Semax is a neuropeptide derived from the ACTH 4–10 fragment, extensively researched for its role in neurotrophic signalling, synaptic modulation, and neuronal plasticity. Scientific studies highlight its influence on brain derived neurotrophic factor (BDNF) expression, neurotransmitter regulation, and gene expression pathways associated with neural adaptation. Due to its stability and targeted molecular activity, Semax is widely utilised in neuroscience /cognitive research.
