Langfang Jiwei Medical Technology Co., Ltd. is located in Guangyang District, Langfang City, close to Beijing. We are a professional high-tech enterprise dedicated to biomedical fields, focusing on the R&D, production, sales and technical support of polypeptide products. Our main offerings cover a diversified range of high-quality products, including medical devices, disposable syringes, pharmaceutical raw materials, fine chemicals, synthetic polypeptides, beauty skincare goods and hypoglycemic health products. Each product category follows standardized production specifications and rigorous quality inspection standards to ensure consistent and reliable performance for global buyers. In terms of medical devices and disposable syringes, we supply sterile single-use syringes with excellent airtightness, smooth pushing performance and zero liquid leakage. These medical-grade consumables are produced in dust-free purification workshops, complying with international medical safety standards, and are widely used in clinical treatment, medical injection and daily medical protection scenarios. For pharmaceutical raw materials and fine chemicals, we provide high-purity pharmaceutical intermediates, bulk chemical raw materials and customized fine chemical products. Featuring low impurity concentration, stable physical and chemical properties as well as great biocompatibility, these chemical materials are perfectly suitable for pharmaceutical synthesis, biochemical research and industrial precision processing. Our synthetic polypeptide series consists of mainstream high-demand products, namely Retatrutide, Semaglutide, GHK-CU and NAD. Adopting advanced solid-phase synthesis and high-purity purification technologies, all polypeptide products boast stable molecular structure, high purity and easy absorption. Among them, Retatrutide and Semaglutide are well recognized for reliable blood sugar regulation and weight management effects; GHK-CU serves as an effective skincare polypeptide for anti-oxidation, skin repair and anti-aging; high-activity NAD is widely applied in anti-aging healthcare and biological research. Additionally, our beauty and hypoglycemic health products are formulated with natural mild raw materials and high-efficiency polypeptide ingredients. The skincare products focus on moisturizing, anti-wrinkle, antioxidant and skin barrier repair, while hypoglycemic health supplements can gently assist blood sugar stabilization without side effects, catering to the healthcare demands of hyperglycemic groups. Equipped with strong R&D capabilities and mature synthesis technology, we maintain long-term stable cooperation with overseas enterprises and professional research institutions. We have built a complete quality control system covering raw material screening, production processing and finished product testing to strictly control every production link.
