Selank

A synthetic nootropic peptide approved in Russia for anxiety and cognitive enhancement.

TP-7Selanc

Selank is a synthetic analog of the naturally occurring immunomodulatory peptide tuftsin, developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. It is approved in Russia as an anti-anxiety medication and nootropic. Selank enhances cognitive function, reduces anxiety, and modulates the immune system without the sedation or addiction potential of traditional anxiolytics.

Key Benefits

Anxiety Reduction

Clinical studies show anxiolytic effects comparable to benzodiazepines without sedation, cognitive impairment, or addiction potential.

Cognitive Enhancement

Improves memory formation, learning, and attention through modulation of BDNF expression and serotonin metabolism.

Mood Stabilization

Balances serotonin and norepinephrine metabolism, supporting stable mood without the peaks and troughs of traditional medications.

Immune Support

Retains the immunomodulatory properties of its parent compound tuftsin, enhancing immune cell activity.

Neuroprotection

Research suggests protective effects on neurons through BDNF upregulation and antioxidant mechanisms.

Stress Resilience

Helps normalize stress hormone responses and improves adaptation to psychological and physical stressors.

Research Dosing Information

Common Dose

250-500 mcg per dose

Route

Intranasal spray

Frequency

2-3 times daily

Cycle Length

2-4 weeks, often cycled

Approved as a prescription nasal spray in Russia. Intranasal delivery provides rapid onset (within minutes) through direct absorption. Not available as a prescription in the US or EU.

Research Summary

Selank has been studied in multiple Russian clinical trials for generalized anxiety disorder and cognitive function. Results show significant anxiety reduction (comparable to phenazepam/diazepam) without sedation or withdrawal symptoms. Molecular studies demonstrate effects on GABA, serotonin, dopamine, and norepinephrine systems. Gene expression research shows upregulation of BDNF and modulation of over 50 genes related to neuroplasticity and immune function.

Safety Considerations

Approved as a pharmaceutical in Russia — established safety in clinical use.
Not FDA-approved in the United States.
No addiction potential or withdrawal effects reported.
No significant sedation at recommended doses.
Well-tolerated in clinical trials with minimal side effects.
May affect blood coagulation — caution with anticoagulant medications.

Frequently Asked Questions

Is Selank addictive?

No. Unlike benzodiazepines, Selank does not produce dependence or withdrawal effects. Clinical studies specifically note the absence of addiction potential.

How quickly does Selank work?

Intranasal administration provides effects within minutes. However, full anxiolytic and cognitive benefits typically develop over 1-2 weeks of consistent use.

Can Selank replace my anxiety medication?

Never discontinue prescribed medication without consulting your doctor. While Selank shows anxiolytic effects in clinical research, it is not FDA-approved and should not replace prescribed treatments.
