Can peptides help you lose weight?

It depends on which one. Semaglutide, tirzepatide, and liraglutide are FDA approved for weight loss, based on large, careful studies in people. Retatrutide, cagrilintide, and survodutide are still-experimental drugs from the same family (they act on GLP-1 and glucagon, two gut and blood-sugar hormones), and they show similar results in studies. AOD-9604 was sold for years as a fat-loss peptide. In its own obesity study in people, it did no better than a dummy pill. What decides whether a peptide works is what it acts on, not the word peptide.
