Semax Peptide Overview

Semax peptide is a synthetic heptapeptide derived from adrenocorticotropic hormone (ACTH 4-10) with the addition of a C-terminal Pro-Gly-Pro sequence. It is studied in laboratory and preclinical models for its influence on neuronal signaling, CNS pathway dynamics, and molecular stress responses. Research has investigated its ability to modulate neurotrophic factor expression, neurotransmitter systems, and oxidative stress pathways.

Related neuropeptide research materials in the Medicina Labs catalog include Selank and DSIP.

History

Semax was developed in Russia in the 1980s–1990s as part of research on synthetic peptides with potential neuromodulatory effects. It was designed to retain the neuroactive core of ACTH while eliminating hormonal activity, thereby providing a stable and non-hormonal peptide for CNS research. Over time, studies expanded into its roles in neuronal signaling characterization, synaptic plasticity, and regulation of gene expression in experimental brain models.

Research Findings

Semax has been studied in neurological, CNS, and systemic models, with research highlighting its role in neuronal signaling, synaptic pathway dynamics, and stress response. Studies also report activity in neurotransmitter modulation, oxidative stress pathways, and signaling dynamics in preclinical settings.

Key Areas of Research:

  • Neurological: Neuronal signaling, pathways, cascades
  • CNS: Synaptic plasticity, signaling, function
  • Systemic: Stress pathways, neurotrophin expression, gene regulation

Together, these findings suggest broad experimental potential for Semax across neurological, CNS, and systemic pathways. By influencing neurotransmitter systems and neurotrophic factor expression, Semax provides a versatile platform for research into CNS dynamics, stress biology, and gene-expression regulation in laboratory settings.

Common Questions

Purity is measured by HPLC (High-Performance Liquid Chromatography), which separates and quantifies each component in a sample. The result is reported as a percentage on the Certificate of Analysis (COA), along with the chromatogram, for every batch.
All our peptides are tested by independent third-party labs and consistently achieve 99.4%+ purity. Every product ships with a Certificate of Analysis so you can verify the exact purity of your specific batch.
