This stuff is the best, pre-work out supplement I have ever taken in my life. I haven't taken much, but it has definitely won my heart.
I have taken
NO Xplode--- GARBAGE. Within a month I broke out with hives on my back and had an allergic reaction all of a sudden.
I have taken
Superpump 250- loved it, but it absolutely gets blown out of the water with Jack3d
I have stacked Phenadrine/ w/ Slin Sane and Plasmajet.. Love it and it comes pretty dang close to this but I still would take jack3d because-
It's a hell of a deal..
I took 2 scoops (I weigh 230) as opposed to taking 2 pills of Phenadrine, 2 pills of Slin Sane, and 10 pills of Plasmajet to get close to the same pump I had. That was a great stack, but I'm very sensitive to the phenadrine now. It's weird because my body with pre-work out powders I'm completely fine, but after taking phenadrine for a few days, even one pill, i feel palpitations coming and I absolutely can't stand that. Of course this is just me, and I loved that product too.
But i DEFINITELY recommend this product to everyone looking to get a pre-work out boost. This stuff is insane. I worked out like a champ today, I was super setting everything and felt much much stronger, more powerful, and more vascular.
And I have this sh.it to also thank for keeping me up till now since I can't sleep-- I worked out at 8 like a dip shiiettt.
But anyways great product USP labs. Great great job.
