Selank
Threonyl-lysyl-prolyl-arginyl-prolyl-glycyl-proline
Reduce anxiety and enhance mental clarity without sedation.
Selank is a heptapeptide developed in Russia as a synthetic analogue of the human immune peptide tuftsin. It is primarily researched for its potent anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) effects. Unlike traditional anxiety medications, Selank does not cause sedation or cognitive impairment, making it a subject of interest for improving mental function under stress.
Key Benefits
Mechanism of Action
Selank modulates the expression of Interleukin-6 (IL-6) and balances the concentration of monoamine neurotransmitters like serotonin and dopamine. It also rapidly increases the expression of Brain-Derived Neurotrophic Factor (BDNF) in the hippocampus, a key mechanism for its neurogenic and memory-enhancing effects. Its action on the GABAergic system is distinct from benzodiazepines, providing anxiety relief without dependence.
Dosing Guidelines
Typical Dose
300-900 mcg
Frequency
1-3x daily
Duration
10-14 days
Note: Administered as a nasal spray for rapid absorption and direct transport to the brain. Protocols often involve a short 10-14 day course followed by a break of 1-3 weeks before resuming.

Popular Stacking Options
Selank + Semax
Semax and Selank are both Russian nootropic peptides that work on different but complementary pathways. Stacking them provides a broader spectrum of cognitive enhancement, with Semax boosting BDNF and attention, while Selank reduces anxiety and improves mood.

Is Selank a sedative? Will it make me sleepy?
No, one of Selank's key features is its ability to reduce anxiety without causing sedation or drowsiness. Unlike traditional anxiolytics like benzodiazepines, it promotes a calm but alert state of mind, making it suitable for daytime use.
How is Selank different from Semax?
While both are Russian nootropic peptides, they have different primary functions. Selank is primarily anxiolytic (anti-anxiety) with secondary nootropic effects, while Semax is primarily a nootropic (cognitive enhancer) with secondary neuroprotective properties. They are often used together to cover both anxiety and focus.
What's the best way to take Selank, nasal spray or injection?
Nasal spray is the most common and effective method for Selank. This route allows for rapid absorption and direct transport to the brain, maximizing its neurological effects. Subcutaneous injection is an alternative, but the nasal route is generally preferred for its targeted action.
How long does it take to feel the effects of Selank?
The anxiolytic effects can often be felt quite quickly, sometimes within 30 minutes of administration via nasal spray. The cognitive and mood-stabilizing benefits tend to build up over several days of consistent use. A full course is typically 10-14 days.
