Selank is a synthetic research peptide, developed in Russia as an analogue of the body's own tuftsin. In research it is best known as an anxiolytic and nootropic: it is studied for reducing anxiety and stress and for focus, notably without the drowsiness or addiction risk of classic sedatives. At GradePurity you buy selank as a research-grade peptide: ≥99% HPLC purity and same-day shipping from the Netherlands.
What does selank do?
Selank is best known in research as a "calming" peptide: it is studied for reducing anxiety and stress and for sharper focus. What stands out is that researchers find it interesting precisely because it seems to give this calming effect without drowsiness and without the addiction risk you see with classic sedatives (benzodiazepines). It is thought this is why it is so popular as a nootropic.
How does selank work?
Selank is derived from tuftsin, a small peptide your own body makes that is involved in the immune system. In research, selank acts on the balance of neurotransmitters, including the GABA system (calm) and serotonin and dopamine (mood and motivation). It is thought this combination is why it acts calming in studies without sedating. Most of the research comes from Russia.
Selank vs. semax
Selank and semax are often mentioned together: both are Russian research peptides for the brain, but they do not do the same thing. Selank is a tuftsin analogue and is studied mainly for anxiety and calm. Semax is derived from the hormone ACTH (4-10) and leans more towards focus, alertness and cognition. In anxiety research, selank is usually the first choice; for mental sharpness, semax. See the separately available semax if you want to compare both in research.
Selank dosage
In research, selank is usually used in small doses spread across the day, to keep a calm, even effect rather than one peak. The exact schedules vary by study and are documented in the literature. GradePurity gives no dosing or administration advice itself: we supply selank as a research peptide only, and the details on this page (purity, vial size) are intended for your research documentation.
Side effects of selank
Selank is actually known in research for a mild profile: studies reported few and mild reactions, such as light headache, irritation at the administration site or brief nausea. Large long-term data in humans is still lacking.
Is selank legal?
Selank is an approved medicine for anxiety in Russia, but it is not registered as a medicine in the Netherlands or the EU. You may buy and hold it here as a research-grade peptide for laboratory research. GradePurity supplies it for research only, not for human use.
Purity and lab testing
Every batch of selank is checked in the lab for purity (≥99%) and identity. So you know exactly what you are holding, that is the main difference from anonymous suppliers. The exact specifications are in the table at the bottom of this page.
