What are Selank's primary effects?
Selank is studied for anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) effects. Developed in Russia, it's a synthetic analog of tuftsin. It may help with mood regulation, memory, and immune modulation without the sedative effects of traditional anti-anxiety medications.
How does Selank work?
Selank modulates GABA, serotonin, dopamine, and norepinephrine systems. It influences the expression of brain-derived neurotrophic factor (BDNF) and affects enkephalin metabolism. Unlike benzodiazepines, it doesn't directly bind GABA receptors, so it provides anti-anxiety effects without sedation or dependence risk.
What is tuftsin and how does Selank relate to it?
Tuftsin is a naturally occurring tetrapeptide that stimulates immune function. Selank is tuftsin with an additional glyproline sequence attached (Thr-Lys-Pro-Arg-Pro-Gly-Pro). This modification gives Selank enhanced stability and adds the neurotropic/anxiolytic effects not present in tuftsin alone.
How is Selank administered?
Selank is most commonly administered as a nasal spray for brain-targeted effects. It can also be injected subcutaneously. Typical nasal dosages range from 200-600 mcg per day, often divided into 2-3 doses. Effects are usually felt within 15-30 minutes of intranasal administration.
Does Selank help with anxiety?
Yes, Selank has demonstrated anxiolytic effects in both animal and human studies. It's approved in Russia for anxiety and is comparable to benzodiazepines in effectiveness but without sedation, cognitive impairment, or addiction potential. Users report feeling calmer and more focused without the "drugged" feeling.
Can Selank improve cognitive function?
Research suggests Selank can enhance memory, learning, and mental clarity. It increases BDNF expression, which supports neuroplasticity. Users often report improved focus, better information retention, and clearer thinking. It's sometimes used by students and professionals for cognitive enhancement.
Does Selank have immune effects?
Yes, through its tuftsin component, Selank has immunomodulatory properties. It can enhance immune cell activity and has shown antiviral effects in some studies. This dual action (anxiolytic + immune) makes it unique among anti-anxiety compounds and potentially useful when stress is affecting immune function.
What are the side effects of Selank?
Selank is generally very well-tolerated. Possible side effects include mild nasal irritation (with spray), occasional headache, and fatigue in some users. It does not cause sedation, cognitive impairment, or withdrawal symptoms associated with traditional anxiolytics. Most users report no significant side effects.
How long does reconstituted peptide last?
Once mixed with bacteriostatic water, peptides remain stable for up to 4 weeks when refrigerated at 2-8°C (36-46°F). Unopened powder can last 1+ year in the freezer. Get our complete Storage & Travel Guide.
Is this peptide legal to purchase?
Peptides sold "for research purposes only" are legal to purchase in the US, but are not FDA-approved for human use outside of specific medical applications. Always consult a healthcare provider before use.
