Overview
LL-37 is a naturally occurring human antimicrobial (host-defense) peptide, part of the cathelicidin family, studied for roles in fighting microbes and supporting wound healing.
How It's Thought to Work
It disrupts microbial membranes and modulates immune and inflammatory responses, and has been studied in wound-healing contexts.
What the Research Says
There is substantial academic research on LL-37 biology; consumer injectable 'research chemical' use is separate and far less studied.
Regulatory & Legal Status
Not an approved consumer product. Sold as a research chemical.
Safety Considerations
Limited human safety data for consumer use; can be pro-inflammatory in some contexts. Consult a qualified clinician.
