LL-37 vs Vesugen
Side-by-side comparison of key properties, dosing, and research.
- Summary
- LL-37 is the only known human cathelicidin antimicrobial peptide. It kills bacteria, fungi, and viruses by disrupting their membranes, while simultaneously modulating immune responses. Used for antimicrobial protection, immune priming, and wound healing.
- Vesugen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for blood vessels and the vascular endothelium. It supports endothelial cell function, promotes vascular wall integrity, and is studied for atherosclerosis prevention, vascular aging, and cardiovascular health maintenance. It is one of the more broadly applicable Khavinson bioregulators given the ubiquity of vascular tissue.
- Half-Life
- Very short (~1–2 hours) in plasma due to protease degradation; topical use bypasses systemic clearance
- Short (minutes); sustained gene-regulatory effects
- Admin Route
- SubQ, Topical, Intranasal
- SubQ, Oral
