LL-37 vs Thymogen
An educational, source-based comparison of LL-37 and Thymogen — how each peptide works, what it's researched for, and what to know before going deeper.
Human cathelicidin peptide with antimicrobial and immune-modulating activity.
The only human cathelicidin antimicrobial peptide. Research demonstrates broad antimicrobial activity against bacteria, viruses, and fungi, plus immunomodulatory effects on neutrophils, macrophages, and wound healing.
- Chronic biofilm infections
- Wound healing and dermatology
- Innate immune modulation
- • Not FDA-approved.
- • Pro-inflammatory effects possible at higher doses.
A synthetic dipeptide (Glu-Trp) in the Khavinson bioregulator family. Research suggests modulation of thymic and immune cell gene expression, supporting T-cell maturation and innate immune response in aged models.
- Immunosenescence and age-related immune decline
- Post-infectious immune recovery
- Chronic fatigue and immune dysregulation
- • Russian bioregulator research; limited independent replication.
- • Not FDA-approved.
