An ACTH-related peptide explored in intranasal neurological research.
This profile separates the compound’s scientific background from specification-specific preparation and source schedules. Begin with the research findings and limitations, then select the formulation you want to examine.
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 source now uses nasal preparation and actuator tables. Findings from a documented nasal formulation should not be transferred to an injection schedule.[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 Semax.
A comprehensive adverse-effect profile is not established by the source record. Consult the cited studies for what was measured and what remains uncertain.

Semax 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.
Research Amount to Spray Equivalents
| Research Amount | 5 mL Option200 mcg per Spray | 10 mL Option100 mcg per Spray |
|---|---|---|
| 200 mcg | 1 spray | 2 sprays |
| 300 mcg | 1.5 theoretical sprays | 3 sprays |
| 400 mcg | 2 sprays | 4 sprays |
| 500 mcg | 2.5 theoretical sprays | 5 sprays |
These rows are concentration conversions. They do not turn one study amount into a universal schedule. Fractional results are mathematical only because a metered pump cannot deliver half of a full actuation. 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 Semax Research
| Source | Research Context | Published Intranasal Amount and Formulation |
|---|---|---|
| Kaplan et al., 1996[1] | Healthy volunteers in operator and EEG experiments | Experiments included 0.210 mg and 1 mg exposures. The operator experiment reported 1 mg in 0.4 mL physiological solution. |
| Lebedeva et al., 2018[2] | Healthy volunteer fMRI study | One 1.2 mg exposure using a 1% solution, with 60 microliters placed into each nostril. |
| Gusev et al., 2018[3] | Condition-specific post-stroke research | 6,000 mcg per day for 10 days, followed by a second 10-day course after a 20-day interval. |
| Official 0.1% Semax instructions[4] | Registered intranasal drop formulation | 1 mg/mL in purified water with methylparaben. Each 0.05 mL drop contained 50 mcg. |
Human Semax 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 10 mL calculation above produces 1 mg/mL, which matches the concentration of the registered 0.1% drop formulation. The device and formulation are still different, so concentration equivalence does not establish identical delivery, stability, or dosing.

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

- 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. Kaplan and colleagues reported physiological solution in one human experiment. The registered 0.1% Semax product used purified water with methylparaben, so the saline example is not the same as the registered multidose formulation[1][4].
Storage Instructions
Storage depends on the complete formulation, container, and handling method.
- Registered 0.1% product: Protected from light, stored at no more than 10 degrees C, and not frozen[4].
- Custom research preparation: Use formulation-specific stability and microbiological controls.
- Labeling: Record preparation date, final volume, concentration, vehicle, and storage conditions.
- Handling: Keep the cap secured and minimize unnecessary warming and light exposure.
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.
