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
- 92
- Confidence
- 88%
- Panels
- 2/7
- Purity (printed)
- 99.21%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 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.
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).
PT-141 confirmed by MS (m/z peaks consistent with C50H68N14O10, MW ~1025.2)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.21%
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 confirmed
99.21% purity by UPLC exceeds >98% specification. This is normal for research-grade peptides and is supported by clean chromatogram.
Identity confirmed by UPLC/MS
Mass spectrum shows expected molecular ion peaks (1024.06 m/z) consistent with PT-141 (bremelanotide) formula C50H68N14O10. PubChem CID 9941379 correctly cited.
Lot number clearly stated
Lot B-3230947-P with -P suffix indicates this is a purity/identity-focused report. Quantity 10.12mg vs 10mg spec is within normal tolerance.
Dates are reasonable
Lab received 2026-06-28, analysis conducted 2026-07-02 (4-day turnaround). Both dates are on or before today (2026-09-05) and are plausible.
Lab identification present
Horizon Analytical with contact email and verification URL. Signed by Aleksey Yevtodiyenko PhD. QR code provided for validation.
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
Two-page report with clear chromatograms, mass spectrum, and tabular results. Formatting is consistent with legitimate analytical lab reports.
