1 with correct molecular formula C129H215N33O55 and CAS 1337515-90-8

  • Batch information complete

    Batch TA202602 with detailed vial-level conformity data and physical descriptors (orange cap, silver crimp)

  • Lab identification present

    Kovera Labs with verification URL koveralabs.com/verify, report number KVR-2026-9E35D5, access code W2LKWDU, and lab director signature

  • Core panels present

    Purity, identity, endotoxin, and heavy metals testing completed. Microbial, sterility, and residual solvent panels not included but this is common for research-grade peptides

  • Missing sterility/microbial testing

    No microbial or sterility testing reported. This may be acceptable for research use but would be required for clinical applications

  • Professional presentation

    Well-formatted document with chromatogram, QR code, batch conformity data, and product photograph. Includes method details (RP-HPLC, C18 column, DAD @ 214 nm)
