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.
1 of 7 present · 0 passed · 0 failed · 1 reported · 6 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).
MS2 ES+ 5.2865, TIC 1.4169, ES+ TIC 2.1327
Purity
Not on this COA · core
Reported purity percentage for the analyte.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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.
No purity value reported
The COA shows UPLC and MS data but does not state a quantitative purity percentage, which is essential for research peptide quality assessment.
Identity testing present
UPLC chromatograms and mass spectrometry data are provided showing molecular ion peaks consistent with TB-500. Pubchem CID 16132341 is referenced.
Batch number present
Lot Number APR-7308120 is clearly stated.
Lab verification unclear
Horizon Analytical is named with contact email and website, but independent verification of this lab's accreditation or reputation was not possible from the document alone.
Limited testing scope
Only identity testing (UPLC/MS) is present. No purity quantification, heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is shown.
Professional presentation
Document has professional layout with clear branding, chromatograms, and mass spectra. Client name 'American peptide research' and identity 'Americanpeptideresearch.com' are stated.
