NA-Semax Amidate vs Epitalon

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 AmidateEpitalon
MechanismMaintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action.Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms.
Typical DosageIntranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax.Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year.
AdministrationIntranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution.Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously.
Side EffectsMay cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated.Generally well-tolerated. May affect sleep patterns initially.
