Jack3d Review - 12 Things You Need to Know


Jack3d is not your grandfather’s pre-workout. We dug deep into the side effects, ingredients, clinical research and customer service. We scoured the internet for experiences and found tons. Then, we compressed it all to give you the bottom line.

Jack3d Readers: Click here to find out why we're giving away samples of our product, Boost.

What is Jack3d?

First off, Jack3d is a pre-workout with arginine alpha-ketoglutarate, creatine monohydrate, beta alanine, caffeine, 1,3 dimethylamylamine HCL and schisandra chinensis extract. When taken with exercise it’s supposed to boost energy, pumps and focus. One scoop is a serving, but we’ve found users taking up to three.

Jack3d was available from USP Labs. It looks like the only place you can buy it from is eBay and small supplement companies online. We like that there are so many positive reviews and the ingredients are easy to find, but read on…

The Jack3d supplement is a pre-workout formula that comes in powder, created by USP Labs. USP Labs has claimed that Jack3d is one of the most efficient ways to improve performance at the gym.

The product is supposed to enhance everything related to efficiency, fatigue, muscle performance, resistance and more, when exercising.

Yet, the Jack3d advanced formula comes with ingredients that are potentially dangerous, according to some researchers. But still, Jack3d is a bodybuilding supplement used by millions of people around the world.

How Was Jack3d Created?

There’s no firmdate for when Jack3d was initially released. Some studies and data give the indication that it might have been released into the market in 2008 by USP Labs. The Jack3d Label at that time wasn’t the same, it was Jacked, but as the company started to face copyright problems with other supplements of the same name, they had to change it to Jack3d USPLabs.

After some time, in 2012, the product changed from simply Jack3d to Jack3d Advanced Formula, yet it wasn’t until 2015 after the product was changed both in label and composition that it was named Jack3d again, and it stayed that way.

The big change with Jack3d was after the ingredient dimethylamylamine (DMAA) was removed from the formula. USP Labs, in particular, came under fire for including DMAA in a few of their workout formulations, including OxyElite Pro and the original Jack3d formula.

Here is a synopsis of an FDA warning letter from 2013:

In a public warning late Thursday, the Food and Drug Administration said that the stimulant (DMAA)  did not qualify as a legal dietary supplement ingredient and that it could raise blood pressure, potentially causing heart attacks and other health problems.

Since early 2008, the agency has received reports of 86 health problems, including at least five deaths, in consumers who used DMAA products. Although such reports do not prove that the stimulant directly caused the health problems, agency officials warned people not to consume the ingredient.[1]

Today, we can find Jack3d, the same composition and formula with another label. We can also find Jack3d Micro, a product of the same type but without the ingredient DMAA.

Jack3D Ingredients

The Jack3D supplement supposedly increases metabolism, improves performance, enhances muscle resistance and recovering, and even helps to build muscle faster and more efficiently. This is apparently all possible thanks to the ingredients that compose the product. The blend or mix created on Jack3D has been subject of many scandals and studies, but to give you an idea, here’s what this supplement comes with:

  • Arginine Alpha-Ketoglutarate (AAKG)
    Jack3d advanced formula and the original one come with this ingredient, as one of the most important and the reason it feels like the supplement can give a “pumped performance” for strength, resistance and overall muscle recovery. However, this amino acid has been studied before and it has delivered little to no result in performance, resistance or strength in muscles.[2]
  • Creatine
    Found in most sport supplements in the world, it is said that creatine helps to improve muscle mass exponentially, as one of the most important amino acids. It has been studied many times in the past, and has delivered different types of results, making it a controversial ingredient. One study, for example, says that creatine in fact helps to improve muscle performance, recovery and growth. [2][2]

A second study found that muscle got thicker and more resistant after creatine use. While another study, affirms that the ingredient is totally safe, yet it is not as effective as expected. [2]


  • Caffeine
    Another common ingredient in most sports supplements, caffeine is said to promote weight loss, focus, energy, and gives an excellent enhancement of performance in physical activities. But according to certain studies, the effectiveness of caffeine in supplements is yet to be proved entirely. A study on soccer players with caffeine and arginine supplementation proved that performance, resistance or strength couldn’t be improved. Another study affirms that it can decrease oxidative stress, helping to stimulate hypertrophy in muscles and performance. [2][2]
  • Beta Alanine
    Known for having similar effects to caffeine, beta-alanine boosts energy, improves endurance, increases resistance and helps athletes and bodybuilders to have a longer and more efficient training train. However, beta alanine is an amino acid and helps to create carnosine in the muscle, both helpful in increasing performance and recovery.

And of course, beta alanine has been the subject of many studies when it comes to sports and supplementation. One study affirms that the amino acid helps to improve carnosine accumulation, which is related to better resistance and endurance in sports. [2]

  • Dymethylamylamine-HCI (DMAA)
    A derivation of geranium stems oil, known for improving focus exponentially. DMAA boosts cardio performance, makes exercise a lot easier, and eventually enhances blood flow. [2][2]
    However, this ingredient has been recently banned in many countries due to its side effects and possible life-threatening results. According to the FDA, it can elevate blood pressure and possibly induce heart-related conditions to its users. The FDA eventually published a statement to avoid the distribution and merchandising of any supplement with DMAA in the USA. However, an independent study in 2012, affirmed that the ingredient does not affect heart health in any way. [2]
  • Schizandrol
    The Schisandra Chinensis is a Russian flower whose extract can help to improve “muscle-mind” connection, helping to improve focus and muscle efficiency. It is an ingredient found in many supplements and medicine, related to hormone level regulation and decrease in stress levels. There are no research studies relating this ingredient to dangerous effects or safety use.
  • L-Citrulline
    Another amino acid with a similar effect than arginine. After the Jack3d DMAA had to be taken out of the supplement, USP Labs added citrulline to hopefully make the product work the same way. It is believed to be pretty helpful when it comes to improve performance and resistance to fatigue, according to one study. [2]

So, as you see, USP Labs Jack3d is not entirely healthy. Some of its ingredients have been related to heart problems and other conditions. Even though most Jack3d reviews approve the product as effective, its use can potentially cause health problems. Nowadays, however, Jack3d USPLabs is entirely DMAA free. [2]

How To Take Jack3d?

GNC Jack3d is a supplement that helps athletes and bodybuilders maintain more resistance and improve their performance exponentially.  However, not everyone knows how to take it, and some of them might need to avoid its intake.

Here’s how the product should be taken:

For beginners, it is recommended to take only one scoop or one half-scoop before any physical activity. The same goes for women and smaller individuals. This way they can avoid any type of side effect like dizziness or headaches. Some reviewers confirm that starting with half of a serving is better, and to slowly increase the intake within one or two weeks basd on tolerance.

For those who want to mix Jack3d label with other products, it is recommended to take into consideration the amount of amino acids and other energy-boosting ingredients. However, only one cup is recommended when it is going to be blended with other supplements.

For Jack3d bodybuilding doses, it is said that one to two scoops are enough. Men who want to get extra performance can take up to 2 scoops, but only when the body is already accustomed to the product. For women, the maximum dose should be 1.5 scoops.

The product should always be taken at least 30 minutes before training. Even though some people may have faster metabolisms, it is recommended that to avoid digestion trouble, some users should take it 40 minutes pre-workout.

Does Jack3d Work?

Jack3d, neither the original formula nor the current versions, have been clinically studied. Pre-workout formulas are relatively new in the grand scheme, and there is not a body of research on their shorter or longer-term effects.

However, various reviews and statements from users recommend the product as efficient and beneficial. Yet there are other reviews that have also commented about some side effects and potentially dangerous conditions.

In an article from The Guardian posted four years ago, a man talks about how the product benefitted his training, “The focus was amazing. I had tunnel vision. The motivation was mad. I’d never pushed myself that hard in the gym. I could do anything, and my muscles never felt like they would tear. I didn’t feel any burning; just that I could lift whatever I wanted.”

However, despite the significant effectiveness, after five months of taking the product the man reported that he had some side effects, “After a few months, I was taking three and sometimes four scoops. I was beginning to get worried about the way my heart started racing when I was exercising hard. Then one day, my muscles suddenly failed in the middle of an exercise, and I crashed. I felt totally out of it like I was drugged.”

The man affirmed that the USP Labs Jack3d product gave him heart racing conditions which felt wrong and possibly unhealthy. The man stopped using the product despite the effectiveness and benefits it brought when it came to exercise.

On the other hand, there is a study from August 2017, which doesn’t specifically assess the current Jack3d product but gives an idea of what supplement with arginine, caffeine, beta-alanine and other amino acids can bring to the body. This study confirmed that products of this kind could improve the ergogenic capacities of athletes. [2]

For its ingredients, there’s enough validity to say that they work. When it comes to arginine AAKG, for example, there is a study which approves the use of the amino acid as safe and beneficial, both for performance, resistance and even strength in muscles. [2]

Another study on the effects of beta-alanine, affirms that it can enhance training density, fatigue resistance, and even performance of muscles and strength. This study was made on cyclist with a sprint-interval training, where subjects got an improved activity on their bodies after taking beverages on beta-alanine. [2]

Jack3d Benefits

In short, we can say that Jack3d offers the following benefits:

  • Improved strength, energy, focus, endurance, muscle recovery and intensity during workouts.
  • Fast and easy to digest
  • Surprising tastes, including Fruit Punch, Watermelon, Dragonberry, Pineapple, Pink Lemonade, Blue Raspberry and Mango Margarita.
  • Easy to prepare
  • A sugar and carbohydrates free formula

Despite these benefits, the product was believed to be dangerous because of the DMAA ingredient. Today, the product doesn’t include this compound, and while the product is safer, some long-time reviewers have claimed that the product doesn’t have the “kick” that it once did.

Jack3d Side Effects

When it comes to side effects and conditions related to Jack3d, we can name a few. We don’t trust this product for a number of reasons, and the possible side effects are some of them, especially since the product has been banned in multiple countries, including the UK. [2]

In 2013, for example, there was the case of Claire Squires. She was supposed to be taking the product for a few months in preparation for a marathon. A few days before the marathon, she was found dead from a stroke, which was later found to be induced by DMAA, which the product contained until that year when it was later named Jack3d Micro. [2]

Another case, involving the army and military, found a man who died in Afghanistan after having a hemorrhagic stroke. This case was related to the ingestion of DMAA, which came directly from Jack3d. Since then, the DMAA-containing version of the product was later banned in the USA and other countries.

In addition, there is a study relating this incident, which affirms that the death could have been linked to the product, whether it was by the DMAA ingredient alone or with its blend with the other ingredients like amino acids and caffeine. [2] [2]

Then we also have other studies examining the alarming effects of DMAA and the product itself. One study made on a 22-year old man ingesting Jack3D supplement concluded that it could cause cardiac problems like myocardial infarction. [2]

When it comes to ingredients like Arginine AAKG, there are also other studies which can affirm the product could cause additional adverse effects. In a research from 2009, this component was studied on several patients who were suffering from headaches, vomiting, syncope, and palpitations. The common factor among all of them was arginine AAKG. [2]

Lastly, we have a study which approves the use of another ingredient found in Jack3d. Creatine. One of the main components of the product, creatine is said to increase performance on physical activities with no side effects at all, making it a safe ingredient in the supplement. [3]

Bottom Line: Despite and in accordant with these studies, overall we can’t recommend the product as a safe bet. It is important to note that the product, however, in its actual composition, doesn’t have any DMAA, which was the common factor in most cases involving deaths and other Jack3d side effects. [2]

Jack3d Lawsuits and Scandals

As you’ve read, Jack3d by USP Labs has been linked to many cases including health-threatening side effects and even deaths. This eventually escalated on lawsuits and bans of the product in many countries, including the UK, Australia, and the US.

Michael L. Spaling, a man who died in 2013 as a military under the effects of the product in Afghanistan, was one of the victims. His parents in 2013 filed a lawsuit against USP Labs for the product Jack3d and the addition of the DMAA ingredients as dangerous. [2]

The product was later regulated after many years under investigation. According to many sources, six executives of the USP Labs Company were facing criminal charges due to the addition of Jack3d DMAA in the product, wire fraud, and even money laundering. [2]

The indictment from the FDA against USP Labs levied many charges against the product, prohibiting sale of the product and manufacturing within the US borders. The same happened in the UK and Australia the same year. [2]

Bottom Line: the sheer volume of litigation against USP Labs, especially involving Jack3d, is a major red-flag to us.

Jack3d – Scientifically Approved?

As you already know, Jack3d supplement caused health problems with many users before the DMAA was taken out of its formula. Today, however, the product is sold totally DMAA-free, so it is safer and once again available to be sold in the US and other countries which had previously banned it.

Some research studies involving the product, however, found that the DMAA presence and other ingredients didn’t cause any side effect that could damage or affect health in any way.

In 2011, a study of Jack3d and OxyElite Pro from USP Labs determined that the hemodynamic and hematologic system of many subjects didn’t have any changes after several weeks of use. [2]

Since the Jack3d ingredients were changed and DMAA taken out of the final product, there have not been any studies regarding its safety. This makes us a little hesitant to say it is safe or that it is useful, especially since the Jack3d formula has changed at least three times over the period of 10 years. [2]

Research is extremely important for supplements this potent. The caffeine will boost energy and creatine hydrates the muscle, but it’s the stimulants – particularly dimethylamylamine – that make us reluctant to endorse Jack3d.  There are more than a few reports of severe Jack3d side effects. Some have even made it to the news. At DietSpotlight, science gives us the inside story and with this supplement the information raises red flags.

What Do Users Say About Jack3d

Many Jack3d reviews are talking about the product, that it’s efficient and so on. We could find many Jack3d Amazon reviews, some of them approving the Jack3d ingredients as entirely safe, others inciting other to buy Jack3d, and more.

Today, the product Jack3d Amazon is no longer on the retailer, so we can’t link any reviews to the article. But we could still find some Jack3d reviews, and here are some of the most interesting and useful:

“I’ve had the original, I’ve tried this one and also the Jack3d Mico. Obviously if you did your homework you would know the original is now banned due to DMAA; so goes to say that the original had the BEST energy boosts. This “Advanced” model is still great, with a great dose of energy, bursting pumps and high high HIGH focus you can’t go wrong.”

  • Justin Gomes

“So today this stuff hit me different than usual. I took 2 scoops, not the first time either, 1 does nothing and 1.5 gets me shaking and bowl movements are not good. I’ve used Pre Surge before and C4, which had no bad side effects. I took 2 scoops and went to the gym, excessive bowel movements started as soon as I walked in, shaking and hard heartbeat started to follow. Tunnel vision, more bowel movements, wanting to throw up and excessive sweating and BAD dizziness started.”

  • Ashley G

“Works almost as good as the original kicks in quick works the entire workout and taste is pretty good on top of it well the blue raspberry does I would order it again.”


The Bottom Line – Does Jack3d Work?

Are we searching the internet to find some Jack3d? Well, the caffeine and creatine are good additions, but we are very hesitant about suggesting this one. Dimethylamylamine has been associated with some strong side effects, and there is simply not enough science on effects of the current formula.

In conclusion, we can’t recommend  Jack3d. It is a product with very limited research studies in support of its efficiency or benefits, and it is a supplement which has been subject to previous lawsuits and scandals involving  life-threatening cases. The product has been redesigned many times and has changed its ingredients as well.

If you want to make the most of your workout, why not replace Jack3d with a supplement that’s designed to boost testosterone, increase energy, and work with clinically tested ingredients?

Among the best products we’ve seen this year is one called Pronabolin. This natural testosterone booster is made up of nine scientifically tested ingredients. These are shown to help with energy, muscle growth and more. There are tons of reviews for the supplement and all talk about amazing results.

Plus, the makers of Pronabolin are confident in the formula so they’re offering a 120-day money-back guarantee and a multiple-bottle discount.

Previous Jack3d Review (Updated September 5, 2014):

What You Should Know

It is no big secret that we live in a world of supplement formulas. These days you can find a supplement for most weigh loss or weight gain goals. Well, one product that aims to assist users with incredible workouts and substantial muscle gain is Jack3d. This is a powder formula that is combined with water and blended. Unlike many weight gain products, Jack3d is directed to be consumed before you work out.

A few of the main active ingredients incorporated into this powder supplement are Arginine Alpha-Ketoglutarate, Creatine Monohydrate, Beta Alanine, and Caffeine. While Arginine Alpha-Ketoglutarate boosts the user’s strength and power during workouts, Creatine Monohydrate aids with the building of lean muscle tissue. Beta Alanine is added to this formula in order to heighten endurance, and Caffeine is supposed to combat fatigue and drowsiness. The official Jack3d website provides a complete list of ingredients, as well as price comparisons pertaining to dealers that sell Jack3d powder.

List of Ingredients

A proprietary blend of the following; Arginine Alpha-Ketoglutarate, Creatine Monohydrate, Beta Alanine, Caffeine, 1,3-Dimethylamylamine (Geranium [Stem]), and Schizandrol A. Other ingredients are as follows; Citric Acid, Natural Lemon-Lime Flavor, Acesulfame-K, Sucralose, Vegetable Stearate, Silicon Dioxide, and Chlorophyll (For Coloring).

Product Features

Jack3d works in a similar fashion to many other workout/weight gain supplements that assist with lean muscle building. Basically a serving of this powder is three scoops, which are combined with water and drank 30-45 before the workout. In turn, the user should experience lasting energy, heightened endurance, improved focus, more strength, and muscles that pump significantly during the workout. A few testimonials are presented on the main website, as well as descriptions of the main ingredients. It is also stated that Jack3d is free of sugar, carbs, fat and calories. It sells for around $23-$33 per container, and comes in flavors like fruit punch, grape bubblegum, and lemon lime.


  • Jack3d may heighten energy levels and endurance for working out.
  • This powder formula may increase lean muscle mass.
  • Jack3d is sugar-free, fat-free, and calorie-free.


  • It does not appear that Jack3d assists with weight reduction.
  • Some medical professionals do not recommend the use of Creatine Monohydrate.
  • Side effects may occur in some users.
  • Jack3d contains significant levels of caffeine.
  • There is no money-back guarantee offered with this supplement powder.


Overall, Jack3d comes across as a pretty standard supplement formula for muscle gain. However, this does not appear to be a product for individuals striving to shed excess body fat. While Jack3d does have certain ingredients that have been linked to lean muscle building, it does not aim to burn fat, suppress hunger, or heighten thermo genesis. Therefore this is not a good product for men and women trying to lose weight.

10 Jack3d Reviews

  • Is there anything in it that is banned by UIL.
    Charles Lee

    My son is a Junior in High School and wants to use Jack3d. It is safe for him? Is there anything in it that is banned by UIL. Thanks

    • Dan Bisbee

      I would not recommend a High School age person take this. This is a hardcore supplement and would be better off taking Kre-Alkaline.It can be addictive and has some side effects. I personally love this stuff. I feel like ripping the doors off at the gym by the time I get there. I’m 6’4″ 250lbs and 1.5 scoops works for me. Taking 4 scoops of this stuff could kill you. It is loaded with caffeine. One other ingredient 1,3 Dimethylamylamine was used as a nasal decongestant and is banned in a lot of world sports. It is also used as a recreational drug in higher doses in place of benzylpiperazine. Overall I love this stuff, but do some research before taking it and always follow the recomende dosage.

    • Maribel (Editor)

      Hi Charles! Please make sure to consult with your son’s physician before he starts a new product.

    thank you

    • hellspawn

      Nutrition is about 2/3rds of what you look like. your Work out regimen is the other 1/3rd. eat ALOT your looking at anywhere between 6-8 meals a day. HEALTHY meals, mix it up with you meats veggies starches and NATURAL sugars such as fruits. a great line of products that seems to work well especially for mass gains isn BSN. Lifting is going to give you those extra pounds and that solid look. Do reps between 8-12 with a medium to high weight. remember high reps low weight will burn fat and cut you up, super high weights and extremely low reps is power lifting for strength. mix your work out up every 4-6 weeks so that you dont hit aa platue. this should start you up, research products and work outs. hope this helps

  •  Like the product but use it properly
    curtis h. (Verified User)

    I like jack3d also, the directions say to start w/1 scoop the first 3 times you take it and then you can up the dose to 1.5 but no more than that which is confusing because the very next sentence says that the ideal dose is between 1-3 scoops for workout domination. Start slow and work your way up but I wouldnt exceed 2 scoops as this stuff is potent.

  •  Good for skinny not for big.
    shawn johnson (Verified User)

    jack3d works pretty well for me except that the recommended dose is 2 scoops, and 3 at max i dont feel the effects unless i take 4 scoops and im 5’10 205 pounds. so if you are skinny and trying to gain more muscle i think its great but if you are big, i recommend something else.
