DHH-B is typically taken orally as a dietary supplement. It works by interacting with GABA receptors in the brain, which play a significant role in regulating mood and anxiety levels. This helps to enhance relaxation and reduce stress responses.
PE 22-28 is typically administered through injection in research settings. It works by interacting with neuropeptide Y (NPY) receptors, particularly Y2 receptors, in the brain. These receptors are associated with regulating emotional responses and stress adaptation.
