About Semax

Semax is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10), modified with a Pro-Gly-Pro tail to extend stability. It has been studied for its effects on BDNF and NGF expression, dopaminergic and serotonergic systems, and neuroprotective signalling pathways in laboratory models. Supplied as a lyophilised powder for in vitro research use only.
