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.
4 of 7 present · 3 passed · 0 failed · 1 reported · 3 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
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: ND, Cd: ND, Pb: 0.54 µg, Hg: ND
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.
0.67 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% is excellent and typical for high-quality research peptides. Chromatogram shows single dominant peak at 6.58 min with minimal impurities.
Mass spectral confirmation
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 ntm93fs clearly stated with label claim 30 mg, actual 27.7 mg (92.4% of label).
Testing dates documented
Sample received 3/18/2026, peptide analysis 3/22/2026, endotoxin 3/26/2026, metals 4/7/2026. All dates are sequential and reasonable.
Established testing laboratory
Krause Analytical LLC is a known contract testing lab in Austin, TX. Document includes lab director signature (Mark C. Krause), address, and verification URL.
Comprehensive testing suite
Includes identity, purity, endotoxin, and FDA critical metals (As, Cd, Pb, Hg). Methods summary provided on page 3 with USP references.
Missing microbial and sterility panels
No microbial contamination testing (total aerobic count, yeast/mold) or sterility testing documented. Endotoxin testing alone does not cover full microbial safety.
Professional presentation
Multi-page report with chromatogram, mass spectra, methods summary, and watermarking. Consistent branding between Finnrick (vendor) and Krause Analytical (testing lab).
