BPC-157 vs LL-37
Repair-focused peptide vs antimicrobial cathelicidin.
| Attribute | BPC-157 Body Protection Compound 157 | LL-37 Cathelicidin |
|---|---|---|
| Category | Healing & Recovery | Immune System & Inflammation |
| Best known for | Tendon, ligament, and gut healing research | Antimicrobial peptide research |
| In plain English | Think of BPC-157 as the peptide that researchers reach for when they want to study how soft tissue heals — tendons, ligaments, the gut lining, and connective tissue. It's been studied heavily in animal models for repair. | LL-37 is your body's natural antibiotic. Researchers study it for chronic infections, biofilms, and conditions where antibiotics fail. |
| How it works | In animal studies it appears to promote new blood vessel formation (angiogenesis), increase growth factor receptor expression (especially VEGFR2), and modulate the nitric oxide system. The net effect in research models is faster tissue repair. | Disrupts microbial membranes directly and modulates immune cell signaling. |
| Researchers study | Tendon-to-bone healing, ligament repair, gut barrier integrity, ulcer healing, muscle crush injury recovery, and brain–gut axis modulation. | Chronic infections, wound healing, biofilms, and autoimmune skin conditions. |
| Internet discussion | Online forums (Reddit's r/Peptides, AnabolicMinds, longevity Twitter) treat BPC-157 as the default 'recovery stack' addition. Stories range from rotator cuff and tendinopathy anecdotes to gut issues like IBS and leaky gut. | Discussed in chronic Lyme and biofilm contexts. |
