Where Semax sits in the melanocortin family

Semax belongs to a family of brain-active peptides cleaved from one large precursor protein. Understanding that family explains both what Semax can do and why its exact molecular target is still debated.

This unit places Semax in the ACTH and melanocortin system, shows why it drives brain signaling without raising cortisol, and walks through the honest uncertainty about which receptor it actually binds.
