Optimum Nutrition Gold Standard 100% Whey Protein2.27 kg, Double Rich Chocolate

I bought protein and it was open I asked the shipper he said it is flip card packing and original it was like refilled

I will buy if its genuine product plz give me some proof if its genuine

Guys, please don't waste your money on this seller. The container arrived in dust which had to be shrugged off. On opening the box, I found that the date of import and serial number were torn apart. Rest all seemed to be genuine. As soon as I opened the seal, I had to, how would I know otherwise it was fake, I was surprised. It was nothing but choona "limestone" mixed with a brown color. I was so sad, cried internally, enraged upon being deceived. I called Flipkart immediately, they said they couldn't return this product and told me to get a lab certification to prove it was fake from an optimum nutrition lab (which is in USA). How could one be such a retard? This seller has no contact no. / email to be in touch with. I wasted 6300/- on this one. Please don't make this mistake guys :(
