USP Labs Jack3d Pre-Workout Ingredients Review

USP Labs Jack3d pre-workout is among the most popular pre workout in the world, so it’s not wrong for bros to assume that its formula supports that title. The first thing I noticed is the modest serving size of 5.55 g. Normally, some of the best pre workouts I’ve reviewed have upwards of 8 or 10 g per serving, so I’m now wondering if USP Labs Jack3d pre-workout is all hype and no substance.

Well, let’s check out the USP Labs Jack3d pre-workout ingredients before we make any hasty judgments.

  • Arginine Alpha-Ketoglutarate. It’s a salt of the amino acid arginine and alpha-ketoglutaric acid. It’s mostly added for its nitric oxide and pump benefits. On top of that performance benefit, it’s also been shown to help with insulin sensitivity, liver health, and even up your sex game, bro.
  • Creatine Monohydrate. Every bro who knows their stuff knows what creatine is and what it can do for you. For the nooblets out there, creatine is the de facto number one pre workout ingredient for gym performance and muscle building. It’s not the best in either, but it combines both in a balanced manner. Monohydrate is the best form for creatine, though there could be instances of bloating for some users.
  • Beta-Alanine as CarnoSyn. Beta-alanine is known for its raw strength benefits as well as muscle-repair support. CarnoSyn is the most premium form of this compound and we’re glad USP Labs Jack3d pre-workout invested more on such a good pre workout ingredient.
  • This is the world’s number one drug. Seriously, you couldn’t go a mile without meeting someone who wants to drink coffee at that moment and with good reason. It helps give us a boost of energy as well as even make us burn a bit of fat.
  • 1,3-Dimethylamylamine HCl. Also known as DMAA, it’s a powerful stimulant that makes the user feel like the Hulk. This is actually a banned ingredient and what got the people behind USP Labs Jack3d pre-workout into trouble (more on that later).
  • Schisandra Chinensis. This is actually an adaptogen similar to ashwagandha.

USP Labs Jack3d pre-workout Review: formula analysis

Gotta admit, halfway through my USP Labs Jack3d pre-workout review, I doubted the product due to the really modest dosage of 5.5 g. But upon seeing the short list of ingredients, I realize I judged USP Labs Jack3d pre-workout too early.

AAKG, Creatine, and Beta-Alanine probably dominate much of the serving size, what with these three being USP Labs Jack3d pre-workout’s main ingredients. If I were to hazard a rough guesstimate, I’d say AAKG is at 1.5 g, Creatine at 1.25 g, and Beta Alanine at 1 g. These are all really small dosages individually, but we’re not looking at an individual dosage. We have to consider the synergy and I say there is evidence of it here in USP Labs Jack3d pre-workout.

We’re talking about a combination of pump + recovery + endurance in a 3.5 g dosage, so it’s actually not that bad.

With the rest of the dosage, we have Caffeine, DMAA, and Schisandra. To play the guessing game again, can I bet on caffeine having a whopping 300 mg, DMAA 50 mg, and the remaining 45 mg going to Schisandra? This is why I hate prop blends, bro. Just a headache to work with.

Going with those assumptions, Caffeine is definitely overloaded as we see 250 mg caffeine as the limit for pre workouts. To put this into perspective, 300 mg caffeine is equivalent to drinking three cups of freshly brewed coffee in one go. That is simply INSANE, bro. I love coffee, but I’ve never downed that many in one go. Maybe throughout the day, but not in one serving, no. Some websites estimate caffeine to be at 100 mg, but I’m not buying it unless I see proof from the product itself.

At 50 mg, DMAA is at the higher end of the dosage recommendations. It’s definitely a potent stimulant and fat burner. The recommended starting dosage is at 25-40 mg, but my experience makes me assume USP Labs Jack3d pre-workout put at least 50 mg here for good measure and effects.

The schisandra extract is a decent adaptogen, but I think it needs more than 45 mg to work the way it’s advertised much like rhodiola rosea or ashwagandha.

Why did USP Labs Jack3d pre-workout get into trouble?

A quick google led me to news reports of USP Labs Jack3d pre-workout, specifically its DMAA content, being the reason behind some athletes and even soldiers’ deaths years ago.

The danger was how DMAA had side effects that included narrowing of the blood vessels and arteries and elevated blood pressure. These can then lead to shortness of breath, chest tightening, and a heart attack. Then there’s also the issue of DMAA giving off false positives for drug tests.

Because of those two reasons, the FDA has since banned DMAA as well as any supplement that has this in their ingredients list.

As of this writing, this formula of USP Labs Jack3d pre-workout is currently banned in Australia and in the UK.

As if the banning wasn’t enough, I also found out that six executives with USP Labs faced criminal charges in 2015 over selling DMAA in the US. And just this week, the last executive plead guilty to “a charge related to his role in shipping a supplement whose label falsely described a key ingredient.”

Bro, this is one mess of a company! In fact, they’re so messed up that I just browsed through their official online store and literally found zero products on sale!

Does USP Labs Jack3d pre-workout have a lot of caffeine?

I can only assume, but I have to err on the side of caution and say USP Labs Jack3d pre-workout does have a lot of caffeine and it could be as high as 300 mg!

How long does USP Labs Jack3d pre-workout take to work?

Based on the ingredients I’ve seen, you can expect USP Labs Jack3d pre-workout to work in as fast 10 minutes if only because caffeine is really fast-acting.

Benefits and side effects

USP Labs Jack3d pre-workout is capable of delaying fatigue, giving massive pump, and supporting muscle recovery. Granted they’re all in their minimal efforts, the effects on muscle are still significant.

The original USP Labs Jack3d pre-workout formula is definitely made for those who know what DMAA is and are searching for products that contain it specifically. We’re talking about gym addicts and heavy bodybuilders who regularly use risky supplements for their bodies.

Beta-alanine gets you a mild yet annoying itch, but that’s nothing compared to the 300 mg caffeine content! Get ready for crashing, jitters, and maybe a bad headache. That DMAA dosage won’t sit quietly too, even if it’s in a tame 50 mg dosage.

DMAA could exacerbate the side effects associated with USP Labs Jack3d pre-workout’s caffeine content. What I’m trying to say is, don’t take too much if you know what’s good for you.

USP Labs Jack3d pre-workout Review: pros and cons


  • Familiar ingredients. I didn’t need to look up any of the ingredients added
  • Get ready to wreck the gym, bro!
  • Tons of energy. I actually think you will get too much energy from this.
  • Good price! About $30 a can!


  • Prop blend. I hate guessing.
  • Mild dosing. I kinda want more than just a gram of creatine.
  • Too much caffeine. I don’t recommend taking more than 250 mg in one go.
  • DMAA dangers. Even at small dosages, DMAA is still considered a risky ingredient.
  • Legal shit. Kinda hard to trust a company with executives facing jail time.

Pricing info

  • 1 Can (45 servings): $29.99
  • Available online and in retail stores

USP Labs Jack3d pre-workout Review: summary

Look bro, I’m going to be honest here. USP Labs Jack3d pre-workout is a good pre workout with just some really bad publicity around it. It has all the makings of what a pre workout consists of: Pump, strength, endurance, energy, and even muscle growth support. However, I can’t shake the fact that it’s gotten a lot of legal trouble over the past few years.

If we remove the legal problems USP Labs has encountered, I would strongly recommend this. DMAA can be used safely so long as the dosages are within reasonable ranges like the one we have here. It’s also a good buy at $29.99 a can, so people will be missing out on a really good supplement if they just saw the whole “banned” issue and rode with it.

If you think USP Labs Jack3d pre-workout is dangerous, then it’s okay. I get it, bro. With all the great pre workouts I’ve reviewed, there’s a small chance I’ll take USP Labs Jack3d pre-workout.
