Cerebrolysin
Cerebrolysin is a porcine brain-derived peptide mixture used for neuroprotection and cognitive support. People typically run it at 500 mcg/day, though dosing schedules are often unspecified. The off-label evidence base is thinner than commonly suggested, with most exploratory indications lacking posted results, and community discussion notes variable individual response and recurring injection-site reactions.
Research Evidence
Evidence shape
Clinical evidence for Cerebrolysin sits at a moderate tier, with the strongest data coming from Phase 3 trials that showed modest improvements in Alzheimer disease (≈‑0.6 points) and acute cerebral stroke treated within 12 hours (≈+1.0 units). The research portfolio covers 28 distinct neurological indications, backed by 12 sponsors and three blinded studies that have posted results, while the remaining trials are largely exploratory, single‑trial or still recruiting. The lack of published outcomes for most indications signals that robust evidence is limited to the few reported endpoints.
