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.
99.64%
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.
ND (Not Detected)
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
99.64% purity by HPLC-UV/MS is excellent and typical for research-grade peptides
Identity confirmed by mass spectrometry
Mass spectrum matches reference standard for GHK-Cu (CAS 49557-75-7); chromatogram and MS data provided on page 2
Batch/lot number present
Lab # 130412, Test Certificate ID yq5kpse clearly stated
Dates are logical and recent
Sample received 2025-11-19, testing 2025-11-23, report issued 2025-11-25 — all sequential and reasonable
Testing lab identified
Krause Analytical LLC, 8127 Mesa Drive Suite B-206, Austin, TX 78759; signed by Mark C. Krause, Laboratory Director
Verification URL provided
https://finnrick.com/verify listed for independent verification
Endotoxin testing performed
Endotoxins not detected (ND) at LOQ 1 EU/mL by USP 86 method
Heavy metals testing not performed
Method summary describes USP/NF 233 ICP-MS for metals, but no results reported on COA
Microbial and sterility testing absent
No microbial count or sterility panel results provided
Professional formatting with supporting data
Includes chromatogram, mass spectrum comparison, detailed methods summary, and watermarked pages
Potency exceeds label claim
112 mg measured vs 100 mg label claim (112.1% of label) — acceptable overfill for lyophilized peptides
