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 · 0 failed · 1 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 · result on file · core
Compound identity confirmed (e.g. HPLC, mass spec).
MOTS-C
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
Tested · passed · core
LAL or chromogenic endotoxin assay.
PASS
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.
Purity data missing
No HPLC or other purity analysis is reported. This is a critical omission for peptide quality verification.
Identity method unclear
The identity field shows 'MOTS-C' but does not specify the analytical method used (e.g., mass spectrometry, amino acid analysis). The method is essential for verification.
Batch number listed as NA
The batch number field shows 'NA', which is unusual for a legitimate COA. Batch traceability is a fundamental quality control requirement.
Multiple critical panels missing
Missing purity analysis, heavy metals testing, microbial testing, sterility testing, and residual solvent/water content. Only endotoxin testing is present.
Minimal testing scope
This COA only reports endotoxin testing (LAL) and a basic identity field. The limited scope raises questions about comprehensive quality control.
Lab contact information provided
Lab name, contact email, website, and signatory are present. MDx BioAnalytical Laboratory, Inc. is identified with verification URL mdxbiolabs.com.
Dates are reasonable
Received date 2025-10-30 and reported date 2025-11-03 are both before the current date (2026-07-28) and show a reasonable 4-day turnaround.
