Peptide Comparison

Cerebrolysin vs Dihexa

Q: What is the difference between Cerebrolysin and Dihexa?

Cerebrolysin: Standardized mixture of neuropeptides derived from porcine brain proteins; mimics endogenous neurotrophic factors (BDNF, NGF, CNTF); promotes neurogenesis and synaptic plasticity Dihexa: HGF/MET receptor potentiator; promotes new synapse formation; estimated 7 orders of magnitude more potent than BDNF in synaptogenesis models

Both are Neuro & Cognitive peptides.
