To differentiate between the fake and original Nutrabay whey protein

There must be an importer sticker or importer details printed on the label of the imported products.

The product provided should have a proper expiry date and batch number printed on it.

The seller should always provide the buyer with tax paid retail invoice.

The seller should be actively certified with the brand in order to import or sell the product.

Thus look for the certification or if not seen then ask for one, if they are genuine they would not get offended but would show you the certificate and would respect you for checking things before buying.

Hope this things made somewhat picture clear in your mind about the product.
