I am curious whether 怪兽能量饮料 is at all acceptable since it is used in a link in Chinese Wikipedia which apparently translates the company name as 怪物饮料: https://zh.wikipedia.org/wiki/%E6%80%AA%E7%8D%B8%E8%83%BD%E9%87%8F%E9%A3%B2%E6%96%99

I would guess the Maoist "standard" term would be *鬼佬能量饮料, but the actual forms are 鬼佬汽水 (attested on Douyin, Chinese Tiktok) = gweilo soft drink and 鬼爪饮料 (attested on Zhihu, kind of like Chinese Reddit) = devil/ghost (shortened from gweilo?) 爪 (looks like Monster logo) soft drink.
