NA SELANK: N-Acetyl Selank Amidate (10mg)

What Is Selank? (Background)

Selank is a synthetic heptapeptide derived from tuftsin, a naturally occurring immunomodulatory peptide fragment. It was developed in Russia in the 1990s as a next-generation anxiolytic and neuroregulatory compound.

Unlike traditional anti-anxiety medications (such as benzodiazepines or SSRIs), Selank does not cause sedation, dependence, or cognitive impairment. Instead, it was engineered to support emotional balance, stress resilience, and cognitive stability while preserving mental clarity.

Selank readily crosses the blood–brain barrier, allowing it to act directly on central nervous system signaling pathways.

What Does Selank Do?

Selank is best known for its anxiolytic and mood-stabilizing effects, while also supporting cognitive performance. It has been studied for its ability to:

• Reduce anxiety and emotional tension

• Support calm focus and mental composure

• Improve stress tolerance without sedation

• Enhance cognitive performance under stress

Clinically, Selank has been used in Russia for conditions involving anxiety disorders, stress-related cognitive impairment, neurasthenia, and ADHD.

How Does Selank Function in the Body?

Selank exerts its effects through several complementary mechanisms:

1. GABAergic Modulation
Selank enhances GABA receptor signaling, the brain’s primary inhibitory neurotransmitter system, helping to:

• Reduce excessive neuronal firing

• Promote calmness and emotional stability

• Lower anxiety without impairing cognition

2. Neurotransmitter Regulation
Selank influences key neurotransmitters, including:

• Serotonin – supporting mood balance and emotional regulation

• Dopamine – helping maintain motivation and cognitive engagement

3. Stress Axis Regulation

Selank helps normalize activity within the hypothalamic–pituitary–adrenal (HPA) axis, supporting healthier responses to psychological and physiological stress without suppressing normal cortisol rhythms.

4. Neuroimmune Effects
Derived from tuftsin, Selank also exhibits immunomodulatory properties, suggesting a link between stress regulation and immune balance.

What Do Studies Show?

Research from Russian and Eastern European clinical settings indicates that Selank:

• Reduces anxiety levels comparable to benzodiazepines, without sedation or dependency

• Improves attention, working memory, and mental performance under stress

• Supports emotional stability in patients with anxiety-related cognitive dysfunction

• Demonstrates a strong safety and tolerability profile

Most studies utilized intranasal administration, allowing for direct nose-to-brain delivery and rapid central nervous system effects.

Overall Benefits of Selank

• Reduces anxiety and emotional tension without sedation

• Promotes calm focus and stress resilience

• Supports mood balance and emotional regulation

• Enhances cognitive performance under pressure

• Does not impair memory, reaction time, or alertness

Selank is frequently stacked with Semax to create a balanced nootropic profile — pairing cognitive enhancement (Semax) with emotional regulation and calm focus (Selank).
