CAFFEINE CONTENT: 250 MILLIGRAMS PER 12 OUNCE CAN.
RATING: 8.4 OUT OF 10.
I find it shameful that my city received shipments of this drink months after the first review of this drink was written. Well I guess that doesn't matter now because I have obtained the most powerful Rockstar ever made. They called it Rockstar 2X Energy and it's basically a 12 ounce can of Rockstar with a mind-boggling amount of caffeine. The flavor is not really the greatest, if I'm honest. The original Rockstar had a candy flavor to it, extremely similar to Smarties. This extra strength version is the same flavor, only with a caffeine bitterness. It's decent to say the best, but this is not a drink I recommend for the taste. The energy blend typical Rockstar and it is as follows: 200 percent daily value of vitamin b2, 100 percent daily value of vitamin b3, 100 percent daily value of vitamin b5, 100 percent daily value of vitamin b6, 100 percent daily value of vitamin b12, 1,000 milligrams of taurine, 250 milligrams of caffeine, 100 milligrams of panax ginseng, 100 milligrams of l-arginine, 25 milligrams of l-carnitine, 25 milligrams of inositol, and 25 milligrams of guarana seed extract. Well obviously the caffeine content is just incredible. It actually has 20.8 milligrams of caffeine per ounce, making it twice as concentrated as a regular Rockstar. I was expecting the kick to be mind-blowing, but then I remembered I had a high caffeine tolerance. You bet it woke me up, I only slept for about 5 hours last night so I needed the boost. The crash came about 5 to 6 hours later. Everything considered, Rockstar's latest creation delivers a worthwhile kick, but it also delivers a so-so flavor. 8.4 out of 10.
