I’m very skeptical about energy drinks and picky about pre-workout drinks. Some have only given me energy for a short time, some give me a crash, and some give me bad reactions such as shakes or the prickly feeling. But I’m a fan of Orange Theory Fitness so I figure why not try the drink. I’m very surprised and pleased to say I’m highly satisfied with this drink! It doesn’t give me any negative reactions and it lasts a while; well for me! I replaced coffee in the morning for this and I don’t think I’ll ever have coffee again lol Also without even trying, I’ve dropped two pounds in a week. I really think it’s because it does what it says and because I received more energy, I was getting off my butt and finishing my tasks at home at work hence burning more calories! So far it’s been a few weeks so hopefully I’ll continue loving it!
