How It Works

The optimization of cognitive function through peptide therapy is achieved by leveraging the distinct yet complementary mechanisms of action of neurocognitive peptides like Semax and Selank. These molecules act as sophisticated biological messengers, targeting key pathways involved in neural plasticity, neurotransmission, and neuroprotection.

Semax is a synthetic heptapeptide, a fragment of adrenocorticotropic hormone (ACTH), specifically ACTH(4-10) with a Pro-Gly-Pro sequence. Despite its origin, Semax does not possess hormonal activity but acts as a potent nootropic and neuroprotector. Its primary mechanisms of action include:

• Modulation of Neurotransmitters: Semax influences the levels and activity of key neurotransmitters such as dopamine, serotonin, and norepinephrine. By optimizing their balance, it enhances mood, motivation, and cognitive processing speed.
• Neurotrophic Factor Enhancement: Semax has been shown to increase the expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF). BDNF is crucial for neuronal survival, growth, and synaptic plasticity, which are fundamental for learning and memory formation. NGF supports the growth and maintenance of neurons [Semax Cognitive Vitality For Researchers, Alzheimer's Drug Discovery Foundation].
• Antioxidant and Anti-inflammatory Effects: Semax exhibits neuroprotective properties by reducing oxidative stress and inflammation in the brain, safeguarding neurons from damage caused by various stressors, including hypoxia (low oxygen) Sharma et al., 2012.
• Improved Cerebral Circulation: It can enhance blood flow to the brain, ensuring adequate oxygen and nutrient supply, which is vital for optimal cognitive function.

Selank is a synthetic anxiolytic heptapeptide, a derivative of the endogenous immunomodulatory peptide tuftsin. It is primarily known for its anxiolytic (anti-anxiety) and nootropic effects, working through several mechanisms:

• GABAergic System Modulation: Selank positively modulates the GABAergic system, increasing the activity of GABA, the primary inhibitory neurotransmitter in the brain. This leads to a calming effect, reducing anxiety and stress without causing sedation Functional Connectomic Approach to Studying Selank and Semax, 2020.
• Neurotransmitter Balance: Similar to Semax, Selank also influences the balance of monoamine neurotransmitters, contributing to mood stabilization and improved emotional regulation.
