700 mg of caffeine certainly wouldn't have killed someone your size, you were completely fine.

Enough for a scare though.

You'd probably have to down a couple of grams if you're going for the KO.

Still, I've taken ~600 mg at once so I know the feeling, my heart wasn't racing as badly as yours but my hands were very shaky that's for sure.


As for pre-workouts themselves, I used one once in my life. Waste of money IMO, if you lift without them you just get used to it.
