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.

A drink that lets me think

Monster drinks are wonderful. They keep me alert and active. I had a stroke and lost some memory. They have really helped me focus and being useful around the house. I appreciate them.

Taste Buds Zapped, Productivity Maxed

If coffee is the polite handshake that starts your day, then Monster Energy is a double fist-bump followed by a chest bump that says, “LET’S GO WIN THIS THING.” I can’t say it’s given me actual superpowers, but after cracking open that white can, I suddenly find myself reorganizing closets, power washing the driveway, and contemplating a casual 5K — all before breakfast. The flavor? Imagine citrus and lightning had a love child. It’s surprisingly tasty for something that feels like it could also fuel a dragster. On the downside, Monster does have me questioning whether I’ve developed the ability to hear electricity. But hey, what’s life without a little buzz (literally)? If you’re looking for a drink that says, “You’re not tired, you’re just under-caffeinated!” then Monster’s your wingman. Just maybe don’t text your ex or adopt three puppies right after. 5 stars for the energy. Zero stars for my ability to sit still. Would absolutely recommend.

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.

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.

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.

Outrageous Price Increase….

What is outrageous, a complete Monster is to speak is the cost of a 12 pack of this went up in price overnight! By $4.00, I love the flavor of this beverage, but can no longer afford to drink one every now and then. But a 25% price increase overnight, feels greed to me. This like a lot if other things will no longer be affordable by the working people.
