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
Not on this COA · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.007 ppm, Cd: <0.001 ppm, Hg: <0.001 ppm, Pb: 0.013 ppm
Microbial
Tested · passed
Bioburden / microbial limits testing.
Total Aerobic: <100 cfu/g, Coliforms: <10 cfu/g, E.coli: Absent, Salmonella: Absent, Staph: Absent, Yeast/Molds: <100 cfu/g
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 lacks HPLC or other purity testing, which is essential for peptide/compound verification
No identity confirmation
No MS, NMR, or other identity verification method present; only appearance and flavor tests provided
Lot number present
Lot L1164 clearly documented
No verification URL or contact info
InstaMed lab name present but no website, phone, or address for independent verification
Limited testing scope
Only heavy metals and microbial testing performed; missing critical identity and purity panels for peptide research use
Professional appearance
Document has clear structure, signatures, and standard testing methods (USP 233, USP 2021/2022)
Timing & next steps
Practical follow-ups based on document age and gaps.
