Besides this tingling said happened to me is not really much, the taste is okay but taking proved by the poor mixing with the water nasty as something as a last resort remained a residual powder matter how much I stirred or shaking, no comparison with best Body Nutrition Muscle Shock 2in1, Tropical, 20 drinking bottle of 20 ml, which at me a much better pumping brought as this one, the little bottles were much easier to carry, easy pure shake into his pocket and Rinn so that pre Noxx had I mix at home and when man still wants to do what before everything can be delayed a little, so maybe the surge was often not there ... but I would not order this product again ...
