Heptapeptide · Anxiolytic Research

Selank 5 mg

Selank is a synthetic heptapeptide developed at the Russian Academy of Sciences as the sister compound to Semax. It is the most-studied compound in the Russian anxiolytic-research literature, with published research spanning GABA-pathway modulation, immunomodulation through cytokine expression, and stress-axis interactions. Selank is on the Russian Federation's essential-medicines list for generalised anxiety research.

What Selank is

Selank is the synthetic analogue of tuftsin, an endogenous immunomodulatory tetrapeptide, extended with the prolyl-glycyl-proline tripeptide to improve stability. The full sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro. As with Semax, the C-terminal tripeptide extension is what makes the molecule stable enough for practical research use; the active region is the tuftsin-derived N-terminal portion.

What the research literature covers

Published research on Selank covers anxiolytic studies (GABAergic-pathway modulation in animal stress models), immunomodulation (cytokine expression effects, particularly IL-6 and interferon family), antiviral-research applications (Selank has been studied as an immunomodulatory adjunct in viral-infection models), and broader neuromodulation. Selank is approved in Russia for generalised-anxiety research and has clinical-evidence base from Russian-language literature.

How researchers typically use Selank

Like Semax, the standard route is intranasal — exploiting nose-to-brain transport. Research protocols typically dose 1-3 times daily during active stress-research windows. Researchers studying acute stress-response questions use Selank during the active period; researchers studying immune-modulation questions use longer cycles. Pairing with Semax addresses both cognitive (Semax) and anxiolytic (Selank) axes simultaneously.

Common questions

Is Selank legal in the UAE?
Selank is classified as a research compound in the UAE and is sold through standard wellness-supply channels. It is an approved medicine in the Russian Federation for generalised-anxiety research but is not licensed as a medicine in the UAE. Wellness Labs operates under standard UAE commercial trading rules.
Selank vs benzodiazepines — what is the difference?
Benzodiazepines are direct GABA-A receptor positive allosteric modulators with well-established tolerance and dependence profiles. Selank appears to modulate GABAergic signalling indirectly, through different mechanisms; published research has not reported tolerance or dependence profiles similar to benzodiazepines. The two are mechanistically distinct; researchers studying anxiolytic mechanisms specifically choose Selank to study a non-benzodiazepine pathway.
How is Selank administered?
Intranasal is the standard route — a few drops of reconstituted solution into each nostril. Reconstitution and administration guidance accompanies every shipment.
What is the typical research-protocol dose?
The most-cited dose in the Russian clinical-research literature is 700-1500 mcg per day, split across 2-3 administrations, for cycles of 14-21 days. Research-community protocols vary somewhat below this range. Researchers calibrate to their own protocol design.
Can Selank be used long-term?
Published Russian research has tracked extended-cycle protocols (multiple repeated 21-day courses) without notable tolerance development. Long-term safety data in the Western peer-reviewed literature is limited; researchers studying long-term protocols should design rest periods between active cycles as standard practice.
How quickly does Selank show effects?
Acute anxiolytic effects are reported within the first administration window by researchers in the grey-research community (subjective reports within 30-60 minutes). Cytokine-modulation effects accumulate over 5-14 days of consistent administration.
How is Selank stored?
Lyophilised Selank is ambient-temperature stable in transit. Long-term storage at -20 °C protected from light is recommended. Post-reconstitution refrigerated storage with appropriate handling.
When will Selank be back in stock?
Selank stock status varies. Talk to Nour for current availability and expected restock timing in your delivery region.
