Jack3d Advanced Formula By USP Labs, Pre Workout

The formula has changed since I first tried it, but still a powerful stimulant to give you that extra push in the gym. The taste is also fantastic, will buy again. (Posted on 9/16/2018)

This is my wife's go to pre. She takes one scoop and kills it at the gym. When I take it, I DO take TWO scoops, but they are great for me. No crash at all, no jitters and no headaches (Posted on 9/7/2018)

Great taste, easy mix and energy (Posted on 8/28/2018)

Jack3d. Not what it once was. However in an industry where seemingly everything that works is being banned, I keep coming back to this one. On a one to 10 on pump, energy, focus...I'd say it's a legit 7 on all. Not the best, but a solid work horse of a pre. While others will beat jack in 1 or 2 categories this is an excellent all around start to the workout (Posted on 7/24/2018)

I like the effectiveness and duration of my workouts because of this preworkout more than others I've tried. I also appreciate how quick the delivery gets to my house. (Posted on 7/19/2018)

If you use it responsibly and dont have medical issues, this product is the best preworkout there is. I've used it since my Marine days dating back to 2010 or 2011. Just the right amount of spark without getting to worked up. (Posted on 6/8/2018)

The product arrived very fast in my country... nine days...
I will test the product. (Posted on 5/21/2018)

To maintain its potent effects, use little. Use only in training that wants to have an accentuated development, otherwise your body gets used to it and will not have so many effects, thus it will spend more money. (Posted on 5/14/2018)

I love jack3d I've been using it for a long time and i keep coming back. The best was how quick i had it in hand. I usually order from a1supplememts it takes them 3 days to ship it. I actually had it hand in two. I will no longer use a1supplememts. (Posted on 9/17/2017)

best ingredients for great pump, focus and vascularization (Posted on 10/24/2015)

First thing I discovered when I got the bottle was it contained no BetaAlanine. Some people probably like that to avoid the tingling, but BA is one of the best supplements for pushing out extra reps.

In a month and a half I gained about 2 lbs, which is about the path I've been on for about a year. Overall the energy spike was quality,not jittery, there was not a crash, and the taste was very good. What I might keep doing is buying this and blending in BetaAlanine, some amino acids, and additional Argenine sulfate myself. That will save me time and mess versus blending my own stuff, give me better taste, and cost about the same. (Posted on 10/24/2015)

10 min after taking the product your workout is monstrous! focus, blast resistance, recommend. (Posted on 10/24/2015)

This is a good pre-work out if you don't like that "wired" feeling. I personally like that "wired/energized" feeling so at first I was like "ummm this isn't working" BUT just because I wasn't hyper doesn't mean it doesn't work because it does. I sometimes take pre-workout as my caffeine intake for the day but with this particular product it doesn't really work that way. You must go to the gym after taking this because that's when you realize it works. I felt so much stronger while working out with this product. So if you want a pre-workout that helps you gain strength and be productive at the gym without that "wired" feeling then this is the product for you. As far as the taste, I'm not a huge fan of the tropical fruit punch, next time I'll try a different flavor. (Posted on 10/24/2015)
