Any pre-workout stim, including the brand we produce, has caffeine. There are tons of research behind caffeine and how well it works as an ergogenic aid for training and performance.
If you cant afford a quality pre-workout stim, use a type of caffeine tablet called caffeine anhydrous about an hour before training as well as some cheap arginine (about 5g).
