ANSI’s Xtreme Shock was previously only available in ready-to-drink form. Recently they have managed to pack it all into a 45 scoop container. The supplement may seem like great value because it comes as a buy one get one free however the ingredients in this are far from impressive. L-Tyrosine, arginine malate, beta alanine, creatine mono, enhanced glutamine, caffeine and aminoglycine. Out of all these caffeine would be the only one to really boost energy and pump. Most of the contents are amino acids, the beta alanine and creatine are not original but may add some power to the zero sugar pre-workout.
