REVIEW: Reign Inferno Thermogenic Fuel by Monster Energy

Reign Inferno Thermogenic Fuel

Feb 2021 Update: Watermelon Warlord review was added.

What is Reign Inferno Thermogenic Fuel?

The new Reign line of energy drinks has a brand extension that promises an even more Xtreme performance boost than its standard offering. Fortified with Branch-Chained Amino Acids, Citrulline, and 300 milligrams of caffeine, Reign Inferno Thermogenic Fuel makes some big promises, like burning calories and accelerating metabolism. After tasting all three flavors (Red Dragon, True Blu, and Jalapeno Strawberry), I fully expect my mortal frame to combust spontaneously, unable to contain the energies contained therein.

How is it?

Watermelon Warlord

Watermelon Warlord is the newest flavor in Monster Beverage’s line of Reign Inferno thermogenic energy drinks. With a name like that, I’m expecting my tastebuds to be ravaged with watermelon flavor. Maybe that’s not great? Artificial watermelon flavor is something that can be tasty in small amounts, but tastes nothing like actual watermelon so can be detrimental if overdone.

As I take a sip of the clear liquid, simple sweetness is the dominant flavor. It is a bit cloying, but the subtle watermelon flavor provides enough interest to cut through the sucralose. Watermelon Warlord seems a bit aggressive of a name for the amount of watermelon flavor here, but Watermelon Democratically-elected Town Alderperson doesn’t have the same impact, you know?

Red Dragon

I didn’t expect their colors to be clear. Reign has seemingly decided to target the consumer who desires to unleash the beast within via scientifically formulated supplementation, but is also very concerned about artificial colors. The flavor tastes of generic red fruit. Strawberry? Cherry? Fruit Punch? Who knows? It tastes red.

True Blu

I went into this thinking True Blu would be a blue raspberry flavored, but instead, it tastes like a classic energy drink, very similar to Red Bull. The citric acid adds a puckering tang that always reminds me of Sour Patch Kids gummies. This one will please those who are looking that the classic energy drink kick, but it doesn’t offer something unique.

Jalapeno Strawberry

My midwestern taste buds were suspicious of this one going in. Spicy strawberries? What’s next, chili-infused chocolate? Oh wait, that exists. The scent is unexpectedly pungent, and actually caused some nasal irritation, like when you smell horseradish. Conversely, the flavor is quite smooth and pleasant. The sweet berry flavor plays very well with the jalapeno. There’s a very slight spiciness at the end that doesn’t linger.

Is there anything else you need to know?

The True Blu’s flavor transported me back to middle school in the ’90s, when I first tasted Red Bull. It was perhaps the boldest thing I’d ever done in my life to that point (maybe still?).

You have to understand that the ’90s were a different time. The Simpsons was the most audacious, boundary-pushing thing on TV. There wasn’t the internet as we know it, only vague rumors of a kid the next town over who took a sip of Red Bull and then his heart exploded on the spot. I survived the 80 milligrams of caffeine found in an 8-ounce can of Red Bull. In comparison, Reign Inferno contains 300 milligrams per serving, which is only a portion of my daily caffeine intake. We’ve come a long way, baby.

Conclusion:

Other than their high caffeine content, Red Dragon and True Blu don’t offer anything new. Their flavors will be familiar to energy drink aficionados. Jalapeno Strawberry was a surprise and provided a pleasant flavor combination.
