Peptide Comparison

Cortexin vs Noopept

Q: What is the difference between Cortexin and Noopept?

Cortexin: Polypeptide bioregulator from bovine cortex; modulates neurotransmitter activity; activates GABA and dopamine systems; reduces excitotoxicity; stimulates neuronal repair Noopept: Prodrug converting to cycloprolylglycine; modulates AMPA and NMDA receptors; increases NGF and BDNF expression

Both are Neuro & Cognitive peptides.
