Semax is a synthetic peptide analog of adrenocorticotropic hormone (ACTH), specifically based on the ACTH(4-10) fragment with a Pro-Gly-Pro C-terminal extension. Like Selank, it was developed by Russian researchers and has been the subject of a significant body of published research, primarily from Russian and Eastern European laboratories.
The research profile of Semax centers on neurotrophic and neuroprotective effects. Studies have examined its influence on BDNF expression, cognitive function in various animal models, and cerebrovascular function. Some researchers have also explored its effects on gene expression profiles in brain tissue, revealing potential involvement in multiple neurological pathways. It is a genuinely interesting molecule if you work in neuroscience research.
The Pro-Gly-Pro modification enhances stability against enzymatic degradation, giving it a longer effective duration than the native ACTH fragment. This makes it more practical for experimental protocols.

For research use only. Not intended for human consumption.
This product is verified at ≥97% purity via reverse-phase HPLC analysis. A batch-specific Certificate of Analysis (COA) documenting exact purity percentage, mass spectrometry results, and appearance is included with your order.
Store the unopened lyophilized vial at -20°C in a dry environment. Once reconstituted, divide into single-use aliquots and store frozen at -20°C. Avoid repeated freeze-thaw cycles. Properly stored lyophilized powder has a shelf life of approximately 24 to 36 months.
Add bacteriostatic water or sterile water slowly along the vial wall. Do not spray directly onto the lyophilized powder. Gently swirl until completely dissolved. Do not vortex. See our full reconstitution guide for detailed instructions and solvent selection.
