GLP-1 (Glucagon-Like Peptide-1, residues 7-36 amide) is a gut-derived incretin hormone that potently stimulates glucose-dependent insulin secretion and suppresses glucagon release, making it a fundamental tool in metabolic research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. GLP-1 is investigated in research on insulin secretion, glucose homeostasis, appetite regulation and pancreatic beta-cell function, and is widely applied in cell-based assays, receptor studies and preclinical metabolic experiments. The freeze-dried form ensures good stability and convenient reconstitution, supporting reproducible experimental dosing. All batches undergo rigorous quality testing and batch-specific COA documentation can be provided on request. Store unopened vials sealed at 2-8 degree C, away from light and humidity; for longer preservation store at -20 degree C without repeated freeze-thaw cycles. Trial orders and bulk supply are supported, with OEM, private-label and secure neutral packaging available for global delivery. For research use only.
