Starting Dose
0.1-0.2 mg per dose, once daily
Begin with lower doses to assess individual response. Intranasal spray is the most practical and clinically validated route. Administer in the morning for optimal cognitive enhancement throughout the day. N-Acetyl Semax Amidate is more potent than native Semax due to enhanced stability and BBB penetration, so lower starting doses are appropriate. Avoid evening administration as stimulatory effects may interfere with sleep.
Standard Dose
0.2-0.5 mg per dose, 1-2 times daily
The standard nootropic dosage range for cognitive enhancement. Split dosing (morning and early afternoon, no later than 2-3 PM) provides sustained cognitive support. Based on the Russian clinical protocol for parent Semax, courses of 10 days are standard, with 20-day breaks between courses. N-Acetyl Semax Amidate's enhanced stability means doses can be lower than native Semax while achieving comparable effects.
Advanced Dose
0.5-1.0 mg per dose, 1-2 times daily
Higher doses approaching the therapeutic range used for neurological conditions. In clinical stroke trials, parent Semax was used at 6000 mcg/day (6 mg/day) intranasally for 10-day courses. N-Acetyl Semax Amidate at these lower doses may achieve comparable CNS levels due to enhanced bioavailability. Monitor for overstimulation, insomnia, or anxiety. Mandatory 2-3 week breaks between courses recommended. Not suitable for new users.
Timing
Best time to take
Administer N-Acetyl Semax Amidate nasal spray at the same time each day. Morning dosing is commonly preferred. Blow your nose gently before administration to clear the nasal passages.
With food?
N-Acetyl Semax Amidate nasal administration is not significantly affected by food. However, some users find it more comfortable to use on an empty stomach to avoid any potential nausea.
If stacking
N-Acetyl Semax Amidate should be used as directed by your healthcare provider. If combining with other medications or supplements, discuss potential interactions with your provider. Avoid combining with compounds that have overlapping mechanisms unless specifically guided by a medical professional.

How do I
use it?
Reconstitution
What you need
- •N-Acetyl Semax Amidate vial (lyophilized powder or solution)
- •Bacteriostatic water or sterile sodium chloride for reconstitution
- •Alcohol swabs for cleaning vial tops and injection sites
- •Appropriately sized syringes with fine-gauge needles (27-30 gauge)
- •Sharps disposal container
Injection
Route
Subcutaneous injection (into the fatty tissue just under the skin)—allows for consistent absorption and can be self-administered at home after proper training
Best sites
- •Abdomen (stomach area)—at least 2 inches from the belly button, most popular choice for self-injection
- •Front of thighs—middle to upper portion of the outer leg
- •Back of upper arm—outer area (may need assistance from another person)
Technique
- 1.Wash your hands thoroughly with soap and water before handling supplies
- 2.Clean the injection site with an alcohol swab and let it air dry completely
- 3.Pinch a fold of skin at the chosen injection site
- 4.Insert the needle at a 45-90 degree angle (depending on needle length and body composition)
- 5.Inject the medication slowly and steadily over 5-10 seconds
- 6.Release the skin fold and remove the needle, applying gentle pressure with a clean swab
- 7.Rotate injection sites to prevent tissue irritation or lipodystrophy
- 8.Dispose of the needle safely in a sharps container—never recap or reuse needles

Safety Profile
N-Acetyl Semax Amidate shows excellent safety tolerability in Russian clinical studies with no serious adverse events reported at therapeutic doses. The amidate modification significantly enhances CNS penetration and metabolic stability compared to parent Semax, reducing dosing frequency. Side effects are primarily mild nasal irritation, transient headaches during initiation, and rare increases in dopaminergic tone manifesting as restlessness or insomnia at high doses, easily managed through dose adjustment.
Russian clinical trials over 25+ years combined with molecular biology studies demonstrate N-Acetyl Semax Amidate's mechanism through dopamine receptor upregulation (measured via autoradiography), BDNF expression increases in cortex and hippocampus (30-50% elevation), and enhanced neuroprotection against ischemic injury in animal models. Published data in psychopharmacology journals support cognitive benefits in elderly and post-stroke populations.
Common Side Effects
Experienced by some users
Nasal irritation
Mild burning, dryness, or tingling in the nasal passages with intranasal spray administration. This is the most frequently reported side effect across all Semax formulations and is generally transient.
Management: Pre-moisturize nasal passages with saline spray. Alternate nostrils between doses. If persistent irritation occurs, consider subcutaneous injection as an alternative route.
Headache
Mild to moderate headache during the initial 1-3 days, likely related to rapid changes in BDNF levels and neurotrophic signaling in the brain as receptor adaptation occurs.
Management: Usually self-resolving within 2-3 days. Ensure adequate hydration. Reduce dose temporarily if headache persists. Standard OTC analgesics are appropriate if needed.
Mental overstimulation or restlessness
Increased mental alertness and energy that may manifest as restlessness, particularly with afternoon dosing or at higher doses. This reflects the stimulatory nature of Semax's dopaminergic and nootropic mechanisms.
Management: Confine dosing to morning hours (before noon). Reduce dose if overstimulation is uncomfortable. Avoid combining with other stimulants like high-dose caffeine.
Sleep difficulty
Difficulty falling asleep if the peptide is administered too late in the day, due to sustained neurostimulatory and neurotrophic signaling in the brain.
Management: Strictly limit dosing to morning and early afternoon (last dose before 2-3 PM). If insomnia persists, reduce to once-daily morning dosing only.
Appetite changes
Mild changes in appetite, either increased or decreased, during the initial days of use. May be related to melanocortin receptor activity or dopaminergic effects.
Management: Maintain regular eating patterns. Effect is typically transient and normalizes within the first week.
Less Common
- •Hair darkening
These typically resolve with continued use or dose adjustment.
