Semaglutide is a synthetic GLP-1 (glucagon-like peptide-1) receptor agonist and one of the most extensively studied metabolic peptides in preclinical research. Its high receptor binding affinity and extended half-life profile make it a reference compound for investigating GLP-1 signalling pathways, glucose-dependent insulin secretion, and central appetite regulation mechanisms. Available in 15mg vial. Every batch is HPLC tested and independently verified to a minimum of 99% purity. Certificate of Analysis available on request.
