Side-by-Side Comparison

AspectNA-Semax AmidatePalmitoyl Tetrapeptide-7
MechanismMaintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action.Suppresses interleukin-6 (IL-6) production, reducing inflammation that contributes to skin aging. The anti-inflammatory effect complements collagen-stimulating peptides.
Typical DosageIntranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax.Topical: Usually combined with Palmitoyl Tripeptide-1 at similar concentrations (2-4%) in the Matrixyl 3000 complex.
AdministrationIntranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution.Topical application with other anti-aging actives. The palmitoyl group enhances delivery into the skin.
Side EffectsMay cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated.Excellent tolerability profile. Anti-inflammatory properties may actually soothe sensitive skin.
