Synthetic peptide fragments
BPC-157 research peptide
BPC-157 is a synthetic pentadecapeptide. Its sequence corresponds to a partial sequence of a larger protein, termed body protection compound, that was first isolated from human gastric juice. It is one of the most widely cited research peptides in the preclinical literature.
For in-vitro laboratory research only. Not for human or veterinary use.

Frequently asked questions
What is BPC-157?
BPC-157 is a synthetic pentadecapeptide. Its sequence corresponds to a partial sequence of a larger protein, termed body protection compound, that was first isolated from human gastric juice. It is one of the most widely cited research peptides in the preclinical literature.
How is each BPC-157 lot tested?
Every lot is tested at an ISO/IEC 17025 accredited third-party laboratory against an eight-assay panel: HPLC-UV purity, quantitative net peptide content, LC-MS identity, appearance, a fentanyl screen, heavy metals by ICP-MS, sterility by PCR, and endotoxin by LAL. The certificate is published before the lot ships.
How do I verify the certificate for my BPC-157 vial?
Scan the QR code on the vial label to open the certificate for that exact lot, or search the lot number in the North Wall COA library.
Is BPC-157 for human use?
No. North Wall sells this compound solely for in-vitro laboratory research by qualified researchers aged 21 and over. It is not for human or veterinary use, and North Wall does not provide use, preparation, or dosing guidance.
