Are the pre-workout supplements you guys are talking about like C4? The stuff that just gives you better pumps in the gym?
I don't really consider c4 to be a pump PWO although it has some pump ingredients.
For pump I use White Pump, Hemovol and CM2 Nitrates.
I stack that with a stim pre work for increased energy and focus.
The PWO's that we have been mostly talking about are energy and focus PWO's
