BPC-157 vs LL-37

BPC-157 vs LL-37: tissue repair peptide vs antimicrobial/immune peptide. BPC-157 focuses on healing via growth factor upregulation; LL-37 provides antimicrobial protection and innate immune modulation.

Mechanism Comparison

BPC-157: upregulates VEGF, EGF, FGF at injury sites, promotes angiogenesis, modulates nitric oxide. LL-37: direct membrane disruption of bacteria/viruses, promotes wound healing via keratinocyte migration, modulates TLR4 signaling.

Research Applications

BPC-157: musculoskeletal repair, gut healing, neurological research. LL-37: antimicrobial research, wound healing, inflammatory skin conditions, sepsis models.

Combination Protocol

BPC-157 and LL-37 can be combined for wound healing research where both tissue repair and infection prevention are relevant endpoints. BPC-157: 250–500 mcg/day. LL-37: 0.5–2 mg/day subcutaneously or topical.
