BPC-157: Chemical Profile, Peptide Sequence and Quality Testing Overview
A technical overview of BPC-157 covering its chemical identity, peptide sequence, analytical characteristics and common quality documentation used for research materials.

Overview
BPC-157 is a synthetic peptide that has become widely referenced in peptide research discussions. As a 15-amino-acid peptide sequence, its identity can be described through several key chemical parameters, including its amino acid sequence, molecular formula, molecular weight and analytical testing data.
For researchers evaluating peptide materials, these technical identifiers provide a foundation for understanding what a peptide is and
Chemical Identity of BPC-157
Every peptide has its own molecular fingerprint. For BPC-157, the most commonly referenced identifiers include:
| Parameter | Value |
|---|---|
| Name | BPC-157 |
| Peptide Length | 15 amino acids |
| CAS Number | 137525-51-0 |
| Molecular Formula | C62H98N16O22 |
| Molecular Weight | Approximately 1419.5 g/mol |
| Sequence | GEPPPGKPADDAGLV |
These identifiers are commonly used when comparing product specifications, analytical documents and research materials from different sources.
Understanding the BPC-157 Peptide Sequence
Unlike small chemical compounds, peptides are defined by the order of their amino acids.
The BPC-157 sequence is:
GEPPPGKPADDAGLV
This sequence represents the arrangement of 15 amino acid residues that form the peptide chain.
In peptide analysis, sequence information is an important reference point because even small differences in amino acid order can result in completely different compounds.
Why CAS Number and Molecular Weight Matter
When reviewing peptide information, product names alone are not always sufficient.
Different suppliers may use similar naming conventions, so researchers often compare multiple identifiers.
For BPC-157, these include:
CAS Number
CAS Number:
137525-51-0
A CAS number acts as a standardized reference for chemical identification.
Molecular Weight
Molecular weight:
Approximately 1419.5 g/mol
Mass spectrometry testing is commonly used as an analytical method to confirm whether the measured molecular mass corresponds with the expected value.
Quality Documentation for BPC-157
When evaluating peptide materials, technical documentation is an important part of the review process.
Common documents include:
Certificate of Analysis (COA)
A COA provides batch-specific testing information.
Typical information may include:
Product name
Batch number
Test date
Test results
Analytical methods
A reliable COA should correspond to the specific batch being supplied rather than a generic document.
HPLC Purity Testing
HPLC (High Performance Liquid Chromatography) is commonly used for peptide purity analysis.
An HPLC report may show:
Purity percentage
Chromatographic profile
Testing conditions
The purpose is to evaluate the composition of the tested sample.
Mass Spectrometry Analysis
Mass spectrometry is commonly used for identity confirmation.
The technique measures the molecular mass of the sample and compares it with the expected molecular weight.
What Should Buyers Look for When Reviewing BPC-157 Information?
Before evaluating any peptide material, it is useful to review several aspects:
- Complete Product Identification
A professional specification sheet should clearly provide:
Product name
CAS number
Molecular information
Sequence information
- Batch-Specific Documentation
Quality documents should include traceable batch information.
Example:
Product:
BPC-157
Batch:
BPC157-XXXX
Testing:
HPLC / MS
Result:
Available
- Consistent Technical Data
Information across documents should match.
For example:
Product name
Molecular weight
Sequence
Testing information
should be consistent throughout the documentation.
