Bests & Worsts Reviews from Amazon

I use this product all of the time. Sometimes I buy it from Amazon and sometimes GNC. I just received a large bottle of watermelon. It was NOT the same product. The consistancy, smell, and taste were wrong. It smelled like it had baking powder in it. It didn't have the normal fruity smell. The taste was off. I only took a small sip but it didn't taste the same. I knew fake products are out there but this was the first time I had one. I'm returning it immediately.
