If you guys are digging into pre-workouts daily because you need the pep, I'd suggest maybe checking into your sleep schedule. And... you know, eat some food. That isn't to say they don't help a little - I know strong people that use them, and they're great for days everyone has when you're just dragging ass - but if you cats aren't sleeping well enough to put forth effort in the gym, you're not sleeping well enough for your body to repair itself and get stronger.
The best part? Sleep doesn't cost a darn penny. It's free.
