Scientific interest centers on its role as a long-acting GHRH-receptor agonist for investigating GH/IGF-1 axis regulation and lipid/adipose metabolism in preclinical systems, and on the comparative pharmacology of stabilized GRF analogs. Research applications Long-acting GHRH-receptor agonist for axis-signaling studies Tool compound in adipose/metabolic pathway research linked to GH signaling Comparator in structure-activity studies of N-terminally modified GRF peptides Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
