Cognitive & Focus & Mood

What labs study it for

Brain-chemistry research. Neuroscience labs use it, mostly in rodent models, to study BDNF (a protein that supports nerve cells) and brain messengers such as dopamine and serotonin.

What this compound is

Semax is a synthetic peptide of seven amino acids. Its first four residues copy a fragment of adrenocorticotropic hormone that has no hormonal activity on its own, joined to a proline-glycine-proline tail added to slow enzymatic breakdown. Neuroscience laboratories use it as a tool for studying brain-derived neurotrophic factor and monoamine signalling, largely in rodent models. Semax is licensed for clinical use in Russia; it has not been approved by the FDA or the EMA and is supplied here solely as a laboratory reagent.

Chemical description

Semax. Supplied lyophilized. Lot-specific HPLC and MS documentation accompanies each unit.

What labs study it for

Brain-chemistry and behaviour research. Labs use it in rodent studies of GABA (the brain's main calming messenger) and other brain-signalling systems.

What this compound is

Selank is a synthetic peptide of seven amino acids. It joins the sequence of tuftsin, a short fragment of an antibody molecule, to the same proline-glycine-proline tail used in Semax to slow enzymatic breakdown. Laboratories use it in rodent behavioural and neurochemical studies, particularly of GABAergic and monoamine signalling. Like Semax it comes from Russian research and is licensed for clinical use there; it has not been approved by the FDA or the EMA.
