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 UPLC and MS
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
Not explicitly stated
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.
Purity percentage not explicitly stated
The COA shows UPLC chromatograms and MS data but does not provide a clear numerical purity percentage value, which is standard for peptide COAs.
Identity confirmation present
UPLC chromatograms and mass spectrometry data are provided, showing analytical methods appropriate for peptide identity confirmation.
Batch/lot number present
Lot Number APR-7332292 is clearly stated.
Dates present and valid
Received Date and Analysis Conducted date both listed as 03/27/2026, which is before the current date of 2026-07-29.
Lab verification uncertain
Horizon Analytical is listed with website horizonanalytical.com. The lab appears professional but independent verification of this specific lab's existence and accreditation was not possible from the document alone.
Limited testing panels
Only identity testing (UPLC/MS) is present. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing is shown. This is not uncommon for basic identity/purity COAs but limits the comprehensiveness.
Professional presentation
Document has professional layout with clear branding, chromatograms, and mass spectrometry data. Includes PubChem CID reference (71587328) for GHK-Cu.
