7 Best Peptides for Alzheimer's
When people search for the best peptides for Alzheimer's, they most often encounter Cerebrolysin, Semax, and Selank as the starting point. From there, the conversation extends to investigational compounds: Dihexa, a synaptogenesis-promoting peptide studied in animals; PHDP5, a tau-targeting peptide that released a key transport protein in mouse studies; the CDK5-blocking peptide, a 12-amino-acid synthetic molecule designed to interrupt a hyperactive enzyme that drives neuron damage; and Semaglutide, a GLP-1 hormone approved for diabetes that some researchers associate with reduced Alzheimer's risk. People reach for these compounds because they address real biological targets in the disease, from neurotrophic support to synaptic repair to neuroinflammation. This guide walks through all seven: what each one is, how people use it for cognitive decline, and what the evidence honestly shows. The compounds are ordered by how prominently each appears in research and real-world use, not ranked as a personal recommendation, and the personalized decision belongs in the MyPeptidePal app.
