But where semaglutide acts on one receptor (the glucagon-like peptide-1, or GLP-1, receptor), and tirzepatide on two (GLP-1 and the gastric inhibitory polypeptide, or GIP, receptors), retatrutide has been nicknamed Triple G for its ability to work on three hormone receptors (those for GLP-1 and GIP, as well as the glucagon, or GCG, receptor)
GLP1 Wegovy (semaglutide) and GIP Mounjaro (tirzepatide) are prescription-only in the UK
"Many cases require prior authorization or are not covered, and out-of-pocket costs generally range from a few hundred dollars for targeted panels to $1,000 to $2,000 for broader panels and several thousand dollars for whole exome or genome sequencing," says Dr
