Dihexa
THE MEMORY AMPLIFIER
DiHexa; PNB-0408; N-hexanoic-Tyr-Ile-(6)-amino-hexanoic amide
Dihexa is a synthetic peptide derived from angiotensin IV that's shown unusually strong synapse-forming activity in preclinical studies. It activates the HGF/c-Met pathway, the same system that helps your brain repair itself, and does so millions of times more potently than BDNF. It promotes new synapse formation and may help with Alzheimer's and Parkinson's.
