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.
1.9 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.
Excellent chromatographic purity
HPLC purity >99.9% with clean chromatogram showing single dominant peak at 6.59 min. This is normal for high-quality research peptides.
Identity confirmed by mass spectrometry
Mass spectrum matches reference standard for Retatrutide (CAS 2381089-83-2). Both sample and reference spectra provided on page 2.
Batch/lot number present
Batch/Lot 3ujjag4 clearly stated. Lab # 202940, Project 145128.
Dates are consistent and valid
Sample received 3/16/2026, testing performed 3/22/2026 and 3/26/2026. All dates are on or before 2026-07-29 (today) and logically sequenced.
Testing lab identified with verification URL
Krause Analytical LLC, 8127 Mesa Drive Suite B-206, Austin, TX 78759. Verification URL provided: https://finnrick.com/verify. Certificate ID: 3ujjag4. Signed by Mark C. Krause, Laboratory Director.
Limited testing panels
Only purity, identity, and endotoxin panels performed. Heavy metals, microbial, sterility, and residual solvent/water panels not tested. Methods summary describes metals testing (USP/NF 233) but no results provided.
Endotoxin result without pass/fail criteria
Endotoxin level reported as 1.9 EU but no acceptance limit or pass/fail statement provided.
Professional formatting with supporting data
Document includes chromatogram, mass spectra comparison, detailed methods summary, and proper USP/NF method references. Watermarked 'FINNRICK' throughout.
