The REIGN series, known for its high caffeine content, has launched the new REIGN INFERNO line, which includes fat-burning ingredients. Three flavors were released simultaneously, one of which is REIGN INFERNO TRUE BLU. Honestly, based on the appearance and product name alone, it’s hard to imagine what flavor this could be.

In 2001, while living in the United States, I encountered energy drinks through the dance scene and was deeply impressed. After returning to Japan, I found that energy drinks were considered novelty beverages, so I established a comprehensive website in 2013 to share the true appeal of energy drinks. As an energy drink enthusiast, I began drinking them seriously again, collecting over 8,000 varieties of energy drinks from various countries. I am also active as a critic and expert, receiving media interviews.

Flavor of a Clear Chemical Classic

As soon as the can is opened, a strong chemical scent fills the air. I wondered what TRUE BLU would taste like, and it has a distinctly medicinal flavor. It’s a common taste, and I suspect there won’t be any surprises...

Upon taking a sip, the flavor is a classic chemical taste that isn’t too heavy and doesn’t linger much. It’s similar to Rockstar Original or Japan’s ZONe energy drinks, with a chemical, medicinal aroma that sticks around.

The taste itself is mild in both sweetness and acidity, with a subtle aftertaste that hints at muscat grapes, but the dominant flavor is the medicinal, chemical one. It’s not as intense as Rockstar’s flavor profile, and REIGN INFERNO TRUE BLU seems to be more about enjoying that chemical scent.

This is perfect for those who enjoy such an unhealthy-tasting energy drink. Although it’s sugar-free, you hardly notice any unpleasant aftertaste from artificial sweeteners, so you can enjoy the soft, chemical flavor naturally.

Energy Ingredients of REIGN INFERNO TRUE BLU

REIGN INFERNO TRUE BLU
It contains 300mg of caffeine, BCAAs, and CoQ10, the same as the regular REIGN series.

Additionally, the INFERNO series features unique ingredients like citrulline for pump effects, ginseng, the fat-burning ingredient L-carnitine, green tea extract, and chili peppers. The exact amounts are unclear, but I don’t think there’s a lot of each.

Design of REIGN INFERNO TRUE BLU

The design featuring cracked concrete and a rough surface texture gives it a high-end feel. Compared to the regular REIGN series, the INFERNO series has more atmosphere, and personally, I really like its design.

The functional logo on the back also uses the blue REIGN logo, which enhances the overall sense of unity, and that’s a key feature of the REIGN INFERNO series. The regular REIGN series uses silver here, and compared to that, it feels somewhat cheap or lacking in color. I love this colorful vibe.

Overall, both the design and the ingredients seem to be getting better. Until now, REIGN had a strong resemblance to the bang brand, but with the launch of the REIGN INFERNO series, I feel like they’re slowly becoming a more distinct, fitness-focused energy drink brand.
