While yesterday saw Optimum Nutrition introduce their supersize 70 serving AmiN.O. Energy, an exclusive volume produced just for Costco. It turns out the brand have a little more up their sleeves for the same trend setting supplement, with yet another variant. The latest news coming out of Optimum sees a premixed version of the popular caffeinated amino squeezed out into a 16 fl oz bottle (475ml). At the moment we are uncertain as to whether or not the AmiN.O Energy’s formula has been carried over dose for dose, ingredient for ingredient to Optimum’s premixed edition. However we can’t imagine anything more than the usual serving size, especially since if it were up in to the area of two servings it could result in an uncomfortable amount of caffeine. The only other detail we have outside of the product’s name and volume is it’s menu. With so far just the two pictured flavors confirmed in watermelon wave and orange blast, and unfortunately no idea on when the supplement will arrive.
