Semax

Semax is a synthetic heptapeptide analogue of ACTH(4-7) developed in Russia and used clinically for stroke recovery and cognitive enhancement. It is one of the most well-researched nootropic peptides, with strong evidence for BDNF upregulation, neuroprotection, and enhancement of memory and attention.
