Cerebrolysin
Summary
Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.

Variable for the complex; individual peptide fractions: minutes to hours
Admin Route
Oral, Topical
IV, IM
Research
Typical Dose
1,000–2,000 mg
5–10 mL
Frequency
Once to twice daily with meals
Daily for 10–20 days
Key Benefits
  • Potent anti-glycation (prevents protein cross-linking/aging)
  • Broad-spectrum antioxidant in muscle and brain
  • Extends cell lifespan and protects telomeres

  • Neuroprotective against Alzheimer's amyloid-beta
  • Wound healing acceleration
  • Anti-cataract properties (eye health)
  • Improves diabetes complications via AGE prevention
  • Chelates excess copper and zinc
  • Promotes neurogenesis and synaptic plasticity
  • Approved for stroke rehabilitation (accelerates recovery)
  • Alzheimer's disease: slows progression and improves cognition
  • Traumatic brain injury recovery
  • Enhances memory and executive function
  • Neuroprotection against oxidative stress and excitotoxicity
  • Anti-amyloid and anti-tau effects
