MDX was basically the original Mountain Dew flavor formula, with things added such as maltodextrin, ginseng, taurine, d-ribose, and guarana added to it to give it the energy drink kick. It also had a higher caffine content than original Mountain Dew, despite having the same basic taste and color as it.
