Public COA audit
BPC 157
Audited September 5, 2026
Missing panels or key metadata — not enough evidence to treat this as a full certificate.
- Legitimacy
- 45
- Confidence
- 75%
- Panels
- 1/7
- Purity (printed)
- 99.45%
Scored poorly because the file is incomplete or not a full COA, limited panel coverage (1/7), 2 critical findings, and notable note: "High HPLC purity reported". 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 · 0 passed · 0 failed · 1 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
Tested · result on file · core
Reported purity percentage for the analyte.
99.45%
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 HPLC purity reported
99.45% purity by HPLC with clear chromatogram showing dominant peak at 12.77 min and minor impurities totaling <0.6%
No lot/batch number provided
Lot number field shows 'N/A', which is highly irregular for a legitimate COA and prevents traceability
No identity confirmation
Document shows only purity testing (HPLC chromatogram). No mass spectrometry, amino acid analysis, or other identity confirmation method is present
Limited testing scope
Only purity panel present. Missing identity, heavy metals, microbial, endotoxin, sterility, and residual solvent/water testing
No issue date
Analysis date provided (2023-08-25) but no report issue date or analyst signature/approval date
Minimal documentation
Report lacks standard COA elements: no specifications/acceptance criteria, no pass/fail statements, no analyst signatures, no quality assurance approval
