Leuphasyl vs Lactoferricin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Leuphasyl
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.
Full details →Lactoferricin
Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.

| Aspect | Leuphasyl | Lactoferricin |
|---|---|---|
| Mechanism | Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity. | Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. |
| Typical Dosage | Topical: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides. | Research applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. |
| Administration | Topical application to expression lines. Best results with consistent twice-daily use over 8+ weeks. | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. |
| Side Effects | Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations. | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. |
