Short answer: For non-US professional research only, plan BPC-157 testing around sample identity, method purpose and provenance; do not use a “purity” headline as a complete qualification.
What to establish
Specify the exact research material, form, sample ID and question for the laboratory. Ask whether the method is designed for identity, chromatographic profile, content or another attribute. These outputs are not interchangeable.
What to verify
Retain supplier records, sample transfer notes, method description and the independent laboratory’s issued report. Compare the tested sample with the later lot offered and resolve differences in issuer, lot number or form.
Decision and next step
FDA has listed BPC-157 among bulk substances that may present significant safety risks in compounding. This guide gives no US compounding recommendation and no assurance of legality in any non-US jurisdiction; the research organization must assess its own rules.
Practical request
Use the points above to request a defined product, sample or lot record. Ask the document issuer to explain any discrepancy; do not infer regulatory suitability from a catalog listing.
