Semax: #

• Acronym: Semax
• Amino Acid Sequence: Met-Glu-His-Phe-Pro-Gly-Pro
• Primary Functions and Actions:
  • Enhances cognitive function and memory.
  • Reduces anxiety and stress.
  • Promotes neuroprotection and brain repair.
  • Protects neurons from oxidative damage.
  • Promotes neurogenesis (formation of new neurons).
• Mechanism of Action:
  • Semax is a synthetic peptide derived from adrenocorticotropic hormone (ACTH).
  • It modulates the levels of brain-derived neurotrophic factor (BDNF) – the brain’s neurotransmitter systems, and other neurotransmitters  including dopamine, serotonin, and norepinephrine improving synaptic plasticity and neuroprotection.
  • It also reduces oxidative stress and inflammation in the brain, supporting neuronal survival and repair.

• Systems Activated:
  • Nervous System: Enhances cognitive function, reduces anxiety, and promotes neuroprotection.
  • Nervous System: Enhances cognitive function and protects neurons.
  • Endocrine System: Modulates stress responses.
  • Immune System: Reduces inflammation in the brain.
• Dosage and Timing:
  • Dosages vary, but common protocols suggest 50-200 mcg per day, administered via nasal spray or subcutaneous injection.
  • Timing is not critical, but it is often used in the morning for cognitive enhancement.
• Contraindications and Side Effects:
  • Contraindications are not well-established due to limited human studies.
  • Side effects are generally mild and may include mild headache or nasal irritation with nasal spray.
• Potential Uses:
  • Cognitive enhancement
  • Anxiety and stress reduction
  • Neuroprotection and brain repair
  • Recovery from brain injuries
