Public COA audit
BPC-157 · TB-500
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 88%
- Panels
- 2/7
- Purity (printed)
- 99.36%
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 results". 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).
BPC-157 confirmed; TB-500 confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
BPC-157: 99.36%; TB-500: 99.12%
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.

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 results
BPC-157 at 99.36% and TB-500 at 99.12% are both excellent purity values for research peptides and meet the ≥98% specification.
Identity confirmed by UPLC/MS
Both compounds show UPLC chromatograms with clean single peaks and MS spectra with expected molecular ion patterns. BPC-157 shows m/z consistent with its ~1419.5 g/mol weight, TB-500 shows m/z consistent with ~4963 g/mol.
Same lot number for two different compounds
Both BPC-157 and TB-500 share the identical lot number B-4339222-P. While the '-P' suffix suggests this is a purity-focused report (possibly part of a split testing protocol), it is unusual for two chemically distinct compounds to carry the same lot identifier unless they were co-synthesized or this represents a batch identifier rather than a unique sample ID.
Sample and analysis dates are valid
Lab received date and analysis conducted date are both 06/22/2026, which is before the current date of 2026-09-05. Same-day turnaround is plausible for UPLC/MS purity testing.
Lab verification not independently confirmed
Horizon Analytical is listed with [email protected] and a searchable URL horizonanalytical.com. The document includes a QR code for validation. However, I cannot verify the lab's actual existence, accreditation status, or whether the URL is operational from this document alone.
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
The document is well-formatted with clear tables, chromatograms, mass spectra, and a signature from Aleksey Yevtodiyenko PhD. The layout is consistent across both compound sections.
