There is a actual product there, which is better than some of Logan Paul's other ventures.
Probably not a scam, but from reviews it appears the drink isn't too different to other energy drinks - the hype is purely because of the promoters and will probably move on quite quickly. Reviews said it had some of the stuff for an energy / hydration drink but probably not in the right quantities or ratios or something. Frankly all the energy drink market seems a bit of a triumph of marketing over any substance.
Logan Paul has other things to worry about anyway; he managed to potentially defame his software developer and another Youtuber in a video released where he claimed he was defamed and was going to sue (he wasn't and he isn't). Plus, on the same video, he released a snapshot of the developer's expunged criminal record which is potentially a criminal offence....
