Semax
Also known as: ACTH(4-10) analog · Nootropic peptide
A synthetic analog of a fragment of ACTH, studied for neuroprotection, focus and cognitive performance.
Semax is a synthetic peptide based on a fragment (positions 4–10) of adrenocorticotropic hormone (ACTH), stabilised with a proline-glycine-proline tail so it resists rapid breakdown.
Its research literature centres on neuroprotection and cognition: modulation of BDNF and nerve growth factor, dopaminergic and serotonergic signalling, and effects studied in the context of focus, memory and recovery from neurological stress.
Semax and Selank are the two best-known Russian regulatory peptides and are often studied as a pair. Supplied for research purposes only, HPLC-verified with a Certificate of Analysis.

Nootropic
A substance studied for supporting cognition — focus, memory, clarity — often via neurotrophic or neuroprotective pathways.
Analog
A peptide deliberately modified from a natural sequence to improve stability, selectivity or potency.
Peptide Bond
The covalent amide bond linking amino acids into a peptide chain — the defining structural feature of every peptide.
Reconstitution
The process of dissolving a lyophilised (freeze-dried) peptide in a sterile solvent such as bacteriostatic water before study.
