Key Ingredients
A synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from adrenocorticotropic hormone. Research documents effects on BDNF expression, neuronal survival, and cognitive function in pre-clinical models.
Discover the researchDescription
Semax is a synthetic heptapeptide analog of the ACTH(4-10) fragment with the sequence Met-Glu-His-Phe-Pro-Gly-Pro. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Semax has been studied for its nootropic and neuroprotective properties.
Research Background
Semax has been investigated in preclinical models for its effects on brain-derived neurotrophic factor (BDNF) expression, cognitive function, and neuroprotection. Unlike the parent ACTH molecule, Semax does not exhibit steroidogenic activity, making it a selective tool for studying melanocortin-mediated neuroprotection. For research use only.
Semax is also stocked combined 1:1 with Selank as a single Semax and Selank nasal spray (15mg of each per bottle) for programs that study both heptapeptides.
