Really short one, but I wanted to post something. I tried a ragnarok Blue Raz sample, I also have a watermelon caffeine free to try later. The blue raz had a great taste, went into solution easily as well with minimal mixing. It gave pretty nice energy although I think I would have enjoyed a second serving with it more I had good performance in the gym and a good overall workout and better than average stamina with short rest times. I plan to buy a jug in the near future to give it a longer test time
