Selank Dosing Calculator & Reconstitution Guide
A synthetic peptide researched for anxiety and cognition.
Selank is a research peptide. A synthetic peptide researched for anxiety and cognition. To dose it, reconstitute the vial (for example 5 mg in 2 mL of bacteriostatic water for 2.5 mg/mL), then divide your target dose by that concentration to find the units to draw.

What is Selank?
Selank is a synthetic analog of the immunomodulatory peptide tuftsin, studied for anti-anxiety, mood, and cognitive effects. Research doses are typically expressed in micrograms and dosed daily, sometimes intranasally. Also known as TP-7.
How many units is each Selank dose?
| Dose | Volume to draw | Units (U-100) |
|---|---|---|
| 250 mcg | 0.1 mL | 10 units |
| 500 mcg | 0.2 mL | 20 units |
Based on a 5 mg vial reconstituted with 2 mL of bacteriostatic water (2.5 mg/mL) and a U-100 insulin syringe. The dose amounts shown are commonly reported by the community and in anecdotal research, not recommendations or medical advice; only the reconstitution math (volume and units) is calculated for you.
How to calculate a Selank dose
- 1
Choose your vial and water
Select your Selank vial size (for example 5 mg) and the volume of bacteriostatic water you will add (for example 2 mL).
- 2
Find the concentration
Divide vial milligrams by water volume. 5 mg in 2 mL gives 2.5 mg/mL.
- 3
Calculate the draw
Divide your target dose by the concentration to get the volume in mL, then multiply by 100 to get units on a U-100 insulin syringe.
- 4
Verify on the syringe
Use the Keel calculator to see the exact draw rendered on a to-scale syringe, with a warning if the dose exceeds the syringe capacity.
Selank dosing FAQ
How do I reconstitute Selank?
A common approach is to add 2 mL of bacteriostatic water to a 5 mg vial, which gives 2.5 mg/mL. Add the water slowly down the vial wall, swirl gently rather than shaking, and let the powder dissolve fully before drawing.
How many units is 250 mcg of Selank?
At 2.5 mg/mL, 250 mcg equals 0.1 mL, which is 10 units on a U-100 insulin syringe.
What Selank doses do people report?
Community and anecdotal reports commonly cite 250 to 500 mcg. These are figures people report, not a recommendation from Keel. Selank is a synthetic analog of the immunomodulatory peptide tuftsin, studied for anti-anxiety, mood, and cognitive effects. Research doses are typically expressed in micrograms and dosed daily, sometimes intranasally.
Which insulin syringe should I use for Selank?
A U-100 insulin syringe is standard. A 0.3 mL (30-unit) syringe gives the most precise measurement for small draws, while a 0.5 mL or 1 mL syringe is better when the draw exceeds 30 units. Keel warns you when a dose is larger than the syringe you select.
How do I convert Selank micrograms to insulin units?
Divide your dose in micrograms by the concentration in micrograms per millilitre to get the volume in millilitres, then multiply by 100 for units on a U-100 syringe. The Keel calculator does this for you and shows the draw on a to-scale syringe.
How should I store Selank after reconstitution?
Reconstituted peptides are generally kept refrigerated and protected from light, with the unmixed powder stored cooler still. Follow the guidance from your supplier or a licensed healthcare professional for the specific compound.
What if my Selank dose is larger than the syringe holds?
Either use a larger insulin syringe or reconstitute with more bacteriostatic water to lower the concentration, which increases the volume per dose so it fits. Keel flags an over-draw and you can adjust the inputs until the draw fits.
Is Selank dosing the same for everyone?
No. The right draw depends on your vial size, how much bacteriostatic water you add, and your target dose. Always recalculate when any of those change, and consult a licensed healthcare professional.
