I bought vitamins at the store and got them. The first thing that caught my eye was the engraving on the bottom of the jar, which was not of high quality in comparison with Men vitamins, the letters were faintly visible. There was no QR code near the barcode, as they explained to me on the phone, "This happens," and some story about the fact that they receive protein in identical packages of different flavors. After opening the jar, I saw that there was no cotton wool or silica gel inside, the mandatory packaging elements from Optimum Nutrition (according to those.Optimum Nutrition support by e-mail), which gives the impression that I purchased a fake. When asked to explain this action, they were sent to make an examination for their own money. Why should I waste my time and money to make sure 10,000% that this is a fake? I left a review on the site - they wrote that it will be added after passing moderation. After 2 days, the review did not appear, apparently no one is interested in negative reviews in this office. I do not recommend it.
