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.
4 of 7 present · 2 passed · 0 failed · 2 reported · 3 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 · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
>99.9%
Heavy metals
Tested · result on file
Lead, arsenic, cadmium, mercury, or similar limits.
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 · result on file · core
LAL or chromogenic endotoxin assay.
0.98 EU/vial
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 chromatographic purity
HPLC purity >99.9% is normal for research-grade peptides and supported by clean chromatogram with single dominant peak at 0.58 min.
Mass spectrum confirmation
Mass spectrum shows expected m/z 342 matching GHK-Cu reference standard with good correlation.
Unusual batch/lot format
Batch number 'bnkauur' appears non-standard (lowercase, no typical numeric/date structure). Also matches the Test Certificate ID exactly, which is atypical.
Dual branding inconsistency
Document shows both 'Finnrick Analytics' and 'Krause Analytical LLC' branding. Header says 'Finnrick Analytics' but footer, signature, and methods reference 'Krause Analytical LLC'. This dual identity is unusual and not clearly explained.
Heavy metals method listed but no results
Page 3 describes USP/NF 233 ICP-MS method for metals testing, but no heavy metals results appear on the COA summary page. Unclear if test was performed.
Endotoxin testing present
Endotoxin result of 0.98 EU/vial is within typical acceptable range for research peptides.
Professional presentation
Document includes detailed methods summary, chromatogram, mass spectra, signature, and verification URL. Layout is professional and consistent with legitimate analytical lab reports.
