Side-by-Side Comparison

AspectLactoferricinMelanotan II
MechanismBinds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects.Non-selective melanocortin receptor agonist affecting MC1R (tanning), MC3R and MC4R (sexual function and appetite). This broader activity explains its multiple effects beyond tanning.
Typical DosageResearch applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily.Typical protocols: 0.25-0.5mg daily during loading phase for 1-2 weeks, then 0.5-1mg before UV exposure for maintenance. Start low to assess tolerance.
AdministrationAvailable through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings.Subcutaneous injection. Usually combined with UV exposure for tanning effects. Nasal spray formulations exist but have lower bioavailability.
Side EffectsLactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies.Nausea (common initially), facial flushing, spontaneous erections, increased libido, appetite suppression, and mole darkening.
