| Aspect | BPC-157 | LL-37 (Cathelicidin) |
|---|---|---|
| Mechanism | BPC-157 works through multiple pathways including upregulation of growth factor expression, nitric oxide system modulation, and promotion of angiogenesis. It enhances tendon-to-bone healing and supports the formation of new blood vessels. | Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects. |
| Typical Dosage | Typical research dosages range from 250-500mcg administered 1-2 times daily. Both subcutaneous and oral administration have been studied. | Research protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections. |
| Administration | Can be administered subcutaneously near the injury site or systemically. Stable in gastric juice, making oral administration viable. | Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols. |
| Side Effects | Generally well-tolerated in research. Some reports of mild nausea or dizziness at higher doses. | Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses. |
