Semax – 5mg

Semax is a synthetic heptapeptide analogue of the ACTH(4-7) fragment developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. The same institution responsible for Selank, with regulatory approval as a nootropic and neuroprotective agent in Russia and Ukraine, contributing a documented clinical research history that distinguishes it from most synthetic nootropic peptides. Hudson Science’s 5mg lyophilized vial delivers a lower concentration presentation than the Hudson Science 5mg nasal spray at equivalent total compound, with the lyophilized injectable vial format serving distinct research purposes from the intranasal delivery system despite matching concentration.

The 5mg injectable vial and 5mg nasal spray occupy the same concentration point in CSD’s Semax range through fundamentally different administration routes. The nasal spray format is the primary clinically referenced administration route for Semax, intranasal delivery has been the standard format studied in Russian medical research since the compound’s development, with the olfactory epithelium proximity providing potential direct CNS access via the olfactory nerve pathway that is particularly relevant for Semax’s hypothalamic and cortical neurotrophin targets. The lyophilized vial’s reconstitute format supports parenteral administration research, in vitro neuronal cell culture applications, and comparative bioavailability studies examining intranasal versus injectable Semax delivery. Research designs where matched concentration across both formats makes direct route comparison particularly practical from a single verified Canadian supplier.

Semax’s BDNF and NGF neurotrophin upregulation mechanism, stimulating the production of neurotrophins that support neuronal survival, synaptic plasticity, and new neural connection formation. Distinguishes it from classical stimulant nootropics operating through monoamine pathway modulation and from Selank’s primarily anxiolytic GABAergic mechanism. This neurotrophin centered neuroprotective profile has generated research investigation across cognitive enhancement, stroke recovery, attention modulation, and neurodegenerative disease models. Research applications supported by the compound’s Russian clinical approval history and several decades of documented investigation.

Hudson Science formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks Semax across two formats: this 5mg lyophilized vial and the 5mg nasal spray, alongside the closely related Selank across three formats, giving researchers complete nootropic neuropeptide delivery route and concentration flexibility from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.

Reconstitute with bacteriostatic water prior to use. Store lyophilized peptide at 2–8°C away from direct light. Once reconstituted refrigerate and use within 28 days. Intended for research purposes only.
