Intravenous, Intramuscular injection

Overview

A porcine brain-derived peptide preparation consisting of low-molecular-weight neuropeptides and free amino acids that mimic the action of endogenous neurotrophic factors. Cerebrolysin exhibits neurotrophic activity similar to BDNF, GDNF, and CNTF, promoting neuronal survival, synaptic plasticity, and neurogenesis.

Mechanism of Action

It modulates GSK-3beta, CDK5, and calcineurin-NFAT signaling cascades involved in neurodegeneration.

Research Summary & Key Findings

Approved in over 50 countries (not FDA-approved) for stroke, traumatic brain injury, and Alzheimer's disease. A meta-analysis of clinical trials showed modest improvements in global clinical function in Alzheimer's patients (Gauthier et al., Dement Geriatr Cogn Disord, 2015). The CASTA trial in acute ischemic stroke showed improved outcomes at 90 days. Safety concerns regarding prion transmission from porcine brain tissue have been raised but not substantiated.

Clinical Status

Investigational

Cerebrolysin is in the investigational stage. While preclinical and early-phase data exist, it has not received regulatory approval for clinical use in the United States.

No lawful pathway today

Cerebrolysin is not FDA-approved and does not currently have a lawful prescription or compounding pathway in the United States, so there is nothing for us to sell you here and no consultation to book. That can change: eight peptides moved back to a lawful pathway in February 2026.
