If you want that much caffeine, buy a 100g on the auction site, and stick half a teaspoonful in a glass of Coke.
Then decide if you like it 24 hours later - when you are wishing you were dead after spending the previous 12 hours jumping around like a bean, with muscle spasms, stupid pains and cramps in your chest and stomach. I can guarentee you will have the worst day of your life and it will will put you off caffeine FOR EVER.
It's not nice, big or clever to take too much of that rubbish - and I'm surprised drinks with that amount of stimulants are not banned, as they are actually starting to kill people.
