The Science of Semax

Semax is a short peptide derived from a fragment of ACTH, a hormone involved in the stress response, modified so it acts on the brain without the hormonal effects. It is studied for raising BDNF, a protein that supports the growth and connection of neurons and is tied to learning, memory, and focus.

Research on Semax has looked at attention, memory, and mental performance under load, as well as its effect on dopamine and serotonin signaling. It is not a stimulant, and it is not studied as one.
