N-Acetyl Semax Amidate and N-Acetyl Selank Amidate function by modulating neurotransmitter systems, particularly affecting dopamine and serotonin pathways. These peptides are synthetic derivatives of naturally occurring peptides that play roles in brain function. Semax, originally developed in Russia, was extensively researched for its potential to enhance cognitive function and neuroprotection, while Selank was explored for its anxiolytic properties. Interest in combining these peptides arose from their complementary effects on brain health and mood regulation. Researchers began investigating this blend to address complex neurological issues. Today, it is primarily studied for its effects on:
- Cognitive enhancement
- Neuroprotection
- Anxiety reduction
- Mood regulation
Researchers are also looking at potential effects on stress resilience.
