Semax: a research overview
Semax is a short synthetic peptide studied in cognitive and neuroscience research contexts. This overview describes what it is and how it is handled in the lab, with no therapeutic or dosing claims.
What it is
Semax is a heptapeptide — seven amino acids — structurally related to a fragment of adrenocorticotropic hormone (ACTH), with a modification that improves stability compared with the natural fragment. It is produced synthetically and supplied lyophilised.
Why it is studied
Semax features in preclinical and in-vitro neuroscience literature as a tool compound. Conclusions belong to those studies; nothing here extends them to any human context.
Handling notes
- Supplied lyophilised; reconstitute gently without shaking.
- Store the dry solid sealed, cold and dark.
- Refrigerate after reconstitution and aliquot for repeated use.
