What is Semax?

Semax (MEHFPGP) is a heptapeptide analog of the ACTH(4-10) fragment, studied for BDNF expression, dopaminergic tone, and stress-response pathways in neural models.

Unlike full-length ACTH, Semax allows separation of central neuropeptide actions from peripheral steroidogenesis in many protocols.

Supplied for lawful laboratory research — not for human cognitive enhancement or self-administration.
