What is NA Semax Amidate 30MG

NA Semax Amidate 30MG is a chemically stabilized version of the synthetic heptapeptide Semax, studied in research for its potent nootropic, neuroprotective, and cognitive-enhancing effects. It is intended exclusively for research use.

Regarding its chemical identity, NA has a molecular formula of C39H60N10O10 (Base Semax) and a molecular weight of 813.0 (Base Semax) g/mol. Its reported canonical sequence is Met-Glu-His-Phe-Pro-Gly-Pro (N-Acetyl, C-Amidated). A confirmed CAS number is not available in open primary reference sources and is therefore omitted.

Its synonyms include NA.

Mechanism of action of NA

NA Semax Amidate rapidly stimulates the expression of Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF) in the hippocampus and forebrain. It also modulates dopaminergic and serotonergic receptors, enhancing attention, memory formation, and mental endurance under extreme stress.

Pharmacokinetics and pharmacodynamics of NA

The N-Acetyl and C-Amidated modifications protect the ends of the peptide chain, preventing rapid breakdown in the bloodstream or nasal mucosa. This results in a massive increase in blood-brain barrier penetration and a sustained neurotrophic effect compared to standard Semax.

Scientific evidence on NA

The available evidence on NA is preliminary and largely inconclusive, and should be interpreted with caution. The literature describes it as having been investigated for multiple indications in preclinical models.

Base Semax is widely used in Russia for stroke recovery and cognitive decline. The NA-Amidate version, used exclusively in research, shows profoundly enhanced efficacy in animal models of cognitive deficit, ischemic damage, and heavy metal neurotoxicity.

NA applications in research

Ideal for (research context):
– In vitro and preclinical studies of its specific receptor pathways.
– Investigation of tissue repair, cell proliferation, and functional restoration in laboratory models.
– Comparative work with related peptides.

Not applicable for:
– clinical, diagnostic or therapeutic use.
– Any administration to humans or animals outside of an authorized research protocol.

NA protocols in preclinical studies

The literature consulted does not include numerical doses from studies that can be cited for NA, so no trial schemes or quantities are specified.

The presentations of this product (30MG) refer only to the amount of lyophilized peptide per vial (or volume for liquids) and do not constitute a dosage recommendation. The design of any protocol, including concentrations and working volumes, is the responsibility of the researcher, based on their experimental objectives and the relevant primary literature.

Reconstitution and manipulation of NA

As a general guideline for laboratory handling, lyophilized peptides such as NA are usually reconstituted with bacteriostatic water (sterile water with approximately 0.9% benzyl alcohol).

Add the solvent slowly down the side of the vial, letting it run over the lyophilized powder; avoid injecting the stream directly onto the powder.
Do not shake: gently rotate the vial until completely dissolved.
Adjust the solvent volume according to the desired working concentration, considering the 30MG contents of the vial.

These guidelines are for general technique and do not replace the internal procedures of each laboratory.

NA Stability and Storage

As a standard laboratory handling procedure for peptides:

Freeze-dried (unreconstituted): This is the most stable form. It is best preserved by freezing and protecting it from moisture and light for long-term storage.
Reconstituted: once in solution, the peptide is less stable and must be kept refrigerated, being used within a short period; for extended storage, freezing in aliquots is usually preferred.
Avoid repeated freeze-thaw cycles, as they can degrade the peptide.

Given that the molecule is characterized by rapid enzymatic degradation in biological media, careful cold chain management is especially relevant.

Documented NA security profile

The documented safety information in open sources for NA is limited and should be interpreted with caution, also considering that it is research material and not for clinical use.

Theoretical risks include overstimulation, insomnia, or irritability due to elevated dopamine and BDNF levels if dosed excessively. It does not carry the cardiovascular risks of amphetamine-based stimulants.

Formal contraindications and adverse event rates are not available in the consulted literature, so no figures are reported.

NA in a comparative context

Compared to base Semax, it is substantially more potent and longer-lasting. Compared to NA Selank Amidate, NA Semax Amidate is a powerful stimulant and cognitive enhancer, while Selank is calming and anxiolytic.

History and development of NA

Semax was originally developed by the Institute of Molecular Genetics at the Russian Academy of Sciences. The NA-Amidate modification was later popularized by the Western research chemical community to maximize the peptide’s stability for systemic and intranasal administration.
