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.
99.422%; 99.493%; 99.467%
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 replicate measurements averaging ~99.46% purity. This is normal for research-grade peptides and not inherently suspicious.
No identity confirmation method stated
The report does not specify the analytical method used (e.g., HPLC, LC-MS) or provide identity confirmation data such as mass spectrometry results or retention time.
Limited testing scope
Only purity testing is documented. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is present. This is common for basic peptide analysis but limits comprehensive quality assurance.
Known testing laboratory
Janoshik is a recognized third-party analytical laboratory in the peptide/research compound space.
Batch number present
Batch TIR60N042225 is clearly stated.
Dates are consistent and valid
Testing ordered 25 APR 2025, sample received 29 APR 2025, analysis conducted 30 APR 2025. All dates are sequential and on or before 2026-07-29.
Minimal detail and formatting
The report is brief and lacks detailed methodology, chromatograms, or pass/fail criteria. While not necessarily indicative of fraud, it provides limited transparency for independent verification.
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (455 days) — consider whether a retest is warranted for this batch.
