- Cerebrolysin
- Mimics NGF/BDNF; increases acetylcholine release from cholinergic neurons
- 2–4 hours (acute); cumulative after 10+ sessions
- 30ml IV infusion daily × 10–20 days
- Crosses via neurotrophic factor receptors
- Strongest acute cholinergic effect; requires IV administration
- Dihexa
- Potentiates HGF/c-Met signaling; upregulates BDNF-driven synaptogenesis
- 10–14 days (chronic neuroplasticity)
- 2–5mg subcutaneous daily
- Yes. Passive diffusion due to small size
- Best for sustained synapse formation; slow onset
- P21
- Enhances CREB phosphorylation; amplifies LTP in hippocampus
- 3–5 administrations (subacute)
- 1mg intranasal or subcutaneous every 48 hours
- Yes. Intranasal route bypasses BBB via olfactory pathway
- Targets memory consolidation specifically; best for learning protocols
- MK-677
- Stimulates pulsatile GH release; increases serum IGF-1
- 7–10 days (indirect CNS support via IGF-1)
- 10–25mg oral once daily
- IGF-1 crosses via insulin-like growth factor receptors
- Orally bioavailable; indirect cognitive support through sleep and IGF-1 elevation
