NA-Semax Amidate vs Lactoferricin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

NA-Semax Amidate

NA-Semax Amidate (N-Acetyl Semax Amidate) is a modified version of Semax with enhanced stability and potency. Also known as NASA, it provides stronger and longer-lasting nootropic effects than standard Semax.

Side-by-Side Comparison

AspectNA-Semax AmidateLactoferricin
MechanismMaintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action.Binds to and disrupts microbial membranes through electrostatic interactions. Also binds to lipopolysaccharide (LPS) to neutralize endotoxins and has immunomodulatory effects.
Typical DosageIntranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax.Research applications vary widely. Oral lactoferrin supplements (containing lactoferricin precursor) typically dosed at 100-400mg daily.
AdministrationIntranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution.Available through lactoferrin supplementation orally. Purified lactoferricin primarily used in research settings.
Side EffectsMay cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated.Lactoferrin supplementation is generally well-tolerated. May cause GI upset in some individuals. Derived from milk so caution with dairy allergies.
