This is an energy drink. Not that big it is 8.5 fl oz can. Same shape just shorter. Taste a lot like some Red Bull but it is Philippine I believe. Nice green with a bull skull on the front. I always saw it in the store so I figure I give it a try to keep me awake. Energy drinks usually don't do it for me and I can sleep after having caffeine and energy drinks. If you enjoy drinking red bull give this a try, just from somewhere different.
