1, Chengdu Rong Sheng Pharmaceutical Co., Ltd. (Chengdu High-tech Zone)
2. Hualan Bioengineering Co., Ltd. (Hualan Avenue, Xinxiang City, Henan Province)
3. Shanghai Laishi Blood Products Co., Ltd. (Minhang District, Shanghai)
4. Green Cross (China) Biological Products Co., Ltd. (Huainan Economic and Technological Development Zone)
Geographically (note: there is no sense of regional discrimination), to be honest, Shanghai has the highest development and technical level of bio-industry in China. From this point of view, Shanghai Lai Shi should be good, while Hualan Bio is a listed company with production workshops in Jiangsu, Zhejiang and North China, with strong strength and guaranteed quality.
Of course, the above is only a superficial analysis. As a biological agent, each batch of drugs needs to be tested according to national regulations. From this point of view, the drugs of various manufacturers are in line with national standards, and the safety of drug use is guaranteed.
