Compared to creatine pills that you have to take so many of per day and the powder form without any taste, this was the best and most tasty way of managing the daily creatine intake. Of course it requires water (or another liquid), a container to mix and drink from, and maybe a tool to mix with, but those are not very hard to come by, and in exchange you get this delicious method. Of course, taste preferences change from person to person, but I think pineapple is a commonly appreciated flavor, and I liked it a lot. I used cold water and a mini electric milk frother for mixing, and everything worked perfectly. And yes, it comes with an NPN number. I strongly recommend.
