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).
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% by HPLC-UV-MS with supporting chromatogram and mass spectrum data showing clean single peak at retention time 6.59 minutes
Identity confirmed by mass spectrometry
Mass spectrum shows expected m/z 1586 matching reference standard for Retatrutide (CAS 2381089-83-2)
Branding inconsistency
Document shows dual branding: 'Finnrick Analytics' and 'Krause Analytical LLC' with same address (8127 Mesa Drive Suite B-206, Austin, TX 78759). Header says 'Finnrick.com' and 'Finnrick Analytics Lab #200631' but footer and signature reference 'Krause Analytical LLC' and director 'Mark C. Krause'. This may indicate a parent/subsidiary relationship or rebranding, but creates ambiguity about the actual testing entity.
Methods described but results not shown
Page 3 describes methods for Endotoxins (USP/NF 85) and Metals (USP/NF 233) testing, but no results for these panels appear on the COA. Only identity and purity results are reported.
Batch/lot number present
Batch/Lot j5b9qh4 clearly identified with verification URL provided
Dates are reasonable and sequential
Sample received 1/29/2026, method date 2/8/2026, report issued 2/18/2026 - all dates are sequential and on or before today (2026-07-29)
Professional formatting with supporting data
Document includes vial photos, detailed chromatogram, mass spectrum comparison, methods summary, and proper laboratory disclaimers
