What is the difference between Cortexin and Pinealon?

Cortexin: Polypeptide bioregulator from bovine cortex; modulates neurotransmitter activity; activates GABA and dopamine systems; reduces excitotoxicity; stimulates neuronal repair Pinealon: Glu-Asp-Arg tripeptide; penetrates blood-brain barrier; modulates gene expression in neurons; reduces oxidative stress in brain tissue

Is Cortexin FDA approved?

Cortexin is not evaluated or approved by the FDA. It is discussed for research and educational purposes only, not as medical guidance.

Is Pinealon FDA approved?
