Selank
Selank is a synthetic analog of the endogenous immunopeptide tuftsin, delivered as a 10mg (15mL) intranasal preparation under physician supervision. It is understood to relate to calm focus, stress-response signaling, and balanced neuro-immune tone.

Mechanism of action
How Selank works at the receptor, signaling, neural, and regulatory levels — shared to inform, never to promise an outcome. Your physician confirms what is appropriate for you.
Receptor Activation
As a tuftsin analog, Selank is understood to engage tuftsin-related receptor sites linked to immune and microglial cells rather than a single classical neurotransmitter receptor. It appears to modulate GABAergic and serotonergic tone indirectly rather than binding those receptors as a primary agonist. Its calm-focus profile is often attributed to shifting the balance of inhibitory and excitatory signaling without the sedation associated with direct GABA-A binding.
Cell Signaling
Selank is understood to influence enkephalin-degrading enzyme activity, which is linked to slower breakdown of endogenous regulatory peptides. Downstream, it is associated with expression of genes tied to neurotrophic and inflammatory signaling, including BDNF-associated pathways. These intracellular effects are understood to support cellular signaling balance rather than driving a single dominant cascade.
Neural Activity
Selank is understood to be relevant to CNS signaling, with associations to GABAergic, serotonergic, and dopaminergic modulation that may relate to calm, alert states. It is linked to monoamine balance and stress-related neurochemistry without the cognitive dulling seen with conventional sedatives. These connections remain preliminary and are framed around neuromodulation rather than a defined therapeutic neural mechanism.
Regulatory Pathways
Because Selank derives from tuftsin, it is understood to have an immunomodulatory profile, including associations with cytokine balance and innate immune cell activity. It is also understood to be relevant to the stress axis and autonomic tone, where it supports a more regulated response to physiological stressors. These systemic effects are balancing rather than broadly stimulating or suppressive.
