Retatrutide
Retaglutide is a new dipeptidyl peptidase-4 (DPP-4) inhibitor class hypoglycemic drug that can prevent the degradation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulin-releasing polypeptide (GIP) by DPP-4 enzyme in the intestine and blood, prolonging their activity, thereby promoting insulin secretion by pancreatic β cells without affecting the basal level of fasting insulin, while reducing the secretion of glucagon by pancreatic α cells, thereby more effectively controlling postprandial blood sugar. It performs well in terms of hypoglycemic effect, tolerance, and compliance.

Tirzepatide
Tirzepatide is a novel dual agonist of GIP and GLP-1 receptors, developed for the treatment of type 2 diabetes and obesity. As a first-in-class “twincretin,” Tirzepatide enhances insulin secretion, suppresses glucagon release, and significantly reduces appetite and body weight. Our high-purity Tirzepatide API is chemically synthesized, free of host-cell-derived impurities, and meets international regulatory standards for quality, stability, and scalability.
-
Semaglutide
Semaglutide is a long-acting GLP-1 receptor agonist used for the treatment of type 2 diabetes and chronic weight management. Our high-purity Semaglutide API is produced through chemical synthesis, free from host cell proteins and DNA residues, ensuring excellent biosafety and consistent quality. Compliant with FDA guidelines, our product meets stringent impurity limits and supports large-scale production.
