Jack3d is a pre-workout supplement designed to fuel your workouts with energy, focus and great muscle pumps. But does it work?

  • No sugars
  • No calories
  • No maltodextrin, which can spike insulin levels and make your body store fat
  • No magnesium, which at high levels can give you the runs
  • No artificial dyes


It tastes very sweet. Really, you’re drinking such a small amount (4 to 8 ounces) that taste shouldn’t be a factor in your decision. I mean, you wouldn’t order a glass of lemon lime flavored Jack3d at a restaurant, but it’s drinkable. No real complaints here.


The question everyone wants to know, is “does it work?” In a word, yes. One big, full scoop and within 15 minutes I was ready to throw some weights around. It’s not a sugar-high type of energy where you are bouncing off the walls for a few minutes. It’s a controlled high. I was energized and focused, albeit slightly jittery/tingly. Music sounds really good after I take Jack3d and it always elevates my mood.

I feel that Jack3d really comes through with endurance. You will feel energized and focused long after your workout and there is no crash and burn. However, if you work out at night and you plan on going to sleep within the next couple hours, you may want to reconsider.


As for promises of increased muscle pumps, I’m not quite sure I noticed any difference. You don’t have to feel a “pump” in order for your muscles to grow, so this doesn’t really matter to me.

The only downside of Jack3d is that I felt a bit jittery initially, but once I hit the weights that feeling subsided. Don’t take this if you have to focus on writing a paper or reading a book afterwards. Now, I never have caffeine in any form, so if you are used to drinking coffee or energy drinks, you may not experience this.


At $26.99 for a 250 gram tub with 45 (1 scoop) servings, this is a pretty good deal.

On a side note, I noticed a spelling error in the little fold-out that USPlabs sends along with Jack3d, explaining how it’s superior to other pre-workout supplements: “This ican be very unhealthy and toxic…” Really Jack3d? Moral of the story: don’t pay a bodybuilder to edit your print marketing materials 😉

  • […] tend to work differently for different people. For instance, my body responds the best to Jack3d. Fast Twitch has a 7.7 rating on, so obviously some people enjoy […]

  • […] I had high expectations for SuperCharge. Overall, it was a mixed bag. While I felt I had a good amount of strength in the gym and was able to pump out more reps, I just didn’t have the mental focus, energy or endurance that I was expecting–that I normally have when I don’t take a pre-workout supplement. I definitely moved a lot of weight, and that’s a big plus, but I didn’t feel that added energy that I have felt from other pre-workout supplements, like Jack3d. […]
