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).
TB-500 (TB4) identified along with mannitol and degradation products
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 quantification
This report is labeled as a contamination screening test only. No HPLC purity percentage is provided, which is essential for a complete COA for research peptides.
Degradation products detected
LCMS analysis identified degradation products alongside TB-500, which may indicate storage or handling issues, though no quantification of degradation is provided.
Limited testing scope
Only LCMS contamination screening was performed. No purity quantification, heavy metals, microbial, endotoxin, sterility, or residual solvent testing is included.
Batch number present
Batch Test-CY3 is clearly identified.
Known testing lab
Janoshik is a recognized third-party testing laboratory for research compounds. Verification URL and unique key (AWP2R8UR5S57) are provided.
Professional presentation
Report includes chromatogram and mass spectra data from Shimadzu LabSolutions, consistent with legitimate analytical output.
