    Pre Workout Like No Other November 13, 2017

    Been using USP Labs Jack3d for a couple of months now. Blows all other pre workouts away! The intensity you feel is off the charts and you can’t beat the price! Definitely recommend.

    Solid economy pre-workout. February 7, 2016

    We could sit here and discuss Jack3D formulas all day and get no where so here's the down and dirty: if you want a good pre-workout foundation without sticker price shock value go with Jack3D. It's a bit more tame than some other pre work outs on the market now a days but still packs a nice energy kick and allows for some good focus. Taste is alright, it doesn't leave me wishing I had a chaser but it's not fruit punch either. You'll feel the get ready to lift feeling shorty after ingesting though the feeling tends to fade rather quickly once I'm lifting. Overall this is a great economic way to get your pre-workout.

    AMAZING! November 24, 2015

    Love the Flavor and the boost I get !!

  • Kristin
    Mixed results September 22, 2015

    Have only used a few times so far. May save for leg/back day when my lifts are more intense as this stuff is powerful! A full scoop isn't even required to achieve a great pump. Overall, great value for the amount paid!

  • Steven
    GREAT! May 27, 2015

    Personally one of my favorite pre workouts out there. Nothing that I have taken comes close. Great pump and focus.

  • Nava
    Bang for the buck! November 5, 2014

    Great product however I have to bounce back & forth between another pre-workout in order to get the same effect. I do always find myself coming back to Jack though.

  • Jonathan
    great October 8, 2014

    loved it

  • Keith
    Great product August 26, 2014

    This is by far my favorite preworkout. No jitters, great taste, and works well on an empty stomach. I prefer this over the micro version.

  • Michael
    Great taste, sub par pre workout May 8, 2014

    I used to always use the original jack3d when it first came out. Since the release of jack3d micro and this new formula for jack3d the product has gone downhill. I just feel hungover when on the product and super spaced out as if it's clouding my focus. I've switched from jack3d to c4 and couldn't be happier since the switch.

  • cesar
    best pre workout May 6, 2014

    been using this for years. It mixes easy and you dont need massive scoops. It takes about thirty minutes and off you go. It is part of my 4 am routine and has been for a few years.

  • TRU
    jack3d March 26, 2014

    This is the best pre-workout product I've tried, the immediate focus is outstanding and I'm able to maintain great stamina throughout the workout.

  • David
    jack3d March 24, 2014

    it doesn't taste as good as other pre-workouts but better than the other formulas of jack3d. the results are intense!!! this is a good pre-workout for mornings. it will keep you going all day with no crash. it does give you gas at times and kills your appetite so eating is a little more difficult. the price is great as well as the value.

  • Ryan
    Holy crap March 22, 2014

    USP Labs have packed so much friggin energy into one scoop, it's insane how many more reps I can throw down in the gym. I've been using it for about two weeks now and I have yet to feel the "crash" that other pre-workouts make you feel.
