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 · 2 passed · 0 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 · 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
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 HPLC purity confirmed
Chromatographic purity >99.9% with clean chromatogram showing single dominant peak at 6.43 min. This is normal for research-grade peptides.
Mass spectrum match confirmed
Mass spectrum shows expected m/z 1195 matching reference standard for Retatrutide. CAS number 2381089-83-2 provided.
Batch/lot number present
Batch/Lot af8jwd3 clearly stated with label claim 10 mg, actual 9.97 mg (99.7% of label).
Dates are reasonable and consistent
Sample received 2026-01-23, method date 2026-02-03, report issued 2026-02-11. All dates are sequential and on or before 2026-07-29.
Dual branding creates confusion
Document shows both 'Finnrick Analytics' and 'Krause Analytical LLC' branding. Header says 'Finnrick.com' and 'Finnrick Analytics' but footer and signature reference 'Krause Analytical LLC' with director Mark C. Krause. This dual identity is unusual but could represent a partnership or rebranding.
Methods described but results not shown
Page 3 describes methods for Endotoxins (USP/NF 85) and Metals (USP/NF 233) but no actual test results are provided on the COA. Only purity/potency/identity results are shown.
Large watermark obscures content
Heavy 'FINNRICK' watermark across all pages makes some text difficult to read, though key data fields remain legible.
Verification URL provided
Certificate ID af8jwd3 with verification URL https://finnrick.com/verify allows independent verification.
