Semax

Product Description & Research Overview

Semax is a synthetic heptapeptide derived from adrenocorticotropic hormone (ACTH) fragment 4–10 that has been extensively researched for its nootropic, neuroprotective, and neurorestorative properties. Originally developed in Russia for stroke recovery, Semax has since become one of the most studied cognitive peptides for supporting memory, focus, learning, and overall brain function.

Research suggests Semax increases brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) while modulating dopaminergic and serotonergic neurotransmitter systems involved in cognition, mood, and motivation. Unlike many cognitive compounds, it crosses into the central nervous system through direct transport via the olfactory epithelium and trigeminal nerves when administered intranasally, allowing rapid brain penetration.

Originally developed for neurological recovery, Semax continues to be investigated for applications involving stroke rehabilitation, traumatic brain injury, cognitive enhancement, neurodegenerative disorders, learning capacity, and healthy aging. Functional MRI (fMRI) studies have demonstrated increased default mode network activity, while clinical research has reported improvements in cognitive performance, attention, and recovery following neurological injury.

Semax remains one of the most extensively researched neuropeptides in Russian medical literature and is recognized for its favorable safety profile and broad neuroprotective potential.

Mechanism of Action

Research suggests Semax supports brain function through several complementary mechanisms:

  • Increases brain-derived neurotrophic factor (BDNF)
  • Enhances nerve growth factor (NGF) production
  • Promotes neuroplasticity and neural connectivity
  • Modulates dopamine and serotonin signaling
  • Supports learning, memory formation, and mood regulation
  • Crosses into the central nervous system through intranasal transport via the olfactory epithelium and trigeminal nerves
  • Injectable administration provides longer systemic exposure, while intranasal delivery offers rapid central nervous system penetration

 

  • Supports focus, attention, and mental clarity
  • Enhances memory formation and learning capacity
  • Promotes neuroplasticity and brain resilience
  • Supports healthy mood and motivation
  • May improve mental stamina and cognitive performance
  • Supports recovery following neurological injury
  • Enhances neural connectivity
  • May provide sustained cognitive improvements with consistent use
