I have to say, I generally don't bother writing reviews but here goes. Been using this for almost 30 days now. Arrived pretty fast and was overall packaged neatly. For the first few days, you feel like nothing is happening, but after a week or so of the prescribed dosage, you suddenly start to feel it. Your energy levels and concentration levels are increased. Your mood is uplifted and you don't get thoughts that would make you cranky. You're able to do more in a day than you would have normally. The key is to be consistent and not judge based on a few doses along with regular exercise. It helped me a lot, hope it helps others too! Like I said on the title. Works great! But don't expect an overnight miracle!
