Formula change, worthless now.

There is no way Monster didn't drastically change their formula. It's been months since I've had an energy drink. One Monster Ultra should have been more than enough to kick me instantly into high gear. Instead, I'm down two and I barely feel a thing. I the ingredients and what do I find? There isn't even ginseng in this anymore! It's ginseng FLAVORED! Who knows what else they removed as finding pictures of old Monster cans is shockingly difficult (I wonder why?). All I know is that the Monster energy blend reads: taurine, l-carnitine, caffeine, inositol. So basically, this is a caffeine pill and a b vitamin, as carnitine does nothing for energy, taurine does nothing at all, and inositol is worse than nothing, it's a sugar alcohol that will give you diarrhea. I would demand a refund, but I seriously doubt I'd get one.

Love the zero sugar!

My husband drinks at least one a day. We buy monsters by the case and the white is one of our favorites. I was really grateful when it first came out that it had zero sugar. That was really important! But even more so, it doesn't taste like other zero sugar drinks out there with the funny aftertaste. It's just good and tasty.

Slimy yellow substances

After about 2 weeks I’m on my 6th monster from this box and when I drink it there’s gross slimy yellow stuff inside. It’s made me sick and I’ve never had this happen before. I want my money back but nobody will contact me. I don’t want the rest of these monsters.

The drink of the Gods

By far the most superior tasting drink I’ve ever encountered. Whether you’re tending to your crops, building ships in Kattegat, or just making it through a grueling work day, this drink gives you the energy you need while still tasting amazing. Thor himself would be proud.
