most caffeinated drink?

[info401]

looking for the most caffeinated drink, say at dunkin donuts. need something to get me very hyper. is ice coffee a better suggestion vs. black coffee with extra sugar?

The coffee ingredient is the main thing you are looking for. It does not matter if it is black, with ice or cream. If you look at this caffeine chart http://www.volcanicacoffee.com/coffee-articles/caffeine-content.htm
you will see that coffee is one of the highest beverages.

So drink up to get juiced up in any method. The effect will be the same as long as you have the same amount of coffee in your drink.

I believe Toddy has the most caffeine. It is a cold water brewing method.

I believe AM/PM is advertising a extra caffeine coffee (Fill your cup with our new High Voltage Java.™ Then top it off with one of our many flavored creamers and powders. It packs a perk and gets you going." I'm thinking that the "High Voltage" is some sort of artificial introduction of caffeine to the coffee....any others care to guess?
