Semax 5mg Nasal Spray – 50mcg/Spray

Semax is a synthetic heptapeptide analogue of the ACTH(4-7) fragment; a sequence derived from adrenocorticotropic hormone. Developed by the Institute of Molecular Genetics of the Russian Academy of Sciences, the same institution responsible for Selank. Hudson Science’s formulation delivers 5mg total Semax at 50mcg per metered spray in a nasal delivery system; the standard and most clinically referenced administration route for Semax, where intranasal delivery has been the primary format studied in Russian medical research since the compound’s original development and subsequent approval as a nootropic and neuroprotective agent in Russia and Ukraine.

Semax’s primary research mechanism centres on its documented upregulation of brain derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expression; neurotrophins that support neuronal survival, synaptic plasticity, and the formation of new neural connections. This neurotrophin upregulation mechanism distinguishes Semax from classical stimulant nootropics that operate through monoamine pathway modulation, positioning it instead as a compound of research interest in neuroplasticity, memory consolidation, and neuroprotection studies. Semax also carries documented influence on the dopaminergic and serotonergic systems, contributing a broader neuromodulator research profile that has supported investigation across cognitive enhancement, stress response, and mood regulation pathways.

Semax and Selank represent complementary research subjects within CSD’s nootropic nasal spray range despite their shared Russian Academy of Sciences origin. Where Selank’s primary documented activity centers on anxiolytic and GABAergic modulation alongside its Tuftsin derived immunomodulatory characteristics, Semax’s research profile is more specifically focused on neurotrophin upregulation, cognitive enhancement, and neuroprotective activity. The two compounds operating through distinct primary mechanisms that make them frequently studied in comparative nootropic peptide research. CSD stocks both in matched 5mg nasal spray presentations at 50mcg per spray, allowing direct comparative research from a single verified Canadian supplier.
