Selank is a synthetic heptapeptide (seven amino acids: Thr-Lys-Pro-Arg-Pro-Gly-Pro) developed at the Institute of Molecular Genetics of the Russian Academy of Sciences — the same institute responsible for Semax. It is derived from tuftsin, a natural peptide produced in the spleen with known immunomodulatory properties, with a Pro-Gly-Pro tail added to extend its half-life and improve stability.
In Russia, Selank is registered as both an anxiolytic drug and an immunomodulatory drug — a dual approval that reflects the two main research directions for this peptide. It is administered nasally in the Russian pharmaceutical market and studied subcutaneously in most Western research contexts.
Selank and Semax are frequently discussed as a complementary pair — developed by the same institute, sharing structural engineering strategies, but targeting opposite ends of the arousal spectrum.
| Compound | Mechanism | Sedation | Dependence Risk | Cognitive Effect |
|---|---|---|---|---|
| Selank | GABA modulation, BDNF | None in research | None observed | Neutral to positive |
| Benzodiazepines | Direct GABA-A agonist | Significant | High | Impairs memory/cognition |
| SSRIs | Serotonin reuptake inhibition | Variable | Low (discontinuation effects) | Variable; often blunting |
| Buspirone | 5-HT1A partial agonist | Minimal | Low | Neutral |
Best current prices for both 5mg ($24.95) and 10mg ($39.95). One of the most consistent Western suppliers for Russian-origin peptides like Selank and Semax.
Visit Swiss Chems →Competitive pricing with reliable US-based fulfillment. 5mg at $29.99 is a strong alternative to Swiss Chems, especially if domestic shipping is preferred.
Visit Spectrum Peptides →Carries Selank alongside a broad catalog. Pricing is mid-range. Good option for combining with other peptide orders to save on shipping.
Visit Behemoth Labz →Research-grade Selank ranges from approximately $3.99/mg (Swiss Chems 10mg) to $30/mg (Peptide Lab) in 2026. Swiss Chems and Spectrum Peptides offer the best value. Selank is notably cheaper per mg than its partner peptide Semax ($20–$30/mg), making it accessible for research protocols that combine both.
Selank is registered as an anxiolytic drug in Russia, but it is sold in Western markets strictly as a research chemical for laboratory use — not as a drug or supplement. Research in animal models and Russian clinical studies has characterized it as anxiolytic without sedation or dependence risk. It should not be compared directly to prescription anxiolytics for personal use purposes.
Selank is typically administered either intranasally (as a nasal spray, which is the pharmaceutical form used in Russia) or subcutaneously (as a reconstituted injection, which is more common in Western research contexts). Like all lyophilized peptides, the powder must be reconstituted with bacteriostatic water before subcutaneous use. When searching supplier websites, only record powder/vial prices — nasal spray preparations are a different product.
Selank's synthesis is somewhat simpler than Semax's, and it has been available in the Western research peptide market longer, creating more supplier competition. Semax is a heptapeptide with a more complex sequence and harder-to-source starting materials. Both are relatively niche compared to mainstream research peptides like BPC-157 or semaglutide, but Selank benefits from slightly higher supply-side competition keeping its price lower.
Selank does not appear on the WADA (World Anti-Doping Agency) prohibited substances list. It is not classified as a growth hormone secretagogue, stimulant, or banned peptide hormone. Competitive athletes are not prohibited from using it under most sporting regulations, though individual sport governing bodies may have separate rules. Always verify with your specific governing body.
