All pre-workout supplements are basically the same thing. When it really comes down to it, a pre-workout supplement isn't anything more then a fancy energy drink. It's basically a flavoured caffeine drink. It would be almost the same thing as drinking a cup of coffee before your workout. It's not going to hurt you or anything like that but it's basically just an expensive caffeine supplement.
Caffeine will raise blood pressure slightly but if you keep your dosage sensible, it won't hurt you.
I honestly am not a big stimulant guy and feel they do more harm then good. 99% of sleep issues are due to using stimulants too close to bed time. The half life of caffeine is about 6 hours. If you take a pre-workout supplement around 5PM after work and plan to go to bed around 11PM, the pre-workout will still be in your bloodstream in almost full concentrations.
You honestly don't need a pre-workout. It's a big misconception that you need a pre-workout to lift. The best thing you can do to get a great pump during your workout is to eat a proper pre-workout meal 60-90 minutes before you train. Something high in protein, high in carbs and low-moderate in fat. Something like a bowl of oatmeal with whey protein isolate and some natural almond butter mixed in.
