Anxiolytic without sedation · Russian neuropeptide
99% Purity Cognitive Anxiolytic

Selank is a synthetic heptapeptide derived from human tuftsin, developed in Russia. It acts as an anxiolytic without the sedative or addictive effects of benzodiazepines, modulating serotonin, dopamine and the GABA system. It is administered primarily by the intranasal route and has a rapid onset of action (15–30 minutes). Used clinically in Russia for generalized anxiety disorders.

Protocol

Reconstitution & Usage Protocol

Important: Only chill the water for 3 minutes before reconstituting the peptide. Do not prepare with very cold water, because it can freeze, lose effect or become damaged.
1Reconstitution
Materials: 1 vial of Selank 10 mg · 1 vial of bacteriostatic water · insulin syringe or nasal spray bottle · alcohol wipes.
  1. Bring the vial to room temperature for 10–15 minutes.
  2. Disinfect the rubber cap with an alcohol wipe.
  3. Draw up 2 mL of bacteriostatic water (200 IU) or transfer directly into a sterilized nasal spray bottle.
  4. Inject the water slowly down the inner wall of the vial.
  5. Do not shake. Swirl gently until the solution is clear.
Label with the date and refrigerate (2–8 °C). Stable for 28 days.
2Concentration & Dosing
Reconstituting 10 mg in 2 mL → 5 mg/mL = 50 mcg per IU (or per nasal puff, approx.).
Target doseUnitsVolume
250 mcg (low)5 IU / 1 puff0.05 mL
500 mcg (standard)10 IU / 2 puffs0.10 mL
1 mg (high)20 IU / 4 puffs0.20 mL
Universal formula: IU = (dose in mcg ÷ 50)
3Application
Route
Intranasal (preferred) or subcutaneous.
Frequency
1–3 times a day as needed.
Cycle
Continuous or as needed (no addiction). Compatible with Semax.
  • Standard dose: 500 mcg 2–3 times a day during episodes of anxiety or stress.
  • Before applying: let the drawn-up dose lose its chill (only the amount to be injected) — hold the syringe in your hand for 2–3 minutes.
  • After applying: gently massage the area for ~40 seconds to disperse the peptide and improve absorption.
Importante: Solo poner a enfriar el agua 3 minutos antes de reconstituir el péptido. No preparar con agua muy fría, porque se puede congelar, perder efecto o dañarse.
1Reconstitución
Materiales: 1 vial de Selank 10 mg · 1 vial de agua bacteriostática · jeringa de insulina o botella spray nasal · toallitas de alcohol.
  1. Atemperar el vial 10–15 minutos.
  2. Desinfectar la tapa de goma con toallita de alcohol.
  3. Cargar 2 mL de agua bacteriostática (200 UI) o directamente transferir a botella de spray nasal esterilizada.
  4. Inyectar el agua lentamente por la pared interior del vial.
  5. No agitar. Girar suavemente hasta solución transparente.
Etiquetar con fecha y refrigerar (2–8 °C). Estable 28 días.

Frecuencia
1–3 veces al día según necesidad.
Ciclo
Continuo o según necesidad (sin adicción). Compatible con Semax.
  • Dosis estándar: 500 mcg 2–3 veces al día en episodios de ansiedad o estrés.
  • Antes de aplicar: dejar que la dosis cargada pierda el frío (solo la cantidad a inyectar) — sostener la jeringa en la mano 2–3 minutos.
  • Después de aplicar: masaje suave en la zona durante ~40 segundos para dispersar el péptido y mejorar absorción.
Important : Mettre l'eau à refroidir seulement 3 minutes avant de reconstituer le peptide. Ne pas préparer avec de l'eau très froide, car il peut geler, perdre son effet ou s'abîmer.
1Reconstitution
Matériel : 1 flacon de Selank 10 mg · 1 flacon d'eau bactériostatique · seringue à insuline ou flacon spray nasal · lingettes alcoolisées.
  1. Laisser le flacon revenir à température ambiante pendant 10–15 minutes.
  2. Désinfecter le bouchon en caoutchouc avec une lingette alcoolisée.
  3. Prélever 2 mL d'eau bactériostatique (200 UI) ou transférer directement dans un flacon spray nasal stérilisé.
  4. Injecter l'eau lentement le long de la paroi intérieure du flacon.
  5. Ne pas agiter. Tourner doucement jusqu'à obtenir une solution transparente.
Étiqueter avec la date et réfrigérer (2–8 °C). Stable 28 jours.

FAQ

Frequently Asked Questions

What is Selank studied for in research?

Selank is a synthetic heptapeptide derived from human tuftsin, studied as an anxiolytic that modulates serotonin, dopamine and the GABA system without the sedative or addictive effects of benzodiazepines. Research also explores its effects on mental clarity, memory and the stress response. For research use only.

How quickly does Selank act and how is it administered?

In research protocols Selank is administered primarily by the intranasal route (preferred) or subcutaneously, with a rapid reported onset of action of 15–30 minutes. A standard reference dose is 500 mcg taken 2–3 times a day during episodes of anxiety or stress.

How is Selank 10 mg reconstituted and dosed?

Reconstituting 10 mg in 2 mL of bacteriostatic water gives 5 mg/mL, equal to 50 mcg per IU (or per nasal puff). Common reference points: 250 mcg = 5 IU / 1 puff (0.05 mL), 500 mcg = 10 IU / 2 puffs (0.10 mL), and 1 mg = 20 IU / 4 puffs (0.20 mL). The universal formula is IU = (dose in mcg ÷ 50).

How should reconstituted Selank be stored?

After reconstitution, label the vial with the date and refrigerate at 2–8 °C, where it remains stable for 28 days. Only chill the water for 3 minutes before reconstituting — very cold water can freeze the peptide, reduce its effect or damage it.

Semax Cognitive
Semax

Semax is a synthetic heptapeptide derived from the ACTH (4-10) hormone, developed in Russia and approved there for strokes and cognitive disorders. It works by increasing BDNF (neurotrophic factor) and NGF, modulating dopamine and serotonin, and improving neuroplasticity. It is one of the most potent peptide nootropics available, with a rapid effect via the intranasal route.

NAD+ Longevity
NAD+

NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme present in every cell that takes part in more than 500 metabolic reactions, primarily in energy production (ATP) and DNA repair. Its levels decline drastically with age, and exogenous replenishment is associated with improvements in energy, mitochondrial function, cognitive function and longevity markers. It is one of the pillars of modern anti-aging biohacking.

Epithalon Longevity
Epithalon

Epithalon (Epitalon) is a synthetic tetrapeptide developed in Russia from studies with pineal-gland extracts. Its main mechanism is the activation of the enzyme telomerase, which lengthens the telomeres (the protective ends of the chromosomes) and delays cellular senescence. Long-term studies in elderly subjects have shown reduced mortality and improvements in aging biomarkers.
