I have been a customer of Hs biopharmaceuticals, inc for several years now and I must say, their products are of excellent quality. The chondroitin sulfate I purchased from them has greatly helped with my joint pain. Their website, chondroitinsulfate.com.cn, is user-friendly and easy to navigate. I highly recommend Hs biopharmaceuticals, inc.
