What Is Selank?
Category: Peptide
A synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin. Researched for anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) properties.
Detailed Explanation
Selank is a synthetic heptapeptide (7 amino acids) developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is derived from tuftsin, a naturally occurring tetrapeptide involved in immune regulation, with additional amino acids added to improve stability and bioavailability. Selank has been researched for its anxiolytic (anti-anxiety), nootropic (cognitive-enhancing), and immunomodulatory properties, and is approved as an anti-anxiety medication in Russia.
Practical Context
Selank is commonly administered intranasally (as nasal drops) at doses of 250-500mcg, 2-3 times daily, though subcutaneous injection is also used. It can be combined with Semax, another nootropic peptide, for complementary cognitive effects. Unlike benzodiazepines, Selank does not cause sedation, cognitive impairment, or dependence. Effects are typically noticed within 15-30 minutes of administration and last several hours.
Frequently Asked Questions
How does Selank compare to Semax?
Selank is more focused on anxiolytic (anti-anxiety) effects, while Semax is more focused on cognitive enhancement and neuroprotection. They work through different mechanisms and are often combined.

Related Terms
- Bioavailability - The proportion of a substance that enters the bloodstream and is available to produce an active effect. Subcutaneous injection provides near-complete bioavailability for most peptides.
- Half-Life - The time it takes for half of a substance to be eliminated from the body. Determines dosing frequency - shorter half-life peptides need more frequent dosing.
