What does semax and selank do?

Both are lab-made peptides developed in Russia and approved there for certain uses, but they aim at different things. Semax, a piece of the hormone ACTH, is approved for stroke and thinking problems. It is studied for protecting nerve cells through BDNF (a protein that helps brain cells grow) and for focus. Selank, a lab-made copy of tuftsin (a small immune peptide), is studied for easing anxiety and stress without the drowsiness typical of sedatives (benzodiazepines). Neither is FDA approved.
