N-Acetyl Semax Amidate Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for N-Acetyl Semax Amidate. All information is for educational purposes only.

Quick Answer

N-Acetyl Semax Amidate (NASA) dosing is extrapolated from Semax research, typically using 100–500 mcg per dose, administered 1–3 times daily via nasal spray. Due to enhanced stability, lower doses may be effective. No human dose-ranging trials have been completed; dosing is empirical based on user reports.

Standard Dosage Range

Research dosing range: 100–500 mcg per dose (nasal spray)

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Cognitive Enhancement

200–400 mcg1–2× daily
Duration

2–8 weeks

Administered via nasal spray. Start at the low end of the range and titrate up as needed. Cycle with breaks to avoid tolerance.

Anxiety Reduction / Mood Support

100–300 mcg1–2× daily
Duration

2–6 weeks

Administered via nasal spray. May be more effective when combined with lifestyle interventions (exercise, meditation).

Focus & Attention

200–500 mcg1–3× daily
Duration

2–8 weeks

Administered via nasal spray. Optimal timing varies by individual; experiment with pre-work or pre-study dosing.

Neuroprotection

200-300 mcg1-2x daily
Duration

4-12 weeks

Nasal Spray. Experimental use only; long term use effects are unknown.

Timing & Frequency

Administer via nasal spray in the morning and/or early afternoon to avoid sleep disruption. The effects are typically felt within 30–60 minutes. Avoid use close to bedtime.

Cycle Guidance

User reports suggest cycling NASA to avoid tolerance, typically using a 4–8 week cycle followed by a 2–4 week break. As with all peptides, long-term human safety data is limited, so cycling is precautionary.

Reconstitution Reference

Quick reference for reconstituting N-Acetyl Semax Amidate. For custom vial sizes and concentrations, use the Reconstitution Calculator.

Common Vial SizeTypically 10 mg per vial (lyophilized powder)
BAC Water Volume10 mL bacteriostatic water for 1 mg/mL concentration
Concentration & DrawAt 1 mg/mL: 200 mcg = 0.2 mL (20 units on a 100-unit insulin syringe). Dilute further in nasal spray bottle with saline solution.
StorageRefrigerate at 2–8°C after reconstitution. Keep lyophilized powder at room temperature or refrigerated.
StabilityReconstituted solution stable up to 30 days refrigerated. Lyophilized powder stable 12–24 months per manufacturer specifications.
Use the Reconstitution Calculator → for precise injection volumes based on your exact vial size, water volume, and desired dose.
