How it works
Potential benefits & side effects
Interpret each outcome in the context of the study population, formulation and evidence type. Research findings do not establish a personal treatment outcome.
Potential benefits & research findings
The current source emphasizes human intranasal studies and measured actuator output. Nasal drops, sprays and systemic administration should not be treated as equivalent.[1][2][3]
Read the original publications to see the measured endpoints, comparator, duration and uncertainty. Mechanistic plausibility and a favorable experimental result are different from demonstrated clinical benefit.
Side effects & evidence limitations
Interpret the reported adverse effects together with the study population, route and observation period. Small or short studies can miss uncommon and delayed harms. Evidence from a related compound does not establish the safety of Selank.
A comprehensive adverse-effect profile is not established by the source record. Consult the cited studies for what was measured and what remains uncertain.

Selank 10 mg Nasal Spray Calculations
| Measured Final Volume | Vehicle Added After Transfer | Final Concentration | Per Verified 0.10 mL Spray |
|---|---|---|---|
| 5.0 mL | About 2.0 mL | 2,000 mcg/mL | 200 mcg50 nominal sprays |
| 10.0 mL | About 7.0 mL | 1,000 mcg/mL | 100 mcg100 nominal sprays |
Both options begin with 3.0 mL in the peptide vial. Transfer the complete solution, then add enough vehicle to reach the measured final volume. Calculation basis: Each row uses the full 10 mg vial and a pump verified to release 0.10 mL per complete actuation. Nominal spray counts are calculated before priming and normal residual hold-up.
Mathematical Actuator Equivalents
| Literature Amount | 5 mL Option200 mcg per Spray | 10 mL Option100 mcg per Spray |
|---|---|---|
| 300 mcg | 1.5 theoretical sprays | 3 sprays |
| 900 mcg | 4.5 theoretical sprays | 9 sprays |
| 2,700 mcg | 13.5 theoretical sprays | 27 sprays |
These rows are concentration conversions, not a universal schedule. Fractional results are mathematical only because a metered pump cannot deliver half of a full actuation. Amounts reported with a manufactured drop formulation should not be treated as direct generic-pump instructions. Use the measured final volume and verified actuator output in every calculation. Bottle capacity alone does not establish the final volume or the amount delivered per spray.
Published Human Intranasal Selank Research
| Source | Research Context | Published Intranasal Amount and Formulation |
|---|---|---|
| Zozulia et al., 2008[1] | 62 adults with generalized anxiety disorder or neurasthenia | Selank 0.15% nasal drops at 2.7 mg per day, reported as 36 drops divided across three administrations, with outcomes followed through day 14. |
| Syunyakov et al., 2012[2] | 20 adults with generalized anxiety disorder | 2,700 mcg per day intranasally. The pharmaco-EEG analysis also examined a single 900 mcg exposure. |
| Panikratova et al., 2020[3] | Healthy-volunteer functional connectivity study | One intranasal exposure using 0.15% Selank solution, 60 microliters per nostril, described as a 0.2 mg total amount. |
Human Selank research has primarily used the intranasal route. The studies below show the reported amount, formulation, and research setting so visitors can compare the literature without treating different protocols as interchangeable. The current manufacturer instruction describes a 0.15% nasal-drop product at 1.10 mg/mL, with two drops placed in each nasal passage three times daily for 14 days[4]. Those drop counts belong to the registered bottle and finished formulation. They are not direct equivalents to a different metered pump. Reference concentration: Mathematically, 10 mg brought to about 6.67 mL equals 1.10 mg/mL. A verified 0.10 mL actuation at that concentration contains 150 mcg. This is a concentration comparison, not a reproduction of the registered preserved drop product.
Core Formula
| Verified Actuator Output | 5 mL Option2,000 mcg/mL | 10 mL Option1,000 mcg/mL |
|---|---|---|
| 0.05 mL | 100 mcg | 50 mcg |
| 0.10 mL | 200 mcg | 100 mcg |
| 0.13 mL | 260 mcg | 130 mcg |
mcg per spray = (10,000 mcg / final volume in mL) x verified mL per spray nominal sprays = final volume in mL / verified mL per spray
Additional schedule context & duration
Quick reference for the intranasal Selank 10 mg calculation.
- Human research route: Intranasal drops or solution.
- Peptide amount: 10,000 mcg total in the vial.
- 5 mL option: 2,000 mcg/mL and 200 mcg per verified 0.10 mL spray.
- 10 mL option: 1,000 mcg/mL and 100 mcg per verified 0.10 mL spray.
- Final-volume rule: Bring the transferred solution to an exact measured final volume.
Preparation
How to Prepare the 5 mL or 10 mL Research Bottle
- Confirm the 10 mg vial, selected sterile research vehicle, actuator bottle capacity, and documented pump output.
- Add 3.0 mL of compatible sterile vehicle to the vial with aseptic transfer technique.
- Gently swirl until the contents are dissolved. Do not shake.
- Transfer the complete 3.0 mL solution into a sterile 5 mL or 10 mL nasal actuator bottle.
- Add enough vehicle to reach a measured final volume of exactly 5.0 mL or 10.0 mL. The theoretical additions are approximately 2.0 mL and 7.0 mL.
- Secure the pump and label the bottle with the peptide amount, final volume, concentration, pump output, and preparation date.
- Prime the pump according to the actuator instructions and record the priming sprays in the research log.
Vehicle context: The worked example can use sterile 0.9% saline as a research vehicle. The registered 0.15% Selank product contains 1.10 mg/mL Selank in purified water with methylparaben, so the saline example is not the same as the manufactured multidose drop formulation[4].
Storage Instructions
Storage depends on the complete formulation, container, and handling method.
- Registered 0.15% product: Protected from light, stored at no more than 10 degrees C, and not frozen[4].
- Opened registered product: The manufacturer permits storage at no more than 25 degrees C for up to 15 days[4].
- Custom research preparation: Use formulation-specific stability and microbiological controls rather than transferring the finished-product shelf life.
- Labeling: Record preparation date, final volume, concentration, vehicle, and storage conditions.
Nasal Actuator Technique
Use a standardized device procedure so the recorded amount remains consistent across research observations.
- Inspect the labeled concentration and confirm the actuator output before use.
- Prime or reprime the pump according to the manufacturer instructions.
- Keep the bottle in the specified orientation and use one complete, smooth stroke.
- Record each actuation immediately, including priming sprays.
- Wipe the nozzle with a clean material appropriate for the device and replace the cap.
- Return the bottle to its documented storage condition after the research procedure.
