What is Dihexa (High-Dose)??

Dihexa (PNB-0408, CAS 1239264-98-2) is a highly CNS-penetrant HGF/MET-potentiating peptidomimetic that drives de novo synaptogenesis — estimated at 10⁷-fold greater potency than BDNF for new dendritic spine formation. This 10mg/vial high-dose format supports dose-escalation protocols, multi-cohort neurodegeneration studies, transdermal delivery experiments, and long-duration cognitive paradigms where larger quantities per session are required. Molecular formula C₂₄H₃₉N₃O₄, MW 437.58 g/mol.

Research Applications

High-Dose Synaptogenesis

Dose-escalation dendritic spine density, concentration-response at HGF/MET receptor

Extended Cognitive Studies

Multi-week spatial learning, fear conditioning, and NOR paradigms requiring higher peptide reserves

Transdermal Delivery Research

Lipophilicity-driven skin penetration studies, bioavailability comparison vs. sc/ip routes

Neurodegeneration Reversal

High-dose Alzheimer’s-model synapse recovery, AChE-lesion and Aβ model synaptogenesis restoration

Neuroplasticity Mechanisms

LTP, AMPA/NMDA receptor trafficking, PSD-95 clustering under sustained HGF/MET activation

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
