Our <ORIGINAL>. The Drink XTC started with and still is going strong. The intensive green colour, his lemon-lime taste - not too sweet and not too bitter – and the well combined ingredients add up to an Energy Drink that gives you anything you may expect … and more! As his name already indicates, the main ingredient is GUARANA, combined with Taurine and L-Carnitine, a perfect combination! As for all of our products, the production is done under HACCP conditions by using crystal clear water from the Austrian alps. (also available with KOSHER or HALAL certification)
