FGL-L
THE SYNAPSE ENHANCER
Neural Cell Adhesion Molecule-derived FGL peptide
FGL-L is a synthetic peptide that mimics neural cell adhesion molecule (NCAM), a protein crucial for brain cell communication and plasticity. It activates growth factor receptors to promote synapse formation, enhance memory, and protect neurons.
