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).
Epithalon confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.632%
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.
≤ 0.05 EU/mL (both replicates)
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 99.632% with supporting chromatogram showing single dominant peak at retention time ~1.25 min
Mass spec confirmation
Mass spectrum shows [M+H]+ at 390.88 m/z, consistent with Epithalon identity
Endotoxin testing performed
Duplicate endotoxin testing per USP <85> guidelines, both replicates pass at ≤ 0.05 EU/mL threshold
Batch documentation
Lot number 0002 clearly stated, net peptide content 9.13 mg documented
Appropriate turnaround time
Sample received 11/19/2025, reported 11/21/2025 (2-day turnaround)
Lab identification
Freedom Diagnostics with verification URL and contact email provided, signed by Stephen Schmidt, Principal Chemist
Professional presentation
Document includes product photos, chromatograms, mass spectrum, and appropriate research-use disclaimers
Limited testing scope
Heavy metals, microbial, sterility, and residual solvent/water testing not performed - common for basic research peptide COAs but limits comprehensive quality assessment
Two accession numbers for same lot
Page 1 shows accession 2511190029, page 2 shows 2511190030, both for same product lot 0002 - appears to be separate purity and endotoxin reports rather than duplicate testing
