BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide consisting of 15 amino acids (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val), with CAS number 137525-51-0 and molecular weight of approximately 1419.53 Da. It is a partial sequence derived from human gastric juice protein BPC. Sold for research use only.

What purity is your BPC-157?

Our BPC-157 is independently tested by Janoshik Analytical, an ISO 17025-accredited laboratory, and verified at 99.81% purity via HPLC analysis. The Certificate of Analysis is published on the product page and can be independently verified on Janoshik's website.

How should BPC-157 be stored?

Lyophilized (freeze-dried) BPC-157 should be stored at -20°C for long-term storage or 2-8°C (refrigerator) for short-term storage. Keep away from light and moisture. Once reconstituted, store refrigerated and use within 30 days. BPC-157 is noted for its stability in aqueous solution compared to many other peptides.

Is BPC-157 third-party tested?

Yes. Every batch of BPC-157 is independently tested by Janoshik Analytical, an ISO/IEC 17025 accredited laboratory with no financial ties to Chameleon Peptides. Testing includes identity confirmation via mass spectrometry and purity analysis via HPLC. COA is downloadable on the product page.

Brief Description

Pentadecapeptide derived from a protective protein found in gastric juice, studied in over 100 published papers for its effects on tissue repair pathways — including upregulation of growth factor receptors (VEGF, EGF) and modulation of the nitric oxide system. Research areas include tendon and ligament repair, gastrointestinal mucosal protection, bone healing, and neuroprotective mechanisms in injury models. For research use only — not for human consumption.

Batch 002 Transparency Note

Transparency update

Due to recent supply chain and international shipping disruptions, some Batch 002 inventory may include vials produced at different points within our supplier’s production cycle. As a result, researchers may notice minor packaging variations, including differences in vial caps.

These products were sourced from the same established manufacturers we have worked with for ongoing quality and third-party testing. That said, we want to be transparent that Batch 002 may not represent a single uninterrupted production run.

We are already working with our suppliers to strengthen batch-control, packaging, and documentation protocols before Batch 003.
