LL-37 (Cathelicidin) vs Epitalon
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
LL-37 (Cathelicidin)
LL-37 is the only human cathelicidin antimicrobial peptide. It plays crucial roles in innate immunity and has shown diverse biological activities including antimicrobial, immunomodulatory, and wound healing properties.
Full details →Epitalon
Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.

| Aspect | LL-37 (Cathelicidin) | Epitalon |
|---|---|---|
| Mechanism | Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects. | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. |
| Typical Dosage | Research protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections. | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. |
| Administration | Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols. | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. |
| Side Effects | Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses. | Generally well-tolerated. May affect sleep patterns initially. |
