Selank reconstitution calculator.
Selank shares Semax's profile: 10 mg to 30 mg vials, mostly intranasal, and targets in the hundreds of micrograms. The same concentration reads as drops or as syringe units depending on how you use it.
Reference range often cited for Selank: 200–400 mcg, shown for orientation only, not a recommendation. Enter your own target below. Read the evidence →
Each unit on a 100u · 1.0 mL syringe ≈ 50 mcg of this solution.
Show the math
More water → lower concentration → more units for the same amount.
What changes the math for Selank.
- 10 mg in 2 mL is 5,000 mcg/mL, so 300 mcg is 6 units, or roughly 0.06 mL if you are counting drops.
- Larger 30 mg vials triple the concentration at the same water volume, so a table written for a 10 mg vial reads three times too high.
- Selank and Semax are frequently used together but are separate vials at separate concentrations, so unit counts never carry across.

Selank: research formats
Choose the format you are researching to see route-specific notes.
Standard format. Selank is a registered nasal spray in Russia (0.15% solution).
Selank is commercially registered in Russia as a 0.15% nasal spray (1.5 mg/mL). The intranasal route offers efficient absorption via the olfactory mucosa. Research contexts outside Russia use reconstituted lyophilized powder in preserved water, typically at 1.5–5 mg/mL.
0.15% = 1.5 mg/mL. One standard nasal drop (0.03–0.05 mL) delivers approximately 45–75 mcg of Selank at the registered 0.15% concentration.
Selank is more anxiolytic than cognitive-enhancing; the intranasal route produces effects within 15–30 minutes in most research reports.
FAQ.
How many units is 300 mcg of Selank?
On 10 mg in 2 mL (5,000 mcg/mL) it is 6 units. On a 30 mg vial in the same 2 mL (15,000 mcg/mL) it is 2 units, which is small enough to be worth diluting further.
Can I prepare Selank as a nasal spray?
The concentration arithmetic is the same. What differs is the delivery volume of your specific sprayer or dropper, which the calculator cannot know, so it gives you the volume and you divide by yours.
What does the evidence say about Selank?
Mostly single-group Russian literature, which the compound profile flags explicitly rather than counting as replication. That is an evidence question, separate from this arithmetic.
This page is arithmetic on numbers you enter. It does not recommend an amount of Selank, and nothing here is medical advice. For what the published evidence actually supports, read the Selank profile, and for regulatory status see is Selank legal. Reviewed June 1, 2026.
