- Dihexa
- HGF receptor agonist → BDNF upregulation
- 1–5mg/mL
- Daily
- Morning (6–10 AM)
- Best for learning and memory consolidation tasks; 7× more potent than BDNF in synaptogenesis studies
- Cerebrolysin
- NGF-mimetic neuropeptide blend
- Pre-mixed solution (no reconstitution)
- 5 days/week for 4 weeks
- Evening (before sleep)
- Clinically studied in stroke recovery; supports dendritic branching during sleep-phase consolidation
- P21
- CNTF-derived neuroprotective peptide
- 2–3mg/mL
- Every 48–72 hours
- Morning or evening (flexible)
- Longer half-life reduces injection frequency; crosses BBB efficiently; minimal receptor desensitisation
- Semax
- Melanocortin receptor modulator
- 0.5–1mg/mL
- Morning (pre-cognitive tasks)
- Rapid onset (30–60 min); dopaminergic modulation without neurotrophic growth—different mechanism class
