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.
1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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
Not on this COA · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Purity
Not on this COA · core
Reported purity percentage for the analyte.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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.
< 0.01 EU/mL
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.
Endotoxin testing performed
Chromogenic LAL assay shows < 0.01 EU/mL, passing the 0.1 EU/mL threshold. Controls (positive and negative) performed correctly.
Professional lab presentation
BioRegen branding, contact information, validation key (BIOLABS2010), and QR code for verification all present.
Test date within acceptable range
Test date 04/09/2025 is before today (2026-07-29) and appears legitimate.
No batch/lot number provided
Document does not specify a batch or lot number for the tested product SS-31, which is typical for full COAs but may be acceptable for single-panel endotoxin reports.
No purity or identity testing
This is a single-panel endotoxin report only. No HPLC purity, mass spec identity, or other characterization data is included. This is common for supplemental testing but not a complete COA.
Clear methodology and reagent details
Kit product number (A39553 Thermo Fisher), endotoxin standard (E.coli O111:B4), detection range, and plate reader specifications all documented.
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (476 days) — consider whether a retest is warranted for this batch.
