The Science of Semax and Selank

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.

Selank is derived from tuftsin, a peptide the immune system makes. It is studied for its effect on GABA signaling, the brain's main calming system, and on the balance of stress-related neurotransmitters. Unlike sedatives, it is studied for reducing anxiety without drowsiness or dependence.

Memory
