LL-37 vs Thymalin
An educational, source-based comparison of LL-37 and Thymalin — 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 polypeptide complex extracted from calf thymus, studied as an immune bioregulator. Research suggests restoration of T-cell function and thymic activity in aged and immunocompromised cohorts.
- Immunosenescence
- Recovery from infection in elderly cohorts
- Adjunct in chronic inflammatory conditions
- • Approved in Russia; not FDA-approved.
- • Mixture composition is not fully characterized.
