Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from the ACTH(4–10) fragment, enhanced with a Pro-Gly-Pro stabilizing motif. It is commonly used in research examining central nervous system signaling, particularly through modulation of BDNF, TrkB receptors, and neurotrophin-regulated transcription factors such as NGF and GAP-43.

Semax has demonstrated neurotrophic, antioxidant, and monoaminergic effects in preclinical models, making it a popular peptide in experimental neuroscience for studies involving neuroplasticity, memory, stress response, and oxidative regulation. This formulation contains 11mg of lyophilized peptide, ideal for precision dilution and laboratory assay designs.
