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).
DSIP confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.54%
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 purity confirmed
UPLC analysis shows 99.54% purity with clean chromatogram showing single major peak
Identity confirmed by MS
Mass spectrometry data shows expected molecular ion peak at 847.46 m/z with characteristic fragmentation pattern consistent with DSIP
Clear batch identification
Lot number APR-1049032-P clearly stated with CAS number 62568-57-4 and molecular formula C35H48N10O15
Appropriate timeline
Sample received 2026-02-21, analysis conducted 2026-03-06 - reasonable 13-day turnaround
Professional presentation
Horizon Analytical branding, signed by Aleksey Yevtodiyenko PhD (Research and Formulation Chemist), includes verification QR code and contact information
Limited testing scope
COA only includes identity and purity testing. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing performed. This is common for basic research-grade peptide analysis but limits comprehensive quality assessment
Professional documentation
Well-formatted certificate with clear data presentation, chromatograms, mass spectrum, and appropriate disclaimers for research use
