can they give you the runs and if so is there an alternative?

I've never had a problem with any of those.

yes, a lot of caffeine will give you the runs
start with small dosage

I tried T2 - fat loss aid with gobs of caffeine. I got the runs and gas off of 2 pills daily so I've stopped taking it (and I"m bulking up now).

I might be on the extreme side though because I do get overly jittery and paranoid with too much caffeine (never tried ephedra products).

I have never had a problem with them but i primarly only use them as a pre-workout spike. So i wasnt taking in a whole lot of caffeine, I have heard that when your taking a lot of them you can have some issues but it could also be your diet too...i would take anthrax's advice and start slow.
