Semax is a synthetic peptide derived from the ACTH (Adrenocorticotropic hormone) molecule, specifically a fragment of ACTH(4-10). It's been extensively studied in Russia and Eastern Europe for its neuroprotective, cognitive-enhancing, and potentially therapeutic properties.

 

Structure and Mechanism

- *Sequence*: Met-Glu-His-Phe-Pro-Gly-Pro (7 amino acids)

- *Action*: Modulates neurotransmitter systems, enhances neuroplasticity, and promotes neurotrophic factors like BDNF

- *Targets*: Influences opioid, dopaminergic, and serotonergic pathways

 

Key Benefits and Effects

- *Cognitive Enhancement*: Improves memory, attention, and learning

- *Neuroprotection*: Reduces oxidative stress, protects against ischemia/reperfusion injury

- *Mood and Stress*: May have antidepressant and anxiolytic effects

- *Circulatory*: Improves cerebral blood flow and microcirculation

 

Administration and Dosage

- *Intranasal*: Common route, ~50-100 mcg per dose, 1-3 times daily

- *Subcutaneous/IM*: Sometimes used, dosage varies (typically 0.5-1 mg daily)

- *Cycles*: Often 5-7 days on, 2 days off, but protocols vary

 

Research and Use

- Studied for stroke recovery, cognitive impairment, and neurodegenerative conditions

- Used off-label for cognitive enhancement and neuroprotection

- Generally considered safe, but human trials are limited outside Eastern Europe
