LL-37 Dosing Guide

Standard: 100–500mcg subcutaneously 1–2x daily. Start low (100mcg) due to potential injection site reactions. Titrate up over 1–2 weeks.

Blood markers to track

WBC/differentialhs-CRPVitamin D (related signaling)

Note: Can cause injection site pain and redness - titrate slowly. Antimicrobial and wound-healing dual action.

Frequently Asked Questions

What is the standard LL-37 dose?

Standard: 100–500mcg subcutaneously 1–2x daily. Start low (100mcg) due to potential injection site reactions. Titrate up over 1–2 weeks.

How do I reconstitute LL-37?

Add 2mL of bacteriostatic water to a 5mg vial of LL-37 to get a concentration of 2500 mcg/mL. This gives 500mcg per 20 units on a 100-unit insulin syringe.

What blood markers should I track while running LL-37?

Common biomarkers tracked alongside LL-37 protocols include WBC/differential, hs-CRP, Vitamin D (related signaling). Establishing a baseline panel before starting and re-drawing labs at consistent intervals lets you measure changes against your own reference point, generic lab ranges are less informative than your personal trend over time. MyProtocolStack tracks each of these biomarkers in the context of your active LL-37 protocol.
