Side-by-Side Comparison

AspectLactoferricinMelanotan I
MechanismBinds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects.Binds to melanocortin 1 receptors (MC1R) on melanocytes, stimulating eumelanin production. This increases skin pigmentation and provides photoprotection without UV exposure.
Typical DosageResearch applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily.Clinical: 16mg implant every 2 months. Research protocols for tanning typically use 0.5-1mg daily for loading, then maintenance dosing.
AdministrationAvailable through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings.FDA-approved form is a subcutaneous implant. Research use involves subcutaneous injection. Often combined with minimal UV exposure to enhance results.
Side EffectsLactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies.Nausea (especially initially), facial flushing, fatigue, headache, and darkening of existing moles or freckles.
