How is the effect of Guo Xin capsule? My mother bought more than 4000, I wonder if it's a lie?
I went to official website to have a look, and the customer service staff all said that they didn't understand how to prove that Professor Zhao invented this medicine, and they didn't dare to say anything with a guilty conscience, so don't believe anything they said, how dare you cheat! ! ! These heartless bastards, I hope your mother will buy more medicines from regular channels and not be cheated again.
