Its pretty similar to eca except that you feel a little less "gittery". The reason is that NYC uses norephedrine rather than ephedrine. The norephedrine molecule is larger and has a harder time crossing the blood/brain barrier. It isn't less effective, but you feel less wired.
Whats up wolf. This is ruffian from the fitnessboard(if this is the same cjwolf). I've never used NYC before, but I got some ripped fuel from the damn walgreens for 14 bucks and it worked better than anything I have ever taken.
