There have been better tasting energy punches before, but Knockout's attempt is not all bad. Actually, it is quite good despite being a rather stock flavour, with all the strong sour cherry and passion fruit notes expected. There are some mild referrals to pineapple and guava coming in more explicitly towards the end, in addition to brief citations of lime and tangerine. There is nothing new with One Two Punch, but it is a smooth experience that is okay with its own humbleness.
Lasting two plus hours, the kick lasts nothing over two and a half hours. Each can contains: caffeine (160mg), B vitamins, and taurine. Overall, Knockout One Two Punch is a fairly enjoyable budget beverage that plays it all too safe.
