N-Acetyl Semax Amidate
NA-Semax · N-Acetyl-Semax · Semax Amidate
N-Acetyl Semax Amidate is a modified, more stable analogue of Semax, a synthetic peptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10). Semax was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and has been approved in Russia since the 1990s for treatment of stroke, cognitive disorders, and peptic ulcers. The N-acetyl amidate modification increases resistance to enzymatic degradation, enhancing bioavailability and extending its duration of action.
Same as Semax but longer-acting. 1-2 daily doses sufficient. No fasting required.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
How it works
Stimulates expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), promoting neuronal survival, growth, and synaptic plasticity.
Modulates dopaminergic and serotonergic neurotransmission, enhancing attention, motivation, and mood without stimulant-like side effects.
Provides neuroprotective effects through anti-inflammatory and antioxidant mechanisms, reducing glutamate excitotoxicity during ischemic events.
What to expect
Days 1-7: Subtle improvements in mental clarity, focus, and alertness. Some users report effects within hours.
Evidence
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: 100-600mcg; Subcutaneous (SubQ); daily. No checked live PubMed abstract verified this exact displayed dose, route, and frequency for the same molecule/formulation and relevant population.
Mechanism: Stimulates expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), promoting neuronal survival, growth, and synaptic plasticity.. No checked live PubMed abstract provided an exact-molecule/formulation sentence supporting this source-JSON mechanism claim.
Primary safety claim: Mild headache, especially during initial use. No checked live PubMed abstract directly verified this source-JSON safety claim at the displayed formulation, route, and regimen.
Interactions & stacking
Two different questions: what is documented about running these together, and what is documented about drawing them into the same syringe. A good pharmacological partner can still have to be pinned separately.
Documented together
Keep separate
Check any specific pair in the Stack & Interaction Checker, which answers both questions separately. Absence of a documented conflict is not evidence of safety.
Pharmacokinetics
Enhanced vs native Semax
SubQ, ~5-10 min intranasal
Enhanced vs native Semax due to N-acetyl amidate modification. SubQ absorption near-complete. Intranasal ~30-40% (partial BBB bypass).
Nootropic and neuroprotective effects
Enzymatic degradation (peptidases; N-acetyl amidate modification slows proteolysis)
Storage. Store refrigerated at 2-8C. Protect from light. Reconstituted solution stable for up to 28 days refrigerated.
Regulatory status
Approved pharmaceutical in Russia for stroke, cognitive disorders, and optic nerve disease. Not FDA-approved. N-Acetyl Semax Amidate is sold as a research compound in Western countries.
