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 · 1 passed · 1 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 · failed · core
Compound identity confirmed (e.g. HPLC, mass spec).
Not Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
98.93%
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.
Identity Test Failed
HPLC retention time matching (HPLC-RTM) could not confirm the sample as MOTS-C. The chromatographic retention time did not match the expected reference standard. This is a critical failure indicating the compound may not be what is labeled.
High Purity Achieved
Peptide purity of 98.93% by HPLC exceeds the ≥95.0% specification and is within normal range for research-grade peptides.
Batch Information Complete
Lot number 10232 clearly documented with labeled content of 40mg and net peptide content of 41.07mg.
Timeline Appropriate
Sample received 2026-06-21, analyzed and issued 2026-07-10. Reasonable turnaround time of 19 days.
Accredited Laboratory
ILS Laboratories claims ISO/IEC 17025 accreditation with complete contact information, verification URL, and QR code for authenticity checking.
Limited Testing Scope
Only identity and purity panels performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic peptide analysis but limits comprehensive quality assessment.
Professional Presentation
Document includes HPLC chromatogram, clear pass/fail indicators, methodology notes, lab director signature, and verification mechanisms. Formatting consistent with professional laboratory standards.
