Selank is one of the most well-studied anxiolytic and nootropic research peptides. Selank is a

synthetic heptapeptide developed in Russia, modeled after tuftsin, an endogenous

immunomodulatory peptide.

It’s primarily researched for its anti-anxiety, cognitive-enhancing, and immune-supportive properties.

Search results describe it as:

A therapeutic peptide with anxiolytic, nootropic, and immunomodulatory effects

A synthetic peptide with potential to reduce anxiety, boost brain function, and manage stress

A tuftsin analog that modulates GABA and serotonin, increases BDNF, and supports emotional

regulation

How it works:

Reduces anxiety without sedation Enhances memory, learning, and focus

Modulates GABAergic and serotonergic signaling

Increases BDNF expression, supporting neuroplasticity

Supports immune balance via tuftsin-related pathways

Stabilizes stress response and emotional regulation
