I've used jack3d and white flood. I prefer jacked. MUCH smaller amount of powder and 1.5-2 scoops just gives me enough extra push on days I'm not feeling it. I sip it while I watch the motivational vids on youtube. If that combo isn't enough to get you going, then you need a couple days off.
I may try something new after this jar of jacked is gone, but not sure yet.
