Public COA audit
Vilon
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 1/7
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (1/7), and 1 soft concern. To improve: include identity, purity, and endotoxin at minimum.

Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
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 certificate file · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Purity
Not on this certificate file · core
Reported purity percentage for the analyte.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Microbial
Not on this certificate file
Bioburden / microbial limits testing.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
< 0.050 EU/mL
Sterility
Not on this certificate file
Sterility testing where applicable.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Residual solvent / water
Not on this certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
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 on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
Endotoxin testing present and passed
Chromogenic LAL assay performed using Endosafe nexgen-PTS instrument. Result < 0.050 EU/mL is well below the specification of < 0.25 EU/mL. Test suitability passed with 78% spike recovery.
Endotoxin-only report scope
This is a specialized endotoxin testing report only. Identity, purity, heavy metals, microbial, sterility, and residual solvent panels are not included in this document. This is common for split testing where endotoxin is performed separately from other analyses.
Professional lab presentation
BioRegen is presented as an independent testing laboratory with contact information, website, validation key, and QR code for verification. Report includes detailed reagent information and instrument serial number.
Complete sample identification
Sample lot number 47-3-45951 clearly documented with company name (Biolongevity Labs), sample name (Vilon), concentration (20 mg), and vials received (1).
Test and signature dates consistent
Test date and analyst signature date both show 11/19/2025, which is consistent and within normal timeframes (before the current date of 2026-09-05).
Professional report structure
Report includes proper sections for test information, sample information, reagent information, quantitation results, interpretation, and analyst signature. QR code and validation key provided for authenticity verification.
