Public COA audit
PT-141
Audited September 5, 2026
Missing panels or key metadata — not enough evidence to treat this as a full certificate.
- Legitimacy
- 62
- Confidence
- 85%
- Panels
- 1/7
Scored lower because the file is incomplete or not a full COA, limited panel coverage (1/7), 3 soft concerns, and notable note: "Endotoxin-only report". 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.
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.
<0.05 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-only report
This COA is scoped to endotoxin testing only (lot suffix -E). It does not include purity, identity, or other panels. This is a split report format; the vendor may have issued separate purity/identity reports for this lot under a different suffix (e.g., B-3230947-P).
Lot number present
Lot B-3230947-E clearly stated with -E suffix indicating endotoxin-focused report.
Dates valid
Lab received date 2026-06-28 and analysis conducted date 2026-07-02 are both on or before 2026-09-05 and are logically sequenced.
Lab identified
Horizon Analytical with contact email and verification URL provided. Signed by Aleksey Yevtodiyenko PhD.
Endotoxin result acceptable
Endotoxin result <0.05 EU/mL is within typical acceptable limits for research peptides.
No purity data
This report does not contain HPLC or purity percentage. For complete quality assessment, a companion purity/identity report should be reviewed.
No identity confirmation
No MS, NMR, or other identity verification method shown in this endotoxin-only report.
