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 · 2 passed · 0 failed · 1 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 · result on file · core
LAL or chromogenic endotoxin assay.
2.5 EU
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
>99.9% purity by HPLC-UV/MS with clean chromatogram showing single dominant peak at ~7 minutes retention time
Mass spectral confirmation
Mass spectrum shows expected charge states for Tirzepatide (m/z 1613.4, 1216.0, etc.) with ID confirmed by comparison to authentic standard
Batch/lot number present
Batch 2jx3cqq clearly documented with Lab # 206580 and Project 145283
Dates within normal range
Sample received 2026-06-04, testing performed 2026-06-06 to 2026-06-11, report issued 2026-06-15 - all dates are consistent and on or before 2026-07-29
Branding inconsistency
Document shows dual branding: header/footer say 'Finnrick Analytics' and 'Finnrick.com' but signature block, methods, and address reference 'Krause Analytical LLC' at 8127 Mesa Drive Suite B-206 Austin, TX 78759. This suggests Finnrick may be a reseller/distributor rather than the actual testing lab, or there is a partnership arrangement not clearly explained on the COA
Verification URL provided but not independently confirmed
Document provides verification URL https://finnrick.com/verify with certificate ID 2jx3cqq, but independent verification of this URL's legitimacy cannot be performed from the document alone
Limited testing panels
Only purity, identity, and endotoxin testing performed. No heavy metals results reported despite method being described on page 4, and no microbial, sterility, or residual solvent testing. This is not uncommon for research-grade peptides but limits quality assurance
Professional presentation
Document includes detailed methods summary, chromatogram, mass spectrum, proper USP method references, and laboratory director signature
