What Is Semax?

Semax is a synthetic heptapeptide (seven–amino acid peptide) developed in Russia and widely studied for its potential neurological and cognitive-supporting effects. Originally designed for clinical use in neurological recovery, Semax is researched today for its roles in memory support, focus, neuroprotection, and stress modulation.

This peptide is an analog of ACTH(4-10)—a fragment of the adrenocorticotropic hormone—but unlike ACTH, Semax does not impact cortisol or hormone levels. Instead, it is studied for its interaction with brain-derived neurotrophic factor (BDNF) and other pathways linked to learning, mood, and neural function.

Researchers explore Semax for its potential effects on:

Cognitive enhancement and focus
Memory formation and recall
Neuroprotection
Mood and stress response
Circulation and oxygenation in neural tissue
