I've been taking Pre-workouts for years and with every cycle I've ran, including sustanon. I've never passed out or felt shitty.

Make sure you don't take the pre-workout on an empty stomach and avoid really stranious cardio. I do 10 mins of pre workout cardio and 10 mins after workout.

Yes, just watch BP levels, and watch for extreme intensity! I almost passed out once because I working at such a hard intensity heart rate shot to 170-185 for extended periods of time and I got dizzy and sat down and almost passed out

If u are not having any BP issues then u should be fine
