Injectable: Once daily subcutaneous Cycle Duration 2-8 weeks depending on wound healing progress Storage Lyophilized: 2-8°C. Reconstituted: 2-8°C, maintain sterility ## Molecular Information Length 37 amino acids Type Cationic antimicrobial peptide Half-Life Short (rapid proteolytic degradation) ### Modifications Derived from hCAP18 protein ## Research Indications The following information is derived from published scientific literature and is provided for educational and research reference purposes only. It does not constitute medical advice, diagnosis, or treatment recommendations. These peptides are not approved for human use and are sold exclusively for in-vitro laboratory research. Wound Healing Immunity Skin Health ## Dosing Protocols ### topical Topical application is the most established route, providing direct access to wound sites with minimal systemic exposure. | Goal | Dose | Frequency | Route | | --- | --- | --- | --- | | Wound healing - Standard | 0.5mg/mL gel/cream | Daily to twice weekly | Direct wound application | | Wound healing - Intensive | 1.6mg/mL gel/cream | Daily | Direct wound application | #### Key Tips - Direct access to wound site - Minimal systemic exposure - Most established clinical data Reconstitution Instructions ### injectable Subcutaneous injection provides systemic distribution for immune modulation. Limited clinical data compared to topical. | Goal | Dose | Frequency | Route | | --- | --- | --- | --- | | Systemic immune support | 100-150mcg | Once daily | SubQ | #### Key Tips - Systemic distribution - Abdomen, thigh, upper arm injection sites Reconstitution Instructions ## Peptide Interactions #### BPC-157 Synergistic Enhanced wound healing through complementary mechanisms. #### TB-500 Synergistic Combined anti-inflammatory and healing effects. #### Conventional Antibiotics Synergistic FICI values 0.25-0.5 against resistant bacteria when combined. #### Vitamin D3 Synergistic Acts as cofactor for endogenous LL-37 production. #### Lactoferrin Compatible Safe combined use with no negative interactions. #### Physiological Salt Solutions Monitor High salt concentrations may reduce antimicrobial activity. #### Amino Acid Solutions Avoid Physical incompatibility, especially with IV formulations. ## What to Expect Week 1-2 Reduced bacterial load, initial wound bed preparation Week 2-4 Increased granulation tissue formation, epithelial migration Week 4-6 Significant wound size reduction Week 6-8 Continued healing toward wound closure ## Side Effects & Safety #### Common Side Effects - Generally well-tolerated - Mild injection site reactions (injectable) - Local irritation at application site (topical) #### Monitoring - Injection site reactions and excessive irritation - Signs of wound infection - Allergic reactions or contact dermatitis - Wound healing progress #### Stop Signs - Severe injection site reactions with spreading inflammation - Allergic reaction signs (rash, difficulty breathing, swelling) - Persistent flu-like symptoms - Signs of wound infection (increased redness, warmth, drainage) - Worsening wound condition or delayed healing - Unusual pain or irritation at application site #### Contraindications - Pre-existing hypersensitivity to peptides - Compromised immune status (relative contraindication) - Non-sterile wound environments ## Quality Checklist #### Good Signs - Sterile, clear formulation - ≥98% purity by HPLC - White to off-white lyophilized powder - Proper cold chain maintenance (2-8°C) - Appropriate gel base compatible with peptide activity - Clinical-grade concentrations (0.5-1.6mg/mL) #### Warning Signs - Brief room temperature exposure acceptable if promptly refrigerated - Homemade topical formulations may lack sterility #### Bad Signs - Discolored or cloudy solutions - Yellow discoloration or visible particles - Pre-mixed liquid formulations (LL-37 unstable long-term) - Non-sterile preparations - Microbial contamination ## Research & References ### Latest Research 2025 #### LL-37: Master Antimicrobial Peptide Review International Journal of Antimicrobial Agents Comprehensive review of broad functions from infection to cancer immunity. ### Key References 1. 2014 #### Venous Leg Ulcer Trial - Grönberg et al.
