Product Overview
Semax is a seven-amino-acid analog of the ACTH(4-7) fragment, stabilized with a Pro-Gly-Pro sequence. The design preserves the core signaling interest of the ACTH fragment while improving metabolic stability for research applications.
Semax is most closely associated with brain-derived neurotrophic factor (BDNF), dopaminergic signaling, memory formation, learning, attention, and recovery after neurological stress. Researchers also examine its effects on gene expression, oxidative stress, and neuroplasticity – the brain’s ability to adapt and reorganize.
For cognitive-research projects that need more than a generic stimulant model, Semax provides a targeted peptide approach centered on growth-factor and neural-adaptation pathways.
