    I have used many pre-workouts, when it says watermelon it truly taste like watermelon. No bloated feeling and great pump.

  11. Stephanie Vance

    The first day I used it I got that tingly feeling, but after the second or third time that went away. This pre-work works great, keeps me awake, alert, and focused during my early workouts. The watermelon flavor is good too.

  12. Tayla Brodzky

    Great taste. Provides the energy and focus needed for training, without harmful chemicals like other brands! It’s one of the pre-work outs I continue to purchase!

  13. Charlotte Geddes

    The flavor -watermelon is really good. This will be my 3rd order. It doesn’t leave you jittery.

  14. Charli Trott

    I really nice boost to your workout. It doesn’t make you feel crazy and moody. I feel like I have steady energy with good recovery after. It’s easy to mix and tastes really good.

  15. Lola Hornibrook

    Love this product! Has a good taste, and actually works. I use it in the early mornings and it wakes me up. I was using Energize from Beachbody, and switched over to this because it is a much better price and the only comparable product I’ve found.

  16. Hunter Upfield

    Flavor for ON is great, and I landed on this as being my favorite preworkout.
    It doesn’t make me shake nor does it have any capsaicins that will make your skin itch and burn.

  17. Daniel Shann

    This pre-workout has definitely become my new favorite and soon to be go-to. I love the watermelon flavor.

  18. Nathan Andrew

    This pre-workout has helped me increase my speed and recovery time after long runs.

  19. Brianna Kelsall

    Much better than most preworkouts. Very clean compared to others and you know exactly how much of each component is in each serving. Flavor is perfect.

  20. Darcy Button

    I’ve just recently started drinking pre-workout supplements before my workouts and let me tell you this product is my new HG! A friend recommended it to me and after HOURS (not kidding) of rigorous research on what creatine, beta alanine, etc were I finally found this product and it had all the right stuff in the right proportions! I get steady energy through my workout and don’t have a crash after which I’m all about. I’ve recently started incorporating 4 sets of 12-15 reps and this gets me through the last few for sure!
