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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.2%
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
HPLC purity of 99.2% is excellent and typical for research-grade peptides. Chromatogram shows clean single peak consistent with stated purity.
Identity confirmed by MS
Mass spectrometry data provided shows [M+H]+ peak at 849.98 m/z, consistent with DSIP molecular weight. HPLC-UV-MS method is appropriate for peptide identity confirmation.
Batch information present
Lot number DSIP10202025-J clearly stated. Accession number 2510220149 matches COA number.
Dates are valid
Received date 10/22/2025 and reported date 10/25/2025 are both before today (2026-07-28) and show reasonable 3-day turnaround time.
Lab verification not independently confirmed
Freedom Diagnostics is identified with contact information (FreedomDiagnosticsTestInc.com, [email protected]). However, no independent verification URL or third-party validation is provided. Lab claims USA operation.
Limited testing scope
Only identity and purity testing performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic peptide COAs but limits comprehensive quality assurance.
Professional presentation
Document includes company branding, clear data tables, chromatogram, mass spectrum, product photo, and signed by Principal Chemist Stephen Schmidt. Layout is professional and organized.
