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.
>99.9%
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
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 >99.9% purity with clean chromatogram showing single dominant peak at 6.71 min
Mass spectral identity confirmed
MS data shows expected m/z peaks (1586.2, 1195.4, etc.) consistent with Retatrutide; ID confirmed by comparison to authentic standard
Batch/lot number present
Batch 55kcj52 clearly stated; matches test certificate ID
Dates are consistent and valid
Sample received 2026-04-10, tested 2026-04-16, report issued 2026-04-28 - logical sequence, all dates ≤ 2026-07-29
Testing lab identified
Krause Analytical LLC, Austin TX; signed by Mark C. Krause, Laboratory Director
Verification URL provided
https://finnrick.com/verify listed for certificate verification
Limited testing panels
Only identity and purity panels performed; endotoxin and metals methods described on page 4 but no results shown; no microbial, sterility, or residual solvent testing
Dual branding present
Document shows both 'Finnrick Analytics' and 'Krause Analytical' branding; appears Finnrick may be a reseller/distributor of Krause services
Potency vs label claim documented
9.26 mg recovered vs 10 mg label claim = 92.6% of label, within acceptable range for lyophilized peptides
