Dihexa vs Methylene Blue
A side-by-side research comparison of Dihexa and Methylene Blue across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Dihexa | Methylene Blue |
|---|---|---|
| Full name | Dihexa (N-hexanoic-Tyr-Ile-(6)-aminohexanoic amide) | Methylene Blue (Methylthioninium Chloride) |
| Category | Cognitive & Nootropic | Cognitive & Nootropic |
| Status | Research compound | FDA-approved (off-label use) |
| Mechanism | Allosteric potentiator of HGF/c-Met signaling driving synaptogenesis, dendritic spine formation, and neuronal survival in hippocampal circuits. | Acts as an alternative electron carrier in the mitochondrial electron transport chain, bypassing complex I-III blockades. Inhibits monoamine oxidase, tau aggregation, and provides antioxidant protection through auto-oxidation cycling. |
| Molecular weight | 507.6 Da | 319.85 Da |
| Half-life | 6-12 hours | 5-6.5 hours |
| Bioavailability | Moderate (oral/SubQ) | ~72% oral |
| Typical dose | 10-20 mg (oral) or 2-5 mg (SubQ) | 0.5-2 mg/kg |
| Frequency | Daily | Daily or cycled |
| Route | Oral or Subcutaneous | Oral solution or sublingual |
