BPC-157 vs LL-37: Head-to-Head Comparison
BPC-157 is primarily a healing peptide that promotes tissue repair, while LL-37 is a human cathelicidin antimicrobial peptide that serves as a first-line immune defense. LL-37 has direct antimicrobial activity against bacteria, fungi, and viruses, while BPC-157 focuses on structural tissue recovery.
Side-by-Side Comparison
| Dimension | BPC-157 | LL-37 |
|---|---|---|
| Evidence Level | Extensive animal studies | Human endogenous peptide, well-characterized; clinical studies ongoing |
| FDA Status | Not approved | Not approved as therapeutic |
| Mechanism | Angiogenesis, growth factor modulation, NO pathway | Membrane disruption of pathogens, immune cell recruitment, wound healing |
| Primary Use | Tissue repair: gut, tendon, ligament | Antimicrobial defense, biofilm disruption, wound healing |
| Antimicrobial Activity | Not a primary mechanism | Broad-spectrum: antibacterial, antifungal, antiviral |
| Side Effects | Minimal in animal studies | Potential cytotoxicity at high concentrations, injection site reactions |
