Hello, 
I'm Adien, a university student who is working on a thesis. I'd like to ask for the latest price and the specifications of this product since I will be using Acyclovir for my research. I need 100 grams of Acyclovir, can I purchase this product with that amount of weight? Also, I need the product with long period of expired date, I need for at least until 2027. I'd like to ask for the Certificate of Analysis too, will I get that if I purchase this product on your company? And if I have China address, how much the shipping cost? Thank you. 

Best Regards,
Adien
