Lactoferricin vs Thymulin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →Thymulin
Thymulin (Facteur Thymique Sérique) is a zinc-dependent nonapeptide hormone produced by thymic epithelial cells. It plays important roles in T-cell differentiation and immune system maturation.

| Aspect | Lactoferricin | Thymulin |
|---|---|---|
| Mechanism | Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects. | Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age. |
| Typical Dosage | Research applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily. | Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range. |
| Administration | Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings. | Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity. |
| Side Effects | Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies. | Limited data on exogenous administration. Theoretical effects on immune function require monitoring. |
