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).
Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.91%
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.
ND (Not Detected)
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
99.91% purity by HPLC-UV/MS is excellent and normal for research-grade peptides
Identity confirmed
Tirzepatide identity confirmed by HPLC-UV-MS with mass spectrum matching reference standard (m/z 1205 base peak consistent with tirzepatide)
Dual branding inconsistency
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'. This dual branding pattern could indicate a reseller/white-label arrangement or raise questions about document authenticity
Lab verification needed
Verification URL provided (https://finnrick.com/verify) but relationship between Finnrick and Krause Analytical is unclear from document alone
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
Endotoxin testing passed
Endotoxins not detected (ND) at LOQ of 1 EU/mL by USP 86 method
Batch/lot number present
Lab # 130414 clearly stated
Dates are valid and sequential
Sample received 2025-11-19, testing 2025-11-23/11-25, report issued 2025-11-25. All dates are sequential and on or before 2026-07-29
Professional presentation
Document includes chromatogram, mass spectra, detailed methods summary, and proper USP method references
