BPC-157 (Body-Protection Compound-157) is a synthetic pentadecapeptide — a chain of fifteen amino acids — that has become one of the most frequently referenced sequences in preclinical peptide research. It is derived from a partial sequence of a protein found in gastric juice, and researchers study it as a stable reference material in tissue-repair and gastrointestinal models.

Molecular profile

BPC-157 is a small, highly stable peptide often described in the literature by its 15-residue sequence. Its comparatively robust behaviour in aqueous solution is one reason it is a popular subject in laboratory work, where consistency of the reference standard is essential to reproducible results.

Areas of research interest

Published preclinical studies — predominantly in animal and in-vitro systems — have examined BPC-157 in contexts such as:

Connective-tissue and tendon-to-bone repair models
Gastrointestinal mucosa research
Angiogenesis (blood-vessel formation) pathways
Musculoskeletal recovery models

These investigations are exploratory and conducted in research settings. They do not establish any human use. HK Peptide groups sequences like this under recovery & repair research.

Why reference-standard purity matters

In any peptide study, the quality of the input material shapes the reliability of the output. Impurities, truncated sequences or moisture can confound results. That is why analytical HPLC purity and mass-spectrometry confirmation — documented in a certificate of analysis — are the baseline expectation for research-grade material. See our third-party lab reports for examples.

Handling and storage

Lyophilised (freeze-dried) peptides are typically stored cold and protected from light and moisture until reconstitution. Correct handling preserves sequence integrity across a study. Our research-supplies range covers the consumables commonly used alongside peptide reference standards.

Frequently asked questions

Is BPC-157 approved for human use?

No. BPC-157 is a research chemical supplied for laboratory and research use only. It is not an approved drug or supplement and is not intended for human consumption.

What does "pentadecapeptide" mean?

It simply means a peptide made of fifteen amino-acid residues. BPC-157 is a 15-residue synthetic sequence.

How is research-grade BPC-157 verified?

Reputable suppliers confirm identity and purity by HPLC and mass spectrometry, documented in a certificate of analysis (COA). HK Peptide provides third-party Janoshik reports.
