Evidence Level

Overview

NA-Semax Amidate (N-Acetyl Semax Amidate) is a modified version of the Russian nootropic peptide Semax, with two chemical modifications: an N-terminal acetyl group and a C-terminal amide group. The short version: people usually care about it for enhanced cognitive version of semax, longer-acting, bdnf stimulation, but the strength of the evidence depends heavily on indication and study type.

NA-Semax Amidate (N-Acetyl Semax Amidate) is a modified version of the Russian nootropic peptide Semax, with two chemical modifications: an N-terminal acetyl group and a C-terminal amide group. These modifications increase the peptide's stability, bioavailability, and duration of action compared to standard Semax.

The acetylation protects against aminopeptidase degradation while the amidation protects against carboxypeptidase degradation, effectively shielding both ends of the peptide from enzymatic breakdown. This results in a longer-acting and more potent version that has become the preferred form in the Western research peptide community.

Known vs uncertain

Known signals

  • 0 registered trials are tracked from ClinicalTrials.gov intervention records.
  • 0 PubMed clinical-trial publications are indexed.
  • 0 PubMed randomized controlled trial publications are indexed.
  • 0 PubMed references are tracked separately from trial counts and can include animal, in-vitro, review, mechanism, or clinical records.

Open questions

  • Evidence strength may vary by indication, route, formulation, and population.
  • Public anecdotes can highlight interest or concern but do not establish clinical efficacy.
  • Regulatory status and compounding access can change independently from the research literature.

Mechanism of Action

Like standard Semax, NA-Semax Amidate is a synthetic analog of ACTH (4-10) that stimulates BDNF (Brain-Derived Neurotrophic Factor) and NGF (Nerve Growth Factor) expression.

Key Research Benefits

Enhanced stability and potency vs standard Semax
Stimulates BDNF and NGF expression
Studied for cognitive enhancement and neuroprotection
Longer duration of action (less frequent dosing)
Modulates multiple neurotransmitter systems simultaneously
