Dihexa vs Other Nootropic Peptides: HGF Pathway Comparison
Dihexa HGF mimetic (allosteric c-Met modulation) Yes. Partial agonist 48–72 hours Memory consolidation, spatial learning Most potent per-dose nootropic peptide documented; requires precise interval management to prevent receptor saturation P21 CREB phosphoryla

- Dihexa
- HGF mimetic (allosteric c-Met modulation)
- Yes. Partial agonist
- 48–72 hours
- Memory consolidation, spatial learning
- Most potent per-dose nootropic peptide documented; requires precise interval management to prevent receptor saturation
- P21
- CREB phosphorylation (BDNF-independent)
- No
- 24–48 hours
- Memory formation, neuronal survival
- Complements Dihexa through orthogonal pathway; no receptor competition when co-administered
- Cerebrolysin
- Neurotrophic factor cocktail (BDNF, NGF, CNTF)
- Indirect (via endogenous HGF upregulation)
- Daily
- Stroke recovery, age-related decline
- Broader spectrum but less receptor-specific; useful for models with compromised endogenous neurotrophin production
- Semax
- BDNF/NGF upregulation
- Attention, stress resilience
- No direct HGF pathway engagement; safe to combine with Dihexa at standard intervals
