Previous studies that explored the effects of larger peptide GLP-1s such as semaglutide in the brain have found that they suppress hunger-driven eating by engaging networks in the hypothalamus and hindbrain
This makes it one of the smaller bioactive peptides, far shorter than compounds like BPC-157 (15 amino acids) or GHK-Cu (3 amino acids plus copper ion)
By mimicking a hormone called GLP-1, the medicines suppress hunger and make us feel fuller longer
