I combine it currently with Kre Alkalyn and the increase in strength is really huge).
It has quasi Guarana extract, schnellkettige Carbs, beta alanine and BCAA's combined in one product - suggesting also the high price
However, if you look at the price and tinned merely elicits 15 servings, it's a totally Plated price for me.
Finally you can last the can like to use it as a kickstarter or used for training days where Just missing the pleasure ...
Therefore unfortunately "only" 4 stars for the not in my opinion justified price!
