Public COA audit
Tesofensine · TESO-0001
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 2/7
- Purity (printed)
- 99.96%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "High purity result". 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.
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).
Tesofensine
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.96%
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
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.
High purity result
99.96% purity is excellent and within normal range for research-grade compounds. HPLC chromatogram shows single dominant peak consistent with high purity.
Identity confirmed
Compound identity confirmed as Tesofensine via LC-MS with UV detection. Mass spectrum shows expected molecular ion peak at m/z 328.1231 matching formula C17H23Cl2NO.
Unusual batch/lot format
Batch/Lot field shows 'White powder (30Ct Caps)' which describes physical form rather than a standard alphanumeric lot number. This is unconventional for analytical tracking.
Dates are valid
Sample received 2025-03-20, analysis conducted 2025-03-25. Both dates are reasonable and in proper sequence.
Lab verification needed
BioRegen presents as an independent testing lab with verification URL (bioregen.com/verify) and QR code. However, independent verification of lab accreditation and this specific COA is recommended.
Limited testing scope
This COA only covers identity and purity testing. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing is included. This is a purity/identity-scoped report only.
Professional presentation
Document has professional layout with clear branding, proper analytical data including chromatograms and mass spectrum, analyst signature, and security features (QR code, security key).
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (529 days) — consider whether a retest is warranted for this batch.
