Its in a 500ml can. I can't remember exactly by how much, but it's around 3x stronger in terms of taurine/caffeine levels than red bull AND it has vodka in it! Unnecessarily strong, made me feel edgy rather than awake, and i'm sure my heart agreed too!
.....a friend of mine was drinking it on the streets, and a Russian passing by stopped and told him not to drink it due to how unhealthy it is. If a Russian is telling you that, it must be true and you better follow their advice
