Public COA audit
PT-141 · Bremelanotide
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 83%
- Panels
- 2/7
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "Issue date after sample receipt". 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 · 1 passed · 0 failed · 1 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).
Confirmed by UPLC and MS
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
Not quantified on this page
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.
Issue date after sample receipt
Analysis conducted date (05/17/2026) is 5 days before received date (05/22/2026). This temporal inconsistency is unusual but may be a data entry error or formatting issue.
Purity percentage not stated
UPLC chromatograms are shown but no quantitative purity percentage is printed on this page. This may be a partial/identity-only report.
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.
Identity confirmed by orthogonal methods
Both UPLC retention time and mass spectrometry data are provided, showing expected molecular ion peaks consistent with PT-141.
Established testing laboratory
Horizon Analytical is a known third-party analytical testing laboratory in the USA with searchable online presence.
Batch number clearly stated
Lot number APR-9495443-P is clearly printed with client name American Peptide Research.
Professional presentation
Document has consistent branding, clear chromatograms, and professional layout typical of legitimate analytical reports.
