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.
3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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
Tested · passed · core
LAL or chromogenic endotoxin assay.
<0.5 EU/mL
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% with clean chromatogram showing single dominant peak at 5.57 min; this is normal for research-grade peptides
Mass spectrum confirmation
Mass spectrum matches reference standard for Retatrutide with major ions at m/z 1195, 1586 consistent with expected molecular weight
Batch/lot number present
Sample ID uag5ju3, Lab # 132240, Project 135689
Dates consistent
Sample received 2026-01-09, testing dates 2026-01-17 to 2026-01-22, report issued 2026-01-26; all dates are sequential and on or before 2026-07-29
Dual branding inconsistency
Document shows both 'Finnrick Analytics' and 'Krause Analytical LLC' branding throughout; header says Finnrick, footer and signature say Krause Analytical; unclear if this is a legitimate partnership or rebranding
Verification URL domain mismatch
Verification URL is https://finnrick.com/verify but lab name is Krause Analytical LLC; domain ownership and verification system not independently confirmed
Heavy metals method described but not tested
Page 3 describes USP/NF 233 ICP-MS method for metals testing, but no results are reported on the COA; unclear if test was performed
Endotoxin testing performed
Endotoxins <0.5 EU/mL by USP 86 LAL method, within acceptable limits
Professional presentation
Document includes detailed methods summary, chromatogram, mass spectra, signature, and standard COA formatting elements
