Jack3d, excellent product.
White Flood, also an excellent product.
Try mixing them together, makes a great ****tail that will whip your ass in to the fourth dimension. So that would be 3 scoops or Jack3d and a 2 scoops of White Flood. You body is showered with the strong kick of Jack3d, rapes you with the synenergy of White Flood, and then you experience a unique flush of White Flood's skin warming stimulation. Resulting in quite a nice experience of energy and focus. The training equipment literally wheep at your presence. The treadmill becomes a tsunami of sweat, the bench presses split in two, and the leg presses...Oh....the leg presses... You invade Jacob's, from USPlabs and Kane's, from Controlled Labs, nightmares. Resulting in them requiring therapy for the next 38 weeks; yes, the average duration of a human pregnancy.
Yep, it's quite awesome.
But, on a lighter note, I found BSN's Andorush to deliver quite a good preworkout stimulation as well. Just don't expect any nightmare spotting.
