Public COA audit
TB-500
Audited September 5, 2026
Missing panels or key metadata — not enough evidence to treat this as a full certificate.
- Legitimacy
- 62
- Confidence
- 82%
- Panels
- 2/7
Scored lower because the file is incomplete or not a full COA, limited panel coverage (2/7), 2 soft concerns, and notable note: "No numerical purity stated". To improve: upload the full certificate (or the matching sibling purity/endotoxin report) and 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 · 0 passed · 0 failed · 2 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 · result on file · core
Compound identity confirmed (e.g. HPLC, mass spec).
MS2 ES+ TIC 2.1565, MS2 ES+ TIC 1.9827, MS2 ES+ TIC 2.4269
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
ELSD Signal Range: 292 shown, no numerical purity stated
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.
No numerical purity stated
UPLC chromatogram is shown with ELSD signal range 292, but no percentage purity value is provided on this page. This is an identity/method development report rather than a complete purity quantification.
Identity methods present
UPLC chromatograms and mass spectrometry data are shown. MS peaks at m/z 1653.21 and related fragments are consistent with TB-500 peptide analysis.
Lot number present
Lot APR-7332292 clearly stated with PubChem CID 16132341 reference.
Dates are valid
Received and analysis dates both 03/27/2026, which is before the current date of 2026-09-05.
Lab identified
Horizon Analytical with contact email and searchable URL provided. Lab claims US-based operation.
Purity/identity report file
This certificate file looks like a purity/identity report. Many vendors publish a separate endotoxin report for the same lot — missing endotoxin on this file alone does not prove the lot was never tested.
Professional presentation
Clean layout with lab branding, chromatograms, and mass spec data professionally formatted. Client identified as American peptide research / Americanpeptideresearch.com.
