LL-37 vs Chonluten
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.
- Chonluten is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific to the bronchi and lungs. While related to Bronchogen (a tetrapeptide), Chonluten is a shorter tripeptide sequence. It supports bronchial mucosal cell function, promotes respiratory epithelial regeneration, and is used in protocols for COPD, chronic bronchitis, and pulmonary anti-aging.
- Half-Life
- Very short (~1–2 hours) in plasma due to protease degradation; topical use bypasses systemic clearance
- Short (minutes for the peptide); sustained gene-regulatory effects
- Admin Route
- SubQ, Topical, Intranasal
- SubQ, Oral
