this is an odl bump....butttt, I'll ad my 2 cents. I used to loooove super pump 250. The max is crap IMO. Jack3d also seems to be crap. I like the stims, and it doesn't do it for me. So, not it's a double strength coffee, or EC (or both). Sometimes, depending on the time of day, I may also add some kind of carb shake (ie. oats + whey).
