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 · 4 passed · 0 failed · 0 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.
99.8%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.60 µg, Cd: ND, Pb: 0.91 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 · 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
99.8% 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
Batch/lot number present
Batch ga3j9vc clearly documented with verification URL provided
Established testing laboratory
Krause Analytical LLC is a known third-party testing lab in Austin, TX with proper credentials and signature
Comprehensive testing suite
Includes purity, identity, endotoxin, and heavy metals panels with detailed methods summary
Professional presentation
Complete with chromatogram, mass spectrum, detailed methods, watermarks, and proper footer information
Potency exceeds label claim
60.6 mg found vs 50 mg label claim (121.3% of label) indicates good manufacturing control
Missing microbial and sterility panels
No total aerobic count, yeast/mold, or sterility testing documented; only endotoxin testing present
