LL-37 (5mg) Dosage Protocol
LL-37 is a human cathelicidin antimicrobial peptide with 37 amino acids. It plays a role in innate immunity, wound healing, and has demonstrated antimicrobial activity against bacteria, viruses, and fungi.
Add 2.5 mL bacteriostatic water → 2 mg/mL (2000 mcg/mL)
50-200 mcg daily for research protocols
At 2 mg/mL: 2.5 units = 50 mcg, 10 units = 200 mcg
Lyophilized: -20°C; Reconstituted: 2-8°C for up to 2 weeks
| Week | Daily Dose | Units (per injection) |
|---|---|---|
| Weeks 1-2 | 50 mcg daily | 2.5 units (0.025 mL) |
| Weeks 3-4 | 100 mcg daily | 5 units (0.05 mL) |
| Weeks 5-8 | 150-200 mcg daily | 7.5-10 units |
- 1Draw 2.5 mL bacteriostatic water with a sterile syringe
- 2Inject slowly down the vial wall to prevent foaming
- 3Gently swirl until fully dissolved - do not shake
- 4Label with date and concentration, refrigerate immediately
LL-37 is the only human cathelicidin, produced by epithelial cells and immune cells. It disrupts microbial membranes and modulates immune responses. Research shows broad-spectrum antimicrobial activity and roles in wound healing, angiogenesis, and immune regulation.
