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 · 3 passed · 0 failed · 0 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 · passed · core
LAL or chromogenic endotoxin assay.
<0.5 EU/vial
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
HPLC purity >99.9% is normal for research-grade peptides and supported by clean chromatogram with single dominant peak at 6.41 min
Mass spectrum confirmation
Mass spectrum shows expected m/z peaks (1195, 1586) matching reference standard for Retatrutide, confirming identity
Potency within specification
Measured 5.52 mg vs 5 mg label claim = 110.3% of label, within typical acceptable range for lyophilized peptides
Batch/lot number present
Batch/Lot ckdwpqc clearly stated and visible on vial photos
Dates are logical and current
Sample received 2026-01-16, testing 2026-01-26 to 2026-02-01, report issued 2026-02-04 — all dates are sequential and on or before 2026-07-29
Established testing laboratory
Krause Analytical LLC is a known third-party analytical lab in Austin, TX with verifiable address and director signature
Verification URL provided
Certificate includes verification URL https://finnrick.com/verify with certificate ID ckdwpqc for independent validation
Limited testing panels
Only purity, identity, and endotoxin testing performed. No heavy metals, microbial, sterility, or residual solvent testing shown, though methods summary describes metals testing capability
Professional presentation
Multi-page COA with detailed methods summary, chromatogram, mass spectra, vial photos, and proper USP method references
Duplicate endotoxin entries
Endotoxin test appears twice with identical results (<0.5 EU/vial, USP 86, 1/26/2026) — likely formatting artifact but unusual
