Semax
Semax is a synthetic heptapeptide derived from the ACTH (4-10) fragment with a stabilizing Pro-Gly-Pro C-terminal modification. It modulates BDNF expression, dopaminergic signaling, and neurotrophic factor pathways without affecting adrenal cortisol production. Research examines its neuroprotective and cognitive-enhancing properties.
