Semax

Semax is catalogued here as: Synthetic ACTH (4–10) analogue. Studied in rat brain tissue for BDNF, TrkB and NGF expression, molecular questions within neurotrophic-signalling research. A synthetic peptide explored in lab research on brain-cell signals, including genes involved in nerve-cell growth and maintenance.

Animal literature: The 2006 rat hippocampus study reported increased BDNF protein and regulation of BDNF and trkB messenger RNA after Semax. Molecular changes in rats are not demonstrated memory or focus benefits in people, nor findings about this formulation.

Animal literature: The 2007 study reported region-specific NGF and BDNF gene-expression changes, including increased expression in rat hippocampus and decreased NGF expression in frontal cortex. Gene- and region-specific animal findings do not establish human cognitive enhancement or clinical neuroprotection.

When comparing published work, match the exact molecular identity, salt form and strength to the paper. Findings in cell or animal models describe those models only and do not establish outcomes in people. The reconstitution calculator converts vial content and diluent volume into concentration for laboratory preparation.
