I purchased Pro Performance AMP Amplified Gold Whey 100% Protein Vanilla Ice Cream Flavor (891g) from a GNC store in Robinson Bacolod. It was on sale for 1,700 PHP (32 USD) from its 3,300 PHP original retail price because, as the saleslady explained, it was a new product the company is promoting. When I opened it at home, my wife and I were bothered by a foul smell that came out of the container and a rotten milk/egg like smell filled the house. At first, we thought that the smell was strong because the product was new and we just opened the sealed container. The following day we prepared two servings after our workout at the gym, although the smell was still strong compared to other whey protein products we previously consumed. As soon we drank it, we felt uncomfortable and both the smell and the taste were nauseating and made us feel rather sick in the stomach. We questioned if this how the product is supposed to taste or it is perhaps damaged. The next day I decided to try it again; my wife didn't have the stomach for it anymore. I prepared a serving with a colder water this time and the result was the same, nausea and feeling of disgust. We brought the container back to GNC Robinson and explained our concern. We asked to exchange it with another flavor or product that is less strong in taste and smell and more tolerable to consume. I also brought the plastic shaker I used for preparing the drink, which I already washed twice. I opened the cover of the shaker and had two staff smell it. They agreed that it was, as we described, disgusting! The foul smell had also filled up the store upon opening the container. After a long wait at the store for the management in Manila to receive our complaint and make their decision, we were asked to wait for a day before we receive the reply. We left the product with the store manager for testing as she requested and left. The following day, I received a text message from the manager saying: "Good afternoon, Sir. Sorry to tell you that we cannot give a replacement of your whey protein upon the decision of our head office. Thank you for your kind understanding." I replied thanking her for the updates and informing her that they can keep the container. We were disappointed and opted not to bring such nauseating and malodorous product back home, and to let the store deal with disposing it rather than us. After all, we lost the money we paid and the time we spent going back and forth to the store and waiting for managerial decisions. For the past many years, we have enjoyed the quality, taste and benefits of pure protein shakes from different companies and at lower cost. We learned a valued lesson: To shop somewhere else and to not fall again for GNC's persuasive sales schemes.
