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.
< 0.050 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.
Professional lab presentation
BioRegen appears to be a legitimate independent testing laboratory with professional formatting, contact information, and verification mechanisms including QR code and validation key.
Complete batch information
Sample lot number 35-3-45958 clearly documented with sample concentration (20 mg) and company name (Biolongevity Labs).
Valid test date
Test date of 11/19/2025 is within acceptable range and matches analyst signature date.
Endotoxin testing passed
Endotoxin level < 0.050 EU/mL is well below the acceptable threshold of 0.25 EU/mL. Test includes proper controls (spike recovery 88% Pass, test suitability Pass).
Limited testing scope
This is a specialized endotoxin-only report. No identity, purity, heavy metals, microbial, sterility, or residual solvent testing is included. This is appropriate for a focused endotoxin analysis but does not constitute a comprehensive COA.
Professional documentation
Report includes Report ID (BL-ENDO-251911-167), validation key (BIOLABS2010), analyst signature, instrument details (Endosafe nexgen-PTS SN: 25201216), and verification instructions.
