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 · 1 passed · 0 failed · 0 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 · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
GHK-Cu, KPV, TB-500, BPC-157 identified by HPLC
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 analysis
COA reports only assay (quantity) measurements for four peptides but provides no purity percentage or chromatographic purity data. This is a fundamental omission for peptide quality control.
Identity confirmation unclear
HPLC methods listed (TESTMET-CH-310, TESTMET-CH-321) appear to be assay methods. No explicit identity confirmation method (e.g., mass spectrometry, amino acid analysis) is documented.
Missing critical safety panels
No heavy metals, microbial contamination, endotoxin, sterility, or residual solvent/water testing reported. These are standard for research peptides intended for any biological use.
No sample/test dates
COA shows issue date (2026-07-17) but no sample collection date or testing completion date, making it impossible to assess sample age or testing timeline.
Lab verification not possible
Qalitex Inc. claims ISO/IEC 17025:2017 accreditation (AGS-US050824-1) but no verification URL or QR code link provided. Independent verification of accreditation status cannot be performed from this document.
Unusual assay reporting
Results show mass quantities (e.g., '56 mg' vs specification '50 mg') rather than percentage purity or concentration. This is atypical for peptide COAs and suggests quantity verification rather than quality analysis.
Batch identification present
Batch number N260710-001 and lot number SP26-KLV80 clearly documented.
