QSC RESEARCH COMPOUND GUIDE
BDNF/TrkBFGFR1HGF/METNeuroplasticity
Cognitive research encompasses neuroplasticity, neuroprotection, BDNF signalling, synaptogenesis, and neurotransmitter modulation. QSC supplies peptides across multiple distinct neurological mechanisms — from BDNF/TrkB (semax) to FGFR1 (PE-22-28) to HGF/MET (dihexa) — each targeting independent aspects of cognitive neuroscience research.
What is the difference between Semax, Dihexa, and PE-22-28 for cognitive research?
Semax activates BDNF/TrkB via ACTH receptor pathway. Dihexa is an HGF/MET superagonist (synaptogenesis). PE-22-28 activates FGFR1 independently of BDNF/TrkB. All three promote synaptogenesis/neuroplasticity through completely independent receptor pathways — making them combinable for mechanistic dissection.
What is the research value of PE-22-28 for antidepressant research?
PE-22-28 is uniquely valuable because it produces antidepressant-like effects (forced swim test) through FGFR1 — entirely independent of BDNF/TrkB, serotonin, GABA, or monoamine pathways. This makes it the primary tool for studying whether FGFR1 activation alone is sufficient for neuroplastic antidepressant effects.
How do sleep peptides relate to cognitive research?
Sleep architecture (particularly delta/SWS sleep) is essential for memory consolidation, synaptic pruning, and glymphatic clearance of metabolic waste. DSIP and epitalon improve sleep quality — affecting cognitive endpoints as a downstream mechanism. VIP VPAC2/SCN research directly addresses circadian gating of memory consolidation.
What formats does QSC supply cognitive research peptides in?
Lyophilised research vials, ≥99% HPLC purity, Janoshik COA. See reconstitution calculator. Ships from domestic warehouses in USA, EU, UK, Canada, and Australia.
