BPC-157 — Certificate of Analysis

Lot BC10-2026-001 of BPC-157 assayed at 99.72% peptide purity by RP-HPLC against a ≥95.0% release specification, 4.72 percentage points clear of it. Released 07/15/2026 by ILS Laboratories, ISO/IEC 17025 Accredited. Synthetic pentadecapeptide (GEPPPGKPADDAGLV) derived from a gastric protein fragment, used in laboratory tissue-repair and cytoprotection research.

Net peptide content measured 10.46 mg against a 10 mg label — the mass of actual peptide in the vial, as distinct from salts, water and counter-ions. It is reported rather than graded, so it carries no pass/fail.

Full QC panel

Analyte	Specification	Result	Status
Peptide Purity (HPLC)	≥ 95.0%	99.72%	Pass
Identity (HPLC-RTM)	BPC-157 Confirmed	Confirmed	Pass
Net Peptide Content	Report Only	10.46 mg	—
Fentanyl Screen	Immunoassay, 50 ng/mL cutoff	Not Detected	Pass

Sterility & endotoxin

Test	Specification	Result	Status
Sterility (PCR)	No Growth	No Growth	Pass
Endotoxin (USP <85>)	Report Result	NMT 0.05 EU/mL	Reported

Endotoxin is reported as a measured value rather than graded pass/fail: acceptable limits depend on route and matrix, and no universal threshold applies to research-use material. The laboratory reports the figure and leaves the judgement to you.

Elemental impurities

Panel	Method	Result	Status
Arsenic, cadmium, chromium, lead, mercury	ICP-MS, USP <233>	5 of 5 under limit	Pass

Per-element measurements are on the signed certificate below and in the laboratory's own record.
