How many units of NA-Selank Amidate should I draw?

It depends on your vial size, BAC water, and dose. For a 5mg vial with 0mL BAC water, a beginner dose of 200mcg is typically 0 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to NA-Selank Amidate?

The standard amount is 0mL of bacteriostatic water for a 5mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a NA-Selank Amidate vial last?

At a beginner dose of 200mcg 2x daily, a 5mg vial lasts about 25 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for NA-Selank Amidate?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

NA-Selank Amidate Pharmacokinetics

Pharmacokinetics — Active Dose Over Time

t½ = ~2-3 min (plasma); functional effects persist 6-8 hours via downstream gene expression

After 1 half-life (7h): 50% remainsAfter 2 half-lives (14h): 25% remainsAfter 3 half-lives (21h): 12.5% remains

At a 400mcg dose: 50% = 200mcg remaining after 7h. Recommended frequency: 2x Daily.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

NA-Selank Amidate Dosing Protocol

Level	Dose / Injection	Frequency
Beginner	200mcg	2x Daily
Moderate	400mcg	2x Daily
Aggressive	600mcg	3x Daily

Note: N-acetylated, C-amidated analog of Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro). The acetyl and amide modifications improve enzymatic stability and nasal membrane permeability compared to native Selank. Administered intranasally as a pre-mixed nasal spray — no reconstitution needed. Approved in Russia as an anxiolytic for GAD and neurasthenia under the parent Selank formulation.

About NA-Selank Amidate

NA-Selank Amidate is a stabilized derivative of Selank, itself a synthetic heptapeptide analog of the endogenous immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg). The N-terminal acetylation and C-terminal amidation modifications protect the peptide from rapid degradation by aminopeptidases and carboxypeptidases, extending its functional half-life after intranasal delivery. NA-Selank Amidate acts through multiple converging mechanisms: positive allosteric modulation of GABA-A receptors (producing anxiolytic effects comparable to low-dose benzodiazepines without sedation or dependence), inhibition of enkephalin-degrading enzymes (raising endogenous enkephalin levels), upregulation of BDNF expression in the hippocampus, and modulation of pro-inflammatory cytokines including IL-6, IL-1-beta, and TNF-alpha. Clinical trials of the parent compound Selank in patients with generalized anxiety disorder demonstrated efficacy comparable to medazepam, with additional antiasthenic and mild nootropic properties not seen with benzodiazepine comparators.
