Peptides for Cognitive & Neuroprotective Research Semax · Selank · Dihexa · Neuropeptide Research · BDNF/NGF Upregulation · ≥99% HPLC · Janoshik COA
Cognitive and neuroprotective peptide research spans ACTH/MC4R pathway modulation (Semax, NA-Semax Amidate), GABAergic anxiolytic research (Selank), HGF/MET activation (Dihexa — reported million-fold more potent than BDNF), and neurotrophic signaling (Cerebrolysin, Semax, Dihexa). QSC stocks the complete neuropeptide catalog at ≥99% HPLC with Janoshik independent COA.
Cognitive and neuroprotective peptide research centers on Semax/NA-Semax Amidate (ACTH analogue, BDNF/NGF upregulator), Selank (GABA-A modulator, anxiolytic research), Dihexa (HGF/MET activation, synaptogenesis), Cerebrolysin (multi-neurotrophic), and Pinealon (Khavinson epigenetic bioregulator). QSC stocks all at ≥99% HPLC with Janoshik COA. Research use only.
What is Semax?
Semax is a synthetic heptapeptide analogue of the ACTH 4-10 fragment, studied for its effects on MC4R signaling, BDNF and NGF upregulation, and neuroprotection in preclinical models. It is widely used in Russian clinical and preclinical research. QSC stocks Semax and the enhanced NA-Semax Amidate form. Research use only.
What is Dihexa?
Dihexa is a synthetic peptide derived from Angiotensin IV, studied as an activator of the HGF/MET signaling pathway and PNP (purine nucleoside phosphorylase) inhibitor. Preclinical research suggests synaptogenic activity reported as orders of magnitude greater than BDNF in certain model systems. QSC stocks Dihexa at ≥99% HPLC with Janoshik COA. Research use only.
What is the difference between Semax and Selank?
Semax (ACTH 4-10 analogue) primarily modulates MC4R signaling and upregulates BDNF/NGF — studied for cognitive enhancement and neuroprotection. Selank (tuftsin analogue) primarily modulates GABA-A receptor and stabilizes enkephalin degradation — studied for anxiolytic effects with zero reported dependence in preclinical models. Complementary research mechanisms.
