Keshan is quite stiff. Can it still be used without freezing?

I can't. According to the information released by Dr. official website, it can be known that Keshan can't be frozen or not, but it can't be exposed to the sun or frozen. If it is lower than 0 degrees Celsius, it will lose its biological activity and cause allergic reaction. Keshanting is a trade name, and its general name is Skochizumab injection. This product needs to be used for a long time, and it can be stopped after the condition is obviously improved.
