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 · 0 passed · 0 failed · 1 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
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
Tested · result on file · core
Reported purity percentage for the analyte.
99.217%; 99.465%; 99.437%
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.
High purity reported
Three purity measurements reported (99.217%, 99.465%, 99.437%) with average ~99.4%, which is normal for research-grade peptides
No identity confirmation
No mass spectrometry, amino acid analysis, or other identity verification method reported. Only purity testing appears to have been conducted.
Limited testing scope
Only purity testing performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing reported. This is common for basic peptide testing but limits comprehensive quality assurance.
Batch number present
Batch RET24N032625 clearly identified
Dates present and logical
Testing ordered 29 MAR 2025, sample received 02 APR 2025, analysis conducted 03 APR 2025. All dates are sequential and reasonable.
Known testing laboratory
Janoshik is a recognized peptide testing laboratory. Verification URL and unique key (X8KH5T29DIDV) provided for authentication.
Professional presentation
Document has consistent branding, clear layout, QR code, signature, and verification information
Timing & next steps
Practical follow-ups based on document age and gaps.
