Dear Mr. Shui, How are you ? I'm Azwar Farid from Indonesia. I need some information about Duo Cotexin. Does your company produce it ? If so, could you inform me the price ? I plan to visit China in the 1st week of December 2007, if everything meets our needs, i will visit your company to buy and hand carry it. I need the info as soon as possible. Looking forward to hearing from you soon. Thank you, Best Regards, Azwar Farid
