Type
NA-Selank Amidate is an enhanced version of Selank, the anxiolytic nootropic peptide developed at Russia's Institute of Molecular Genetics. The N-acetyl group improves blood-brain barrier penetration and creates more stable metabolites, while the C-terminal amidation further enhances metabolic stability and receptor binding. Unlike benzodiazepines, it provides anxiety relief without sedation, dependency, or cognitive impairment.

Overview of NA-Selank Amidate
NA-Selank Amidate modulates multiple neurotransmitter systems including GABA, dopamine, and serotonin, while regulating brain-derived neurotrophic factor (BDNF). It allosterically modulates GABAA receptors without causing the sedation or dependency of benzodiazepines. The peptide activates serotonin metabolism in the hypothalamus and brainstem, and increases BDNF levels to promote neuronal growth and differentiation.
anxiety and mood
- Standard Selank approved in Russia for GAD; NA-Selank Amidate offers enhanced delivery.
- Modulates stress response through GABA and serotonin systems without sedation.
- Improves mood through serotonin metabolism activation.
cognitive enhancement
- Increases memory trace stability for up to 30 days in animal studies.
- BDNF elevation supports learning and neuroplasticity.
- BDNF increase reduces effects of neurological injury.
immune support
- Based on tuftsin structure, retains immunomodulatory properties.

PeptideNA-Selank Amidate Protocols
Intranasal spray is the preferred delivery method, providing direct access to the brain while bypassing first-pass metabolism. The N-acetyl and amide modifications enhance absorption and stability.
| Goal | Dosage | Frequency | Route |
|---|---|---|---|
| Anxiety relief | 250 | 1 week range | Intranasal |
| Cognitive enhancement | 200 | 1 week range | Intranasal |
| Standard protocol | 300 | 1 week range | Intranasal |
NA-Selank Amidate Cycle
The NA-Selank Amidate Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.

Reconstitution Tips
- Use bacteriostatic water (BAC) — contains 0.9% benzyl alcohol for preservation
- Inject water slowly — aim down the vial wall, not directly onto powder
- Never shake — gently swirl or roll the vial until dissolved
- Store properly — refrigerate at 2-8°C after reconstitution
- Use within 28 days — most reconstituted peptides remain stable for about 4 weeks
- Keep sterile — always clean vial tops with alcohol before drawing

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
