How to Administer Semax
Semax is a synthetic peptide analog of ACTH administered intranasally—it is NOT injected. The nasal spray route provides rapid absorption through the nasal mucosa with direct access to the central nervous system, making it the preferred and standard route for this nootropic peptide.
Recommended Injection Sites
Nasal Mucosa
PrimarySemax is administered as an intranasal spray, not by injection.
Injection Technique
Wash Hands
Wash hands with soap and water for 20+ seconds.
Prepare the Spray
If using a pre-mixed nasal spray, prime the pump if first use (2-3 pumps into air). If reconstituting, follow the manufacturer instructions for the nasal delivery device.
Clear the Nasal Passage
Gently blow your nose to clear the nasal passages. This ensures better absorption of the peptide through the nasal mucosa.
Administer the Spray
Tilt your head slightly forward. Insert the nozzle into one nostril, aiming slightly outward (toward the ear). Press the pump while inhaling gently through the nose.
Alternate Nostrils
If multiple sprays are needed, alternate between nostrils. Avoid sniffing hard or blowing your nose for 10-15 minutes after administration.
Timing & Frequency
Typically administered in the morning for cognitive enhancement. Can be used 1-3 times daily.
1-3 times daily, depending on the research protocol and concentration.
Site Rotation
Alternate nostrils with each administration to reduce mucosal irritation.
Local vs Systemic Effects
Semax is absorbed through the nasal mucosa for systemic distribution. The intranasal route provides rapid absorption and avoids first-pass liver metabolism.
Warnings & Precautions
- !Semax is not FDA-approved.
- !Do not inject Semax—it is formulated for intranasal use only.
- !Nasal congestion may reduce absorption—clear passages before use.
- !Store nasal spray in refrigerator.
Frequently Asked Questions
Can Semax be injected instead of used as a nasal spray?
While some researchers have studied injectable forms, Semax is designed and validated for intranasal administration. The nasal route provides rapid CNS access without the need for injection. Do not inject a nasal formulation.
How quickly does intranasal Semax take effect?
Nasal absorption is rapid. Effects on cognition and focus are typically reported within 15-30 minutes of administration.
