Had a buddy get rushed off the football field in an ambulance after taking an Ultimate Orange/Ripped fuel stack he used to take before games lol. That old school stuff was potent as ****.
I used to pop a gas station ephedrine (5.00 a bottle back in the day), and wash it down with original Ultimate Orange.
I dont like stim's these days, but did find a mellow Pre-WO I'm trying (only 1/2 a scoop) on days when Im dragging ass. (Prekaged).
(Mostly SAT mornings workouts if wife and Party on a Friday night). I tried a few years ago (like Jack3d) and would crash horribly.
Mostly its 2 cups of coffee in the AM though on normal days. (We train at 5 AM).
I used to take pre-workout (C4, Bang, Kraken) but began to really dislike the stimulative effect of them. Lately, a cup of coffee and breakfast before the gym get the job done without all the jitters and body tingles.
