Semax Dosage (5 mg Vial) Protocol dosage chart
This Semax dosage chart explains how a 5 mg vial can be calculated for intranasal research with a verified 0.10 mL metered actuator. Published human Semax studies primarily used intranasal drops or measured intranasal solution. A measured 5 mL final volume provides 100 mcg per spray, while a measured 10 mL final volume provides 50 mcg per spray.
- Primary human research route
- Intranasal drops or measured intranasal solution.
- 5 mL final volume
- 1 mg/mL, 100 mcg per verified 0.10 mL spray, and 50 nominal sprays.
- 10 mL final volume
- 0.5 mg/mL, 50 mcg per verified 0.10 mL spray, and 100 nominal sprays.
- Device check
- Confirm the pump output and follow its priming instructions before using the calculation.
- Research context
- Published amounts varied by study population, formulation, and research objective.

Published Human Intranasal Semax Research
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 5 mL calculation above also 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.
Nasal Spray Actuator Math
A 0.10 mL actuator is a common nasal pump configuration, but pump output is not universal. Pharmaceutical literature reports pump volumes from approximately 0.025 mL to 0.20 mL per spray. Use the manufacturer specification or a validated measurement for the exact device.
mcg per spray = (5,000 mcg / final volume in mL) x verified mL per spray
nominal sprays = final volume in mL / verified mL per spray
- Confirm the stated volume per full actuation for the specific pump.
- Follow the documented priming and repriming procedure.
- Record residual volume and tail-off near bottle exhaustion when estimating usable sprays.
- Keep pump orientation and actuation stroke consistent during the research procedure.
Important Notes
Small measurement and device details can materially change the amount delivered per spray.
- Use a measured final volume, not the bottle capacity mark alone.
- Verify that the actuator releases 0.10 mL per full stroke before applying the main table.
- Prime and reprime exactly as specified for the pump, then record those actuations.
- Keep the bottle upright and use a complete, consistent stroke for each recorded spray.
- Treat the theoretical 50 or 100 sprays as nominal counts because priming and residual hold-up consume part of the volume.
- Use a validated laboratory handling and stability plan for any custom multidose preparation.
How Intranasal Semax Research Works
Semax is a synthetic heptapeptide based on the ACTH(4-10) sequence and was developed without the hormonal activity of full-length ACTH. Published research has examined neurotrophic signaling, attention, memory, and condition-specific neurological outcomes. Intranasal delivery places a measured solution on the nasal mucosa, which is the route used in the human studies summarized on this page.
The calculation is concentration based. Dividing 5,000 mcg by the measured final volume gives mcg per mL. Multiplying that concentration by the verified pump output gives mcg per spray.
Human Research Findings and Observations
Semax findings should be read together with the population, amount, formulation, and study design.
- Healthy-volunteer studies reported changes in attention, operator performance, EEG measures, or functional connectivity after intranasal exposure.
- Condition-specific studies evaluated neurological recovery and other outcomes using protocols that were substantially different from healthy-volunteer experiments.
- The official 0.1% drop instructions report possible mild nasal mucosal irritation with prolonged use.
- Pump output, formulation, nasal condition, and administration technique can affect the delivered amount and deposition pattern.
Research Controls That Affect Nasal Delivery
Consistent technique improves the value of recorded research observations.
- Pump specification: Record the stated or measured mL per actuation.
- Priming status: Document first use, repriming, and any missed sprays.
- Actuation technique: Keep bottle orientation, stroke length, and stroke force consistent.
- Nasal condition: Record congestion, irritation, or other conditions that could affect deposition.
- Formulation details: Record the vehicle, final volume, concentration, container, and storage conditions.
- Actuation count: Track sprays from priming through final use to identify tail-off and residual volume.
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.

Semax Dosage (5 mg Vial) Protocol dosage FAQs
What does the Semax Dosage (5 mg Vial) Protocol dosing schedule look like?
5.0 mL — About 2.0 mL — 1,000 mcg/mL — 100 mcg50 nominal sprays; 10.0 mL — About 7.0 mL — 500 mcg/mL — 50 mcg100 nominal sprays. The full table above lists every step with matching syringe units.
How should reconstituted Semax Dosage (5 mg Vial) Protocol be stored?
Once mixed, Semax Dosage (5 mg Vial) Protocol is kept refrigerated at roughly 2–8 °C, protected from light, and never frozen. Unmixed lyophilised powder is the more stable form and is only reconstituted when it is needed.
How many insulin syringe units equal a Semax Dosage (5 mg Vial) Protocol dose?
Units depend on the water volume you used. Divide your target dose by the vial concentration to get millilitres, then multiply by 100 — 1 unit on a U-100 insulin syringe is 0.01 mL. The Spartan Peptides reconstitution calculator does this conversion for you.
Is Semax Dosage (5 mg Vial) Protocol approved for human use?
No. Semax Dosage (5 mg Vial) Protocol is sold and referenced strictly as a research chemical. Nothing on this page is medical advice and the material is not for human consumption.
Educational and research information only. Not medical advice, not for human consumption. Values are reference figures — always verify your own math with the reconstitution calculator.
On any insulin syringe, 1 unit = 0.01 mL, so unit counts above hold across brands.
