- Tendon/Ligament Repair Models
- Superior. Increases collagen synthesis, VEGF expression, and tensile strength by 60–85% vs controls
- No direct effect. Antimicrobial action irrelevant to connective tissue regeneration
- BPC-157
- Multiple controlled animal studies (J Physiol Pharmacol 2020)
- Bacterial Wound Infection Models
- No antimicrobial activity. Cannot reduce bacterial load
- Superior. Reduces bacterial CFU by 70–90% within 24 hours via membrane disruption
- LL-37
- In vitro and in vivo antimicrobial assays (J Immunol 2017)
- Gastric Ulcer Healing (Rodent Models)
- Superior. Accelerates epithelial closure and reduces inflammation markers by 55–70%
- No documented efficacy in gastric healing. Not studied for this application
- Controlled trials in rats (Eur J Pharmacol 2019)
- Immune Modulation Research
- Indirect effect via NO pathway modulation. Not a primary mechanism
- Direct effect. Activates FPRL1 receptors, recruits neutrophils/monocytes, modulates cytokine release
- Receptor binding and chemotaxis studies (Front Immunol 2021)
- Bone Healing/Fracture Models
- Moderate. Enhances angiogenesis around fracture sites, improving healing by 30–40%
- No direct bone regeneration effect. Antimicrobial role in preventing infection post-surgery
- BPC-157 for healing; LL-37 for infection prophylaxis
- Rodent fracture studies (Bone 2018)
- Storage Stability for Long-Term Protocols
- Excellent. Stable at room temp for 90 days lyophilized; 28 days reconstituted at 2–8°C
- Poor. Requires −20°C storage lyophilized; reconstituted aliquots lose 15% potency/week
- BPC-157 for protocols requiring multiple doses over weeks
- Peptide stability assays (vendor technical data)
