P21 versus Dihexa
Dihexa is sometimes mentioned alongside P21 as a cognitive enhancement peptide. Dihexa works through hepatocyte growth factor and its receptor c-Met, promoting synaptogenesis and dendritic branching. It has been described as being millions of times more potent

- Dihexa is sometimes mentioned alongside P21 as a cognitive enhancement peptide. Dihexa works through hepatocyte growth factor and its receptor c-Met, promoting synaptogenesis and dendritic branching. It has been described as being millions of times more potent than BDNF at promoting synaptic connections, though this comparison requires context as the peptides work through entirely different mechanisms. Where P21 focuses on growing new neurons, Dihexa focuses on strengthening connections between existing ones.
