Amazing enhanced flavours, love all the x50 range . This by far is a go to . Keeps me going/ wired throughout the day while fasting. Great results, have my daily take of 1 serving a day in my 1 litre bottle . Highly recommend this for coffee/ energy drink replacements . Also note to have water throughout the day , to help flush out the caffeine intake . You may struggle to settle and sleep properly if not . Follow as directed with advise on the packaging.
