Do energy drinks/shots really work?
ALL of these contain CAFFEINE. So you need to assess whether or not you operate well with that substance in your blood stream. People with high blood pressure or natural anxiety issues, should take them with care. 5 Hour Energy Drink DOES contain caffeine. Never take anything without reading the label yourself. And, watch for the ingredient: Pseudoephedrine. This is the ingredient used most often in diet substances. It is also one of the base ingredients in making Chystal Meth; again, a powerful stimulant. 5 Hour Energy Drink: 5-Hour Energy shots contain B-vitamins, amino acids, some nutrients and as much caffeine as a cup of the leading premium coffee.
