I bought it from that ss-shou website, claiming to be official website. After I bought it, I found that the packaging was not normal at all, and then I checked it carefully. It belongs to the old medicine in new packaging. This medicine has long been exposed as an illegal product. I contacted customer service to ask for a refund, but I ignored it. The key is that the above anti-counterfeiting can't be found in the website phone or SMS, so it is not recommended that you buy it!
