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).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
>99.95%
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 chromatographic purity confirmed
HPLC-UV/MS shows >99.95% purity with clean chromatogram showing single dominant peak at 6.52 minutes
Identity confirmed by mass spectrometry
Mass spectrum matches reference spectrum for Retatrutide with characteristic m/z peaks at 1185, 1579
Batch/lot number present
Lab # 129620, Test Certificate ID: 5yyx57h
Dates are consistent and reasonable
Sample received 10/14/2025, testing performed 10/22/2025, report issued 10/23/2025 - all dates are sequential and within normal turnaround time
Testing lab identified with contact information
Krause Analytical LLC, 8127 Mesa Drive Suite B-206, Austin, TX 78759. Signed by Mark C. Krause, Laboratory Director
Dual branding requires verification
Document shows both Finnrick Analytics/Finnrick.com branding and Krause Analytical LLC. Footer indicates 'Finnrick Testing Certificate © 2026 Finnrick Analytics LLC and its suppliers' suggesting Finnrick may be a reseller/distributor using Krause as contract lab
Limited testing scope
Only identity and purity panels performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic research-grade peptide testing but limits comprehensive quality assessment
Professional presentation with supporting data
Includes sample photos, full chromatogram, and comparative mass spectra. Watermarked throughout. Professional layout consistent with analytical lab reports
