Selank: Cognitive / Neuro research guide
In short: Selank is a synthetic tuftsin-derived heptapeptide anxiolytic that allosterically modulates GABAA receptors and upregulates hippocampal BDNF expression. It is studied in preclinical (cell and animal) research and is supplied strictly for laboratory use, not for human or clinical use.

Selank at a glance
What to know first
Details and limits sit in the sections below. Research use only.
What Selank is
Selank is a Russian anxiolytic heptapeptide derived from the immune peptide tuftsin that produces benzodiazepine-like calming effects through GABAA modulation - without sedation, amnesia, or dependence.
One-paragraph overview from our research datasheet. Still scientific, but faster to read than the full mechanism list below.

Common Questions People Are Asking
What is Selank and how does it work?
Selank is a synthetic seven-amino-acid (heptapeptide) derivative of the immune peptide tuftsin, with a Pro-Gly-Pro tail for stability, studied as an anxiolytic and nootropic research compound. The leading mechanistic hypothesis is allosteric modulation of the GABAergic system - it changes the expression of GABA-related genes rather than binding the GABA-A receptor as a direct agonist - alongside effects on monoamine neurotransmitters. New-U supplies it for laboratory research only.
What does the Selank research actually show?
The headline finding is a Russian clinical study where Selank produced anxiolytic effects similar to the benzodiazepine medazepam, plus additional antiasthenic (anti-fatigue) and psychostimulant activity (Zozulya et al., 2008). Mechanistic work shows it modulates GABAergic gene expression (Volkova et al., 2016). These are research findings - mostly from Russian clinical and animal studies - and are not a promise of any effect in humans.
How does Selank compare with benzodiazepines?
A Russian clinical study compared Selank directly with medazepam and found comparable anxiolytic effect. The reported difference is in the side-effect profile: review and clinical literature describe Selank as not producing sedation, amnesia, tolerance, dependence or withdrawal, which are common with benzodiazepines. It is studied as an allosteric GABAergic modulator rather than a direct GABA-A agonist.
How long does Selank take to work, and what is its half-life?
Plasma clearance is rapid - effectively complete within minutes of administration - but the Pro-Gly-Pro tail extends functional activity far beyond the parent tuftsin, whose half-life is measured in seconds. Russian clinical and review sources describe a fast onset for the anxiolytic effect via the intranasal route. We report these figures descriptively from the literature and make no dosing recommendation.
Is Selank legal, and is it FDA-approved?
Selank is not FDA-approved in the United States and is sold strictly as a research chemical for laboratory use, not for human consumption. It is a registered/approved anxiolytic medicine in Russia. Legal status varies by jurisdiction, so confirm your local rules before purchasing.
How does Selank compare with Semax?
Both are Russian heptapeptides with Pro-Gly-Pro stabilising tails and intranasal delivery, and they share several effects such as monoamine modulation. Selank emphasises anxiolysis and stress buffering; Semax (an ACTH(4-10) analogue) emphasises cognition and neuroprotection. They are sometimes studied together in protocols covering both the calm and the focus dimensions.
How should Selank be stored?
Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1-6 °C and protect from light. The Pro-Gly-Pro tail gives Selank much better stability than parent tuftsin (which has a half-life measured in seconds), but standard peptide handling still applies - avoid repeated freeze-thaw cycles.
Is this page medical advice? Can I use Selank for my health?
