Epithalamin vs LL-37 (Cathelicidin)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.
Full details →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 →Side-by-Side Comparison
| Aspect | Epithalamin | LL-37 (Cathelicidin) |
|---|---|---|
| Mechanism | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. | Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects. |
| Typical Dosage | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. | Research protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections. |
| Administration | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. | Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols. |
| Side Effects | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. | Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses. |
