The Science
LL-37 is the only known antimicrobial peptide derived from cathelicidin in humans. This naturally occurring defense molecule is produced by various cells throughout the body and represents a critical component of the innate immune system’s first-line defense against pathogens. The peptide consists of 37 amino acids and demonstrates remarkable broad-spectrum antimicrobial activity against bacteria, viruses, and fungi.
Beyond its antimicrobial properties, LL-37 plays essential roles in wound healing, immune modulation, and tissue repair. The peptide promotes angiogenesis (blood vessel formation), facilitates epithelial cell migration, and helps regulate inflammatory responses. It also exhibits chemotactic properties, attracting immune cells to sites of infection or injury, and demonstrates the ability to neutralize bacterial toxins that would otherwise cause tissue damage.
Therapeutic administration of LL-37 aims to support the body’s natural defense mechanisms, particularly in individuals with compromised immune function, chronic wounds, or recurrent infections. Medical supervision ensures appropriate dosing and monitoring for this powerful immune-modulating peptide that represents a novel approach to infection management and tissue regeneration beyond traditional antibiotic therapy.

How It Works
A dual-action antimicrobial and immune-modulating peptide that provides comprehensive defense and healing support.
Disrupts bacterial cell membranes through electrostatic interactions, demonstrating broad-spectrum activity against gram-positive and gram-negative bacteria, viruses, and fungi without promoting resistance.
Acts as an immunomodulator by recruiting immune cells to infection sites, regulating inflammatory cytokine production, and enhancing the body’s natural defense mechanisms against pathogens.
Stimulates angiogenesis, accelerates epithelial cell migration, promotes keratinocyte differentiation, and enhances tissue remodeling for faster healing of chronic wounds and tissue injuries.
Clinical Benefits
Provides antimicrobial activity against bacteria, viruses, and fungi without promoting antibiotic resistance, offering a novel approach to infection management.
Accelerates tissue repair through multiple mechanisms including angiogenesis promotion, cell migration stimulation, and collagen deposition enhancement for faster wound closure.
Modulates immune responses by recruiting defense cells, regulating inflammation, and enhancing the body’s natural ability to fight infections and heal damaged tissue.
Helps regulate inflammatory pathways to prevent excessive tissue damage while maintaining appropriate immune responses necessary for healing and pathogen clearance.
Demonstrates the unique ability to penetrate and disrupt bacterial biofilms, addressing chronic infections that are resistant to conventional antibiotic therapy.
Binds and neutralizes bacterial endotoxins and other pathogenic molecules that cause inflammation and tissue damage, protecting healthy cells during infection.

Questions
Unlike conventional antibiotics that target specific bacterial metabolic pathways, LL-37 works through a physical mechanism by disrupting bacterial cell membranes, making it virtually impossible for pathogens to develop resistance. Additionally, LL-37 provides immune-modulating benefits and wound healing properties that antibiotics lack. It can address viral and fungal infections alongside bacterial threats, offers anti-inflammatory effects, and supports tissue regeneration—creating a comprehensive therapeutic approach beyond simple pathogen elimination.
LL-37 is ideal for individuals with chronic non-healing wounds, recurrent infections not responding to conventional treatment, compromised immune function requiring additional support, biofilm-related infections, skin conditions with infectious components, or those seeking antimicrobial therapy without antibiotic resistance concerns. Our physicians evaluate your specific medical history, infection patterns, immune status, and therapeutic goals to determine if LL-37’s unique mechanism of action is more appropriate than conventional antimicrobial approaches for your situation.
LL-37 is administered via subcutaneous injection, typically 2-3 times per week depending on your specific protocol and therapeutic needs. The peptide comes as a lyophilized powder that you’ll reconstitute with bacteriostatic water before injection. Our medical team provides comprehensive training on proper reconstitution technique, injection methodology, site rotation, storage requirements (refrigeration), and sterile handling procedures to ensure safe and effective self-administration at home throughout your treatment protocol.
LL-37 is generally well-tolerated as it’s a naturally occurring peptide in the human body. The most common side effects are mild injection site reactions including temporary redness, slight swelling, or minor discomfort that typically resolve within hours. Some patients report temporary fatigue as the immune system responds to therapy. Serious adverse effects are rare but could include allergic reactions or immune activation symptoms. Our physicians monitor your response carefully throughout treatment, adjusting dosing if needed to optimize benefits while minimizing any potential reactions.
LL-37 protocols typically run 4-8 weeks for acute infections or wound healing support, while chronic conditions may benefit from 8-12 week courses or longer with physician oversight. The duration depends on your condition severity, healing response, infection resolution, and therapeutic goals. Chronic wound healing might require extended protocols, while acute infection support could respond to shorter intensive courses. Some patients use maintenance protocols for ongoing immune support. Our doctors design personalized treatment plans based on your response and adjust duration to achieve optimal outcomes.
LL-37 can often be safely combined with other therapies including conventional antibiotics for severe infections, wound care protocols, immune support supplements, and regenerative treatments when properly coordinated. However, you must disclose all current medications, supplements, antimicrobial treatments, and immune-affecting therapies to our physicians during consultation. We’ll review potential interactions and design an integrated protocol that maximizes healing while maintaining safety. Some therapies like wound debridement, proper nutrition, and immune support may enhance LL-37’s effectiveness.
Many patients notice improvements within 1-3 weeks of starting LL-37 therapy, with continued progress throughout the protocol duration. For wound healing applications, reduced inflammation and improved tissue quality may appear within 7-14 days, with continued healing progression over weeks. Infection-related symptoms often improve within 2-3 weeks as antimicrobial effects accumulate. However, timelines vary based on condition severity, infection chronicity, overall immune function, and wound complexity. Complete therapeutic benefits including full tissue regeneration and infection resolution typically develop over the full 4-8+ week protocol.
