Over Selank
Selank is a synthetic heptapeptide analog of the naturally occurring immunomodulatory peptide tuftsin, developed by the Russian Academy of Sciences and approved in Russia for anxiety and cognitive enhancement. Its mechanism — modulating GABAergic signaling without benzodiazepine-like sedation or dependency — has made it one of the most studied anxiolytic peptides in the world. Researchers value Selank for its clean anxiolytic profile with simultaneous nootropic effects.

Researchers value Selank for its clean anxiolytic profile with simultaneous nootropic effects.
Selank is a synthetic heptapeptide analog of tuftsin (Thr-Lys-Pro-Arg), the immunomodulatory fragment of IgG heavy chain, extended with Pro-Gly-Pro at the C-terminus for metabolic stability. Developed at the V.V. Zakusov Research Institute of Pharmacology (Russia). Its anxiolytic mechanism involves concentration-dependent allosteric modulation of GABA-A receptors (comparable to benzodiazepines), modulation of GABAergic gene expression (GABA transaminase, GAD, GABA-A receptor subunits), enhancement of enkephalin-degrading enzyme activity, and immunomodulatory effects via tuftsin-like NK cell and phagocyte activation.
Duidelijkheid van het mechanisme: Well-characterized (GABA-A allosteric modulation, GABAergic gene expression, enkephalin metabolism)

Bewijsniveau: Emerging
Emerging — Approved in Russia with clinical data for GAD. Mechanism well-characterized in peer-reviewed journals. Limited Western clinical trial data. The GABA-A modulation mechanism is well-understood and comparable to established anxiolytic pathways.

Opslag en hantering
Gevriesdroogd poeder: Room temp or refrigerated
Na reconstitutie: Refrigerate at 2-8°C, use within 14-21 days
Reconstitutiestappen uit de dataset
- Prepare. If using pre-made nasal spray, skip to step 5. For powder reconstitution: clean vial top with alcohol.
- Add saline. Draw 2mL bacteriostatic saline (NOT water) and inject slowly into vial.
- Dissolve. Gently swirl until fully dissolved. Solution should be clear.
- Transfer. Transfer solution to a sterile nasal spray bottle. Each spray ≈ 0.1mL (200mcg at 5mg/mL).
- Administer. Insert nozzle into nostril and spray. Alternate nostrils. Standard dose: 1-3 sprays (200-600mcg) 2-3x daily. Can also use 1-2 sprays as needed for acute anxiety.
- Store. Refrigerate nasal spray. Use within 14-21 days after reconstitution.
Veiligheid en beperkingen
Onderzocht voor: Generalized anxiety disorder, Neurasthenia, Immune modulation, Cognitive enhancement, Stress resilience
Gemelde aanvang: 10-20 minutes intranasal; can be used acutely for situational anxiety
Gemelde duur: 2-4 week cycles on, 2 weeks off; also used as-needed for acute anxiety
Meldingen uit de community: More consistently positive than Semax. Users describe "calm focus without sedation." No reports of dependence or withdrawal — a major selling point vs benzodiazepines. N-Acetyl Selank reported as notably more potent. Nasal spray format slightly inconvenient but manageable.

Vragen over Selank
Vragen en antwoorden die bij dit product zijn vastgelegd.
Both Selank and benzodiazepines modulate GABA-A receptors, but through different allosteric sites. Selank also modulates expression of 45+ GABAergic genes (transporter, synthesis, receptor subunits), providing a broader, more physiological regulation. Critically, Selank shows no evidence of tolerance, dependence, or withdrawal syndrome — the major limitations of benzodiazepines.
Yes. Semax and Selank are frequently studied together as complementary nootropics — Semax for focus/energy, Selank for calm/anxiety reduction.
Research indicates Selank does not produce tolerance, dependence, or withdrawal effects — unlike benzodiazepines.
