Selank 7.5 mg/mL 4 mL Vial Nasal Spray

Selank 7.5 mg/mL – 4 mL Vial Nasal Spray is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the endogenous immunomodulatory peptide tuftsin. It is primarily used in research and investigational settings for its anxiolytic, neuroprotective, and cognitive-enhancing properties. Selank modulates GABAergic and serotonergic neurotransmission, promoting inhibitory signaling in the brain to reduce anxiety without sedative effects. It also appears to upregulate brain-derived neurotrophic factor (BDNF), supporting synaptic plasticity, memory formation, and neuronal survival. The intranasal route allows rapid absorption through the nasal mucosa, facilitating direct central nervous system access while avoiding first-pass metabolism. At 7.5 mg/mL in a 4 mL vial, the total content is 30 mg of Selank. It is typically administered as a nasal spray in controlled research or clinical study protocols. Experimental studies suggest Selank may improve attention, learning, memory, and emotional regulation in preclinical and early clinical models.
