Semax

Semax is a synthetic heptapeptide studied as an analogue of a short fragment of adrenocorticotropic hormone, ACTH(4-10). A Pro-Gly-Pro tail is added to the natural fragment to slow enzymatic breakdown, which is part of why it is investigated as a comparatively stable peptide in neurological research models. NOX supplies Semax as a lyophilised research reference material for research use only, and none of this information is medical or human-use guidance.

Semax is most often referenced in cognitive and neuroprotective research, where investigators examine attention, learning and memory-related pathways in cell and preclinical models. It is studied for mechanism and signalling rather than any applied or therapeutic outcome. As with every NOX compound, it is a research reference material intended strictly for research use only.

In the published literature Semax is frequently associated with neurotrophic signalling, and studies report changes in brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expression alongside their receptor activity. Researchers investigate how these pathways are characterised in vitro and in preclinical settings. This is educational context only; the compound is supplied strictly for research use only.

Lyophilised Semax is supplied as a sealed, freeze-dried powder and is generally kept frozen and away from light, typically stored at around -20°C for long-term stability, while for shorter periods it can be kept in the fridge at 2–8°C. Keeping the vial sealed limits moisture uptake and helps preserve the dry material. This describes general laboratory handling of lyophilised research compounds and is provided for research use only, not as guidance for any other use.

Bacteriostatic water is commonly used to reconstitute lyophilised research compounds because the small amount of benzyl alcohol it contains helps limit microbial growth in a multi-use vial. It simply dissolves the freeze-dried powder into a liquid so the material can be handled in the laboratory. Reconstitution is performed strictly within a research context; Semax is supplied by NOX for research use only.

Once reconstituted, Semax is in solution and generally less stable than the dry powder, so the liquid is typically kept in the fridge at 2–8°C and protected from light. Researchers usually prepare only what a study requires and record the reconstitution date. This reflects general laboratory handling of reconstituted research materials and is offered for research-use-only context, not as guidance for human or veterinary use.

Semax is supplied as a lyophilised powder in 10 mg. The stated strength is the mass of compound sealed in the vial before reconstitution; the working concentration depends on the volume of solvent a researcher adds during preparation. All presentations are research reference materials supplied for research use only.

Yes. Semax is supplied by NOX strictly as a research reference material for laboratory and analytical use. It is not a medicinal product, food, cosmetic or veterinary product, and nothing in these answers should be read as guidance for human or animal use.
