Semax – Research-Grade Neuropeptide | 10 mg

Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is a synthetic heptapeptide analog of a fragment of the ACTH(4-10) sequence and one of the most studied neuropeptides in modern neuroscience research. For researchers in the Netherlands and Belgium ordering Semax — batch RGXSEMAX10-2606-01 from Regenorix carries full Liquilabs certification and complete analytical documentation.

What is Semax?

Semax is a short synthetic peptide derived from a fragment of the adrenocorticotropic hormone (ACTH) sequence, modified for stability so that it resists rapid enzymatic breakdown. In research models it does not act as a hormone; instead it has been studied for its influence on neurotrophin signaling — particularly brain-derived neurotrophic factor (BDNF) and its receptor TrkB — and on the dopaminergic and serotonergic systems. Its small size and stability under laboratory conditions make it a frequently cited tool compound in neuroprotection and cognition research.

Research Applications

Semax is used in research models studying neuroprotection, BDNF and NGF neurotrophin expression, cognition and memory, cerebral ischemia and hypoxia, dopaminergic and serotonergic signaling, and synaptic plasticity. Its influence on neurotrophin pathways makes it one of the most referenced neuropeptides in central nervous system research literature.
