LL-37 5mg: A Human Cathelicidin Peptide
LL-37 is the only cathelicidin peptide found in humans. It comes from a bigger protein called hCAP18. The body stores hCAP18 inside neutrophil granules, then cuts it down to the active 37 amino acid piece. That active piece is LL-37.

Quick Facts
Name: LL-37
Also called: CAP-18, human cathelicidin
Length: 37 amino acids
Formula: C205H340N60O53
Weight: about 4493.34 g/mol

What Makes It Different
LL-37 carries a positive charge. It also has an amphipathic structure, meaning part of it likes water and part doesn't. That combination lets it interact with bacterial membranes in lab studies. Researchers note it resists breakdown well, even compared to other antimicrobial peptides.
What Labs Study It For
Researchers use LL-37 to look at:
Membrane interaction and pore formation
Antimicrobial mechanism studies
Innate immune signaling, in vitro
Wound healing pathway research
Structure activity work on cathelicidin derived peptides
Some labs also pair LL-37 with Melanotan 2, especially when comparing receptor based and membrane based peptide research side by side.
Regulatory Status
The FDA hasn't approved LL-37 for treating anything. It's sold strictly as a research compound.
Legal and Safety Info
Not a supplement, just a raw research compound. Keep away from kids. Long term safety data is limited, so only trained lab personnel should handle this.
Buying this means agreeing to use it legally, for research only.
