Side-by-side differences
| Aspect | BPC-157 | GLP3 |
|---|---|---|
| Peptide length | 15 residues | 39 residues |
| Molecular weight | 1419.55 g/mol | 4731.4 g/mol |
| Molecular formula | C62H98N16O22 | C221H343N51O64 |
| CAS number | 137525-51-0 | 2381089-83-2 |
| Aib residues | None | Multiple (drives α-helical stability) |
| Reconstitution | Direct in water | Brief alkalinization recommended |
| Aggregation | Minimal at <50 mg/mL | Self-associates above ~5 mg/mL |
| Stability vs proteases | Highly stable (Pro-rich) | Standard susceptibility |
When researchers choose each
BPC-157 is the smaller, easier-to-handle reference for proline-rich short peptide analytics. GLP3 is selected for studies involving longer Aib-stabilized peptide backbones and receptor-binding analytics where conformational stability matters.
