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.
99.3%
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
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
99.3% purity by HPLC-UV/MS is excellent and typical for research-grade peptides
Mass spectral confirmation
Identity confirmed by HPLC-UV-MS with mass spectrum matching authentic standard; CAS number 49557-75-7 provided
Batch/lot number present
Batch/Lot 2fvgmwe clearly stated
Dates are consistent and valid
Sample received 2026-05-05, testing dates 2026-05-08 to 2026-05-15, report issued 2026-05-19; all dates are logical and within acceptable timeframes

Certificate ID 2fvgmwe with verification URL https://finnrick.com/verify
Endotoxin testing performed
Endotoxins <0.5 EU by USP 86 method, passing standard safety threshold
Limited testing panels
Only purity, identity, and endotoxin panels performed; no heavy metals, microbial, sterility, or residual solvent testing reported despite methods being described on page 4
Professional presentation
Multi-page report with chromatogram (page 2), mass spectrum (page 3), and detailed methods summary (page 4); consistent branding and formatting throughout
Supporting analytical data
HPLC chromatogram shows clean single peak; mass spectrum shows expected fragmentation pattern for peptide-copper complex
