I have been buying celsius energy drinks in the can at my local grocery store. It is great product,does give you energy ,keeps me going as a bar manager I need all energy I can get on my double shifts. I was very happy to discover that they do come in the powdered form and to go packets,makes my life easier and more affordable too,to buy it this way. Average brand name energy drinks are loaded with toxic stuff,like artificial colors, flavors,loaded with sugar or artificial sweeteners...etc Thankfully celsius berry is not,that is another reason why I love it. Highly recommend it to keep you going or extra energy for working out !
