Referred to by the brand as “the world’s best pre-workout”, and known by fans as Supersize. Is Athletic Xtreme’s energizing entry into the competitive pre-workout market, which has been around for quite sometime. Despite it’s lengthy life out and about, the product is only available in the one flavor lemonade. While the single option menu may not be a problem for some people, for those after a bit of variety and trying to stay faithful to Supersize, the one taste can make things a little difficult. As it turns out Athletic Xtreme are due to double the supplement’s list of options in the next two months with a second flavor. The variant is the common blue raspberry, which will be joining the pre-workout’s menu with an unchanged formula. There is no exact for when the taste will arrive, with the estimate of around eight weeks or two months the best we have at the moment.
