I don't know if anyone else likes caffeine (and other nootropics), but #GamerSupps has 20% for 24 hours with creator codes.
It tastes good, has #waifu aesthetics (if you're into that), sugar free, mixes without grainy residue, and is fairly cheap. Compare to energy drinks/soda at $0.32 per drink (I use 2 scoops in a 24 oz shaker so it's $0.64 for me).
My only problem is that some of the canisters are ecchi enough that I don't consider them to be safe for work and have to peel the labels off.
