Selank is a synthetic peptide investigated chiefly in the fields of cognition and emotional regulation, and it is frequently mentioned in the same breath as Semax. This guide outlines what Selank is, where it came from and what researchers have examined so far.
Key points
- Selank is a synthetic analogue of tuftsin, a naturally occurring peptide.
- It was developed through Russian research programmes.
- Studies have looked at anxiolytic activity, attention, memory and neurotransmitter systems.
- Most of the evidence is still early-stage.
What is Selank?
Selank is a laboratory-made peptide modelled on tuftsin, a small natural molecule. It originated in Russian research and has mainly been studied in relation to anxiety (anxiolytic effects in research models) and cognitive function.
What does the research examine?
Investigations involving Selank have covered emotional regulation, attention and memory, as well as its interaction with neurotransmitter systems. It is regarded as an interesting subject within nootropic research, the study of compounds that may influence cognition, but the body of data remains limited and largely preliminary.
Why is Selank studied alongside Semax?
Selank and Semax are both products of the same Russian school of cognitive peptide research, so they are often discussed and examined together. Despite that shared background, they are thought to work through different mechanisms.
Handling in the laboratory
Selank is supplied as a lyophilised powder and is reconstituted for laboratory work with bacteriostatic water. Our reconstitution calculator can assist with concentration calculations.
Frequently asked questions
What is the difference between Selank and Semax?
Both are studied as nootropics, but Selank research leans towards emotional regulation and Semax research towards cognition. Our guide What is Semax? covers the latter in more detail.
