I really love jacked. About 1/2 way through my 3rd tub and still get crazy energy and great warm tingles. Only complaint (and not really much of one) is would love to see more NO type products added to it to increase the pump. I usually use pre-workouts for the energy since I train in the evening after work and nice to have a little boost. I have ordered bulk powder and now add some extra AEE, CM, L-norvaline and some BCAA for good measure. Have have started to get a crazy pump along with the crazy energy. I would love to see Jacob look at adding his "special" NO blend into this product. And add a few high quality NO increasing products. I know this would increases the price but you could easily increase the price a little to cover the cost as long as it stays just as effective. Jacked is or should quickly become the best pre-workout. I had a few people I know try it and everyone loves the energy.
