Cerebrolysin vs FGL
Well Studied vs Limited Research
compatible Both provide neurotrophic support through different pathways; no known adverse interactions.
Molecular Data
Cerebrolysin FGL
Weight Variable ~1500 Da
Half-life Minutes (component-dependent; e.g., BDNF ~10 min) Not well characterized
Chain Multiple peptides —
Type Purified porcine brain proteins Synthetic peptide derived from the second fibronectin type III module of NCAM
Key Benefits
Cerebrolysin
01 Direct brain delivery
02 Standardized dosing
03 Extensive clinical evidence
04 Ready-to-use formulation
05 Used clinically in 50+ countries
FGL
01 Activates FGFR1 to promote synaptic plasticity
02 Stimulates hippocampal neurogenesis
03 Provides neuroprotection against excitotoxic and ischemic injury
04 Enhances long-term potentiation (LTP) in preclinical models
05 Potential cognitive enhancement via NCAM-mimetic signaling
Dosing Protocols
Cerebrolysin
10-50mL depending on indication (stroke/TBI higher doses) / Once daily for acute conditions; 5 days weekly for chronic conditions
Small Volume IV Up to 10mL Once daily
Intramuscular Up to 5mL Once daily
Acute Stroke 20-50mL Once daily for 10-21 days
Traumatic Brain Injury 20-50mL Once daily for 7-30 days
Alzheimer's Disease 10-30mL 5 days weekly for 4 weeks
Vascular Dementia 10-30mL 5 days weekly for 4 weeks
FGL
100-200mcg per day / 1x daily
Cognitive support (research protocol) 100-200mcg 1x daily
Side Effects
Cerebrolysin

Possible mild dizziness or agitation in early treatment
FGL
Injection site reactions (redness, mild swelling, irritation)
Contraindications
Epilepsy
Severe renal insufficiency
History of severe allergic reactions to porcine products
Pregnancy or breastfeeding
Known peptide or NCAM-related compound allergies
Very limited human safety data -- use with caution under medical supervision
