Semax

Semax is a synthetic peptide derived from a fragment of ACTH (adrenocorticotropic hormone). It is mainly studied for potential nootropic and neuroprotective effects, including support for focus, memory, learning, and mental performance. It may also influence dopamine and BDNF (brain-derived neurotrophic factor) activity in the brain, which is why it is sometimes associated with improved mood, motivation, and cognitive function.
