Dihexa
The Synaptogenic Peptide — Next-Level Cognitive Enhancement
01
Overview
Dihexa (N-hexanoic-Tyr-Ile-(6) aminohexanoic amide) is a potent cognitive enhancer developed at Washington State University. It is derived from angiotensin IV and has been shown in preclinical research to be approximately 10 million times more potent than BDNF at inducing new synapse formation — a process critical for learning and memory.
02
Mechanism of Action
Dihexa binds to hepatocyte growth factor (HGF) and facilitates its interaction with the MET receptor (c-Met), triggering downstream signaling cascades that promote dendritic spine formation and synaptogenesis. It bypasses the blood-brain barrier and operates at extremely low concentrations.
03
Research Highlights
Washington State University research showing 10M× greater potency than BDNF in synaptogenesis
Morris water maze studies show dramatic spatial memory improvement in aged animals
Research on Parkinson's and Alzheimer's models shows neuroprotective synaptogenic activity
04
Dosage
Administration & Timing
Oral administration (capsule or solution) or Subcutaneous (SC) injection into abdominal or gluteal subcutaneous tissue. Research protocols typically use once-daily oral administration; timing independent of food.
Dosage Guidelines
Cycle Length
2–4 weeks; longer protocols (8–12 weeks) documented in cognitive decline research.
05
Reconstitution
Solvent
Bacteriostatic Water (0.9% benzyl alcohol)
Volume
2 mL added to a 20 mg vial (for SC research)
Concentration
10 mg/mL
Storage
Lyophilized powder: store at -20 °C long-term. Reconstituted: refrigerate 2–8 °C, use within 30 days.
Notes
Dihexa is orders of magnitude more potent than BDNF in synaptogenesis assays. Use microgram-level precision in research dosing.
