Key Ingredients
A synthetic heptapeptide derived from the naturally occurring immunopeptide tuftsin. Research documents effects on GABA-ergic systems, anxiety-related behavior, and immune regulation.
Discover the researchDescription
Selank is a synthetic heptapeptide analog of the immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro sequence. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences alongside Semax, Selank has been studied for its anxiolytic and cognitive-enhancing properties.
Research Background
Research on Selank has demonstrated effects on GABA receptor expression, monoamine neurotransmitter levels, and BDNF expression in preclinical models. The tuftsin backbone provides immunomodulatory activity, while the Pro-Gly-Pro extension confers enzymatic stability and enhanced CNS activity. For research use only.
Selank is also stocked combined 1:1 with Semax as a single Semax and Selank nasal spray (15mg of each per bottle) for programs that study both heptapeptides.

Frequently Asked Questions
What is Selank nasal spray?
Selank is a synthetic heptapeptide analogue of the immunomodulatory peptide tuftsin. It has been investigated in preclinical models for effects on anxiety-related behaviour, GABAergic signalling, and BDNF expression. This product is a 30mg intranasal solution intended for laboratory research use only.
What is in Stemcode's Selank nasal spray?
Each bottle contains 30mg of Selank total, delivered across 80 sprays. It is third-party lab tested, with results published in its Certificate of Analysis, and ships from within the United States.
What is the difference between Selank and Semax?
Both are Russian-developed synthetic peptides studied as intranasal research compounds, but they derive from different parents: Selank is a tuftsin analogue investigated in anxiety and immunomodulation models, while Semax is an ACTH(4-10) analogue investigated in BDNF and cognition models. Stemcode supplies both for research use only.
Where can I buy Selank nasal spray?
Selank nasal spray is available to order directly from Stemcode for research use. Every batch is lab tested for purity with a published Certificate of Analysis and ships from within the United States.
How should Selank nasal spray be stored?
As a pre-formulated solution, store the nasal spray refrigerated at 2-8°C (36-46°F) and use it within the timeframe indicated on the product label. Keep it away from heat and direct sunlight.
Is Selank nasal spray for human use?
No. Selank and all Stemcode products are sold strictly for in-vitro laboratory and research use only. They are not for human or animal consumption.
