Frequently asked questions

Which weight loss & glp-1 peptides are FDA-approved?

5 of the 18 have an FDA-approved product: L-carnitine, Liraglutide, Semaglutide, Tesamorelin and Tirzepatide. Research-grade vials sold online are not those approved products.

Which weight loss & glp-1 peptides have the most research?

By PubMed records: Semaglutide (5,707), Liraglutide (5,683) and Tirzepatide (2,637). 5 have fewer than 25 indexed papers, mostly cell or animal work.

Which have registered human trials?

11 appear on ClinicalTrials.gov, led by Semaglutide (788), Liraglutide (515), L-carnitine (313) and Tirzepatide (303). Cagrilintide, Cagrilintide + semaglutide, Mazdutide, O-304, Retatrutide, Survodutide and Tesofensine are still investigational.
