Long-term Storage Conditions
CCK-4 acts primarily in the brain as an anxiogenic. It is commonly used in scientific research to induce panic attacks for the purpose of testing new anxiolytic drugs.
Cholecystokinin tetrapeptide (CCK-4, also PTK7) is a peptide fragment derived from the larger peptide hormone cholecystokinin. CCK-4 acts primarily in the brain as an anxiogenic, although it does retain some GI effects, but not as much as CCK-8 or the full length polypeptide CCK-58.
