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 · 2 passed · 0 failed · 0 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 · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
Expected: 402.10 g, Measured: 402.11 g
Purity
Tested · passed · core
Reported purity percentage for the analyte.
98.9%
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.

98.9% purity by HPLC-UV with clear chromatogram showing dominant peak at 7.23 min (98.9% area)
Mass confirmed
Measured mass (402.11 g) matches expected mass (402.10 g) within acceptable tolerance
Lab verification limited
MZ Biolabs (Tucson, AZ) contact information provided but independent verification of lab accreditation not readily available from document

Only identity and purity panels performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing documented
Professional presentation
Document includes chromatogram, peak list, PubChem reference, analyst signature, and client information
External reference provided
PubChem CID 71587328 provided for independent compound verification
Timing & next steps
Practical follow-ups based on document age and gaps.
