Cognitive and Neurological Research Peptides
Research into peptide-mediated effects on cognition, neuroinflammation, anxiety, and neuroprotection has produced a growing body of preclinical literature. Three compounds with the most substantial published bases in this area are Selank, Semax, and KPV — each acting through distinct but complementary neurological pathways.
Selank is a synthetic heptapeptide derived from tuftsin (Thr-Lys-Pro-Arg-Gly-Pro-Gly), an endogenous immunomodulatory peptide. Russian research groups have studied its effects on GABA-A receptor modulation, BDNF expression, and anxiety-like behaviours in rodent models. Semax is an ACTH(4-7)-Pro-Gly-Pro analogue developed for neuroprotection research, with studies examining its effects on BDNF upregulation, stroke recovery, and cognitive task performance in animal models. KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-MSH, studied for its anti-inflammatory properties via NF-kB inhibition and melanocortin receptor signalling in intestinal, dermal, and neurological inflammation models.
All three compounds are supplied for qualified laboratory research use only. For research use only.

Frequently Asked Questions
What peptides are used in cognitive research in Australia?
Selank, Semax, and KPV have the most substantial published bases in cognitive and neurological research. Selank is studied for anxiolytic effects; Semax for neuroprotection and cognition; KPV for anti-neuroinflammatory properties. All are available wholesale from Eternal Peptides Wholesale. For laboratory research use only.
What is the difference between Selank and Semax?
Selank is a tuftsin analogue studied primarily for anxiolytic effects via GABA-A modulation and BDNF expression. Semax is an ACTH-derived peptide studied for neuroprotection, cognitive enhancement, and BDNF upregulation. They act on different primary pathways and are frequently studied in separate research contexts. For research use only.
What is KPV peptide used for in research?
KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-MSH. Research has investigated its anti-inflammatory and antimicrobial properties via melanocortin receptor pathways and NF-kB inhibition, particularly in models of intestinal inflammation, skin inflammation, and neuroinflammation. For research use only.
