Cerebrolysin
Cognitive · Neurotrophic peptide mix
Tier C
What this is
Manufactured by EVER Neuro Pharma in Unterach Austria via enzymatic proteolysis of porcine brain proteins — composition is a defined mixture of low-MW peptides and free amino acids but not fully reductionist ("defined biologic" vs single-compound contrast matters for QC). **Industry-funding caveat is central**: Cochrane reviews across three decades have consistently flagged that EVER Pharma sponsored or supplied study materials, randomization codes, and statisticians for most pivotal trials. **2023 Cochrane stroke review** (Ziganshina) concluded current RCT data do NOT support routine use AND found a 2.4-fold increase in non-fatal serious AEs across pooled trials — newest and most clinically important development since the entry was first written. **2019 Cochrane vascular dementia review** (Cui): modest cognitive benefit on MMSE and ADAS-cog+ across 6 RCTs n=597; no new RCTs eligible since — the field has stagnated. **CAPTAIN I-II TBI meta-analysis** (Poon 2021): small-to-medium effect at Day 30 and 90 in n=185 moderate-severe TBI; encouraging but small and manufacturer-sponsored. **2025 Patel MA** (Cureus August 2025) in n=2884 across 14 stroke RCTs reports positive early-recovery effect but does NOT escape the industry-funding overlap with Cochrane's source data. Biohacker take: real pharmacology and decades of EU/Asia clinical use, but the evidence base is durably weakened by industry funding, the multi-component biologic is hard to QC outside of manufacturer-supplied product, and the 2023 Cochrane non-fatal SAE signal is a new and underappreciated concern. Use only manufacturer-supplied product if at all — gray-market "Cerebrolysin" in research-chemical channels is uncharacterized.
Mechanism
Porcine brain-derived preparation of low-molecular-weight peptides and free amino acids produced by standardized enzymatic proteolysis (EVER Neuro Pharma; Unterach Austria); mimics endogenous neurotrophic factors with BDNF-like activity; multi-component biologic — defined mixture but not fully characterized vs single-compound drugs; used widely in EU/Russia/China/Korea/Asia for stroke; vascular dementia; and TBI
Dose & route
10-30 mL IV or 5-10 mL IM daily for 10-21 day courses; multiple courses per year in chronic indications
