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.
2 of 7 present · 0 passed · 0 failed · 2 reported · 5 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 · result on file · core
Compound identity confirmed (e.g. HPLC, mass spec).
Confirmed by MS (m/z 1653.21, charge state +2)
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
Not explicitly quantified on this page
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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.
Identity confirmation present
UPLC chromatogram and MS spectrum provided. MS shows expected m/z for TB-500 (1653.21 for +2 charge state, consistent with molecular weight ~3306 Da). PubChem CID 16132341 referenced.
Purity percentage not stated
UPLC chromatogram shows a dominant peak, but no explicit purity percentage is printed on this page. Cannot confirm quantitative purity claim.
Lot number present
Lot Number: APR-7332292
Dates present and valid
Received Date: 03/27/2026, Analysis Conducted: 03/27/2026. Both dates are on or before 2026-07-29 (today) and are therefore valid.
Lab verification not independently confirmed
Testing lab is 'Horizon Analytical' with URL horizonanalytical.com. Client is 'American peptide research' (Americanpeptideresearch.com). Cannot independently verify lab accreditation or existence from image alone.
Limited testing scope
Only identity (UPLC/MS) testing is shown. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing panels are present. This is common for identity-only COAs but limits safety assurance.
Professional presentation
Document has professional layout with lab logo, clear chromatograms, and MS spectrum. Formatting is consistent with analytical lab reports.
