So I heard about the NEXT BIG THING in brain performance enhancing pills. Evo is what it is called. I have taken Adderall for a while through high school and beyond to help with ADHD. I don't like the withdrawal effects that come when you aren't taking it though. So Evo sounded perfect since I literally found no negative reviews on it. I ordered some, and messaged the company, leaving my e-mail and phone number because I had questions. Well they didn't respond, so I gave them the benefit of the doubt, thinking they had a lot of customers ordering these "super pills". I got them over a week ago, and have taken one every day. I see absolutely no difference in anything. I have no increased energy, no super improved memory, no increased focus, NOTHING. I'm not just being a pessimist either. I have experienced with a lot in my life, not that I'm proud of it. That being said, I know what to look for. I feel more energy from a protein shake than I feel from the Evo pill, and that is no joke! I have waited 2 weeks for a response, and still waiting. I call them every day, no one is ever there. So much for that "money back guarantee." Please, save your money, and spread the word. You can't post to their site with negative feedback.
