Where is the sales point of Niubao OB protein Tangshan?

Online shopping, An 'an Mall, I ate very well. I bought it on Taobao last time. It's very cheap, but it's useless. It is suspected to be fake, so I suggest you check the website. I took it twice, the first time I lost more than 40 kilograms in two months, and the second time I took the medicine for three months, I lost more than 20 kilograms. I bought it on Taobao later, and it's still the same. rabid
