USP Labs Jack3d Reviews
USP Labs Jack3d Reviews
One of the most controversial and popular pre-workout supplements right now is Jack3d. This popularity comes from a focus on this product’s success as a supplement, but also over the question of whether or not it is safe. You’ll find many Jack3d reviews promising you this is a safe supplement, but other are beginning to question its safety more and more.
Jack3d is designed to promote muscle strength, energy, power, and growth. Using proven ingredients, it should help you increase the quality of your workout and the speed with which you get results.
Ingredients in Jack3d
Jack3d has a simple formula of five active ingredients: creatine monohydrate, caffeine, arginine, beta alanine, and 1,3-dimethylamylamine.
If you’ve been around bodybuilders enough, you know what creatine is. This all-natural ingredient is essential to muscle growth. It stimulates the synthesis of energy in your muscles allowing you to get bigger pumps, faster growth, and more stamina.
Caffeine gives you energy, and sometimes, better focus. It also has the ability to burn excess fat off your muscles and improve your muscle definition.
Arginine is another popular ingredient in the bodybuilding industry. It creates more nitric oxide in your blood and improves blood circulation. The result is the increased flow of nutrient-rich blood to your muscles. This gives your muscles fuel for growth and recovery.
Beta Alanine enhances muscle endurance better than almost any other ingredient.
1,3-dimethylamylamine is the controversial ingredient in Jack3d. The purpose of this ingredient is to give you better focus.
Recent News for Jack3d
On April 30, 2012 the FDA ordered pre-workout supplement companies to stop selling products that use 1,3-dimethylamylamine, due to the potential of fatal side effects. They also announced that the ingredient is synthetic in nature, not natural.
Due to the ban on 1,3-dimethylamylamine , Jack3d and other pre-workout supplements that use the ingredient are not currently available for sale. We expect to see Jack3d back on the market after its formula has been modified to exclude the controversial ingredient.
Does Jack3d Work?
Minus 1,3-dimethylamylamine, Jack3d has good ingredients. Most of them have been clinically proven to stimulate muscle growth and improve workout performance. The pre-workout supplement uses these 5 ingredients in a proprietary blend that totals 4145 mg. We don’t know what the individual amounts are, but the total dose is very powerful.
Before the FDA decided that 1,3-dimethylamylamine was harmful and before Jack3d was taken off the market, we considered it to be an effective product. When it returns to the market, hopefully safer this time, we do think it a product worth trying.
Since Jack3d is not available, we recommend that you try a top-rated pre-workout supplement instead. These products have earned distinction for being effective, affordable, and safe.

I am a 51 yr old female. Tried 1/2 scoop (in 25 ounces of water) and really felt an increase in energy. Hadn't been to the gym in 1 month and the day I went back I tried the Jack and flew through my 1 hour cardio like it was nothing and then hit the weights. I usually get a bit of anxiety before I hit the gym but with the Jack I became 'very calm' and was able to have a very noticeably higher and cleaner oxygen flow. No side effects. I don't drink coffee cuz I can't tolerate caffeine at all and this prodcut had no adverse affects -as I have tried other like products in the past and had felt heart pulpatitions and racing ...but not with the Jack. Love the fruit taste!

44 year old male working out since 19, Just started taking JACK 3 D last week. 30 minutes before workout with some amino acids and the product does what is says. I felt pretty normal going in - I should mention I drink a fair amount of Caffeine and have a tolerance, I'm sure - so 1 scoop will probably increase to 1.5 or 2 very soon. Good focus, good strength, no serious side effects. I was a little worried before first dose but all for nothing. However, I would be cautious taking this if you are not a coffee drinker or used to caffeine/stimulants. Try a half dose if that is the case. Tingly skin from Beta Alanine, I suppose. Not nearly as bad as when I take GASPARI ANAVITE. Use common sense and drink lots of water. If you feel "tweaked" move on to something else. Many people have said this and it's true - a large cup of coffee before working out does the trick as well.

In Germany this product ist called a "powerfull weapon", but it`s only a new hype about a new product. As first I have to say, that Jack3d works, the combination of ingredients ist good. I use always 2 scoops. In the end result ist not false to buy it, but a big cup of coffee ist much cheaper and works similar.

Last week, i spent about 37 dollars on the grape bubblegum flavored jack3d. I gotta say, this is the best ive tried so far, and the price is great. The grape bubblegum flavor isnt the best taste out there, but the pumps and focus i had the past week (4 doses) were VEEERY effective and my workouts were much more intense. I tried HEMO RAGE BLACK before Jack3d, and it gave me bad jitters and wanna run through a brick wall. DEFINITELY RECCOMEND JACK3D !!

I gotta say that Jack3d is the best pre-workout supp I have tried. I given Superpump 250/Black Powder & Hemo Rage a go. I thought they were good but this stuff rocks. I tried NO Explode but it made me sad. Anyway, I was taking three scoops for about 6 months and started to feel the effects diminishing, I was talking to this guy in the gym about it and he said he experienced the same thing after a few weeks until he tried something different (and I know this sounds bad). You cut the top off an eye-drop bottle and put in 1/3 scoop, fill it with water to disolve it then freeze it. Repeat twice more to make a full scoop. About 1hr before your workout: shelve it (stick it in your bum!). I know, I know, you're scrunching up your face or laughing but I am DEAD SERIOUS! It will just blow you away. It doesn't go up a level, it goes up ten! You will not believe how much more you can lift, and for how long. All my major 1MR's went up bu at least 10%. This is a legitimate way to take medicines, I'll let you be the judge..... Just don't do it in the change room.

i tried this for my first time today, i took 1 scoop with about 8 ounces of water. i didnt feel much at all. although i noticed that i am pretty caffine tollerent for some reason, and if i drink coffee or energy drinks nothing happens to me also, so this could be it. i will try 2 scoops tommorow, hopefully it will do the trick.

I am 30 years old and started working out when I was 14 years old for Football. I have always been a bigger dude, and getting pumped as a young guy is easy. The last few years have been a little tougher for me, in just having the energy and pump to get past the plateaus. I am 6'1" tall and I currently weigh 225 lbs. I started taking Jack3d about one month ago, and wow, it works pretty damn well. I get a tingly feeling about 10 minutes after taking it. But more than that, my mindset is just focused. I have a strong desire to lift and go heavy about 30 minutes after the dose. I have tried anywhere from 1.5 scoops to 2 scoops. I settled on the 1.5 scoops because I seem to get the same results. I thnk everyone is different and will experience different results, but I definately feel it, and I feel it has brought back those pumps that I used to get when I played high school and college football. I have lost about 8 pounds of fat, and gained some real good shredded muscle in the last month or so. I think you need to just try it for yourself, and make your own judgement. Adjust the dose in the first couple of weeks to find your proper dose, and then just stick with it and see what happens after the first month. This is by far one of the better supplements to come out.

I only rate this a 3 because I took 1 scoop of the fruit punch flavor as of the first day of week 3 of my workout program I am doing. I am a healthy person, (no smoking, alcohol, drugs) and 175 lbs. I did feel the energy, kind of like drinking a couple cups of coffee or a 5 hour energy before working out. Come Thursday (last day of week 3 for me)I am studying to be a music teacher, and prior to me taking Jack3d that day I was performing vocaleses, so I was okay then. I went to go work out and I ran 1 mile on the treadmill and started biking with a level 5, real relaxed to cool down a bit. My throat started getting this unfamiliar tingling feeling. Then I found that it occured everytime I tried to take a deep breath, and before I knew it I was starting to gag under my own breath. So I went to the bathroom and vomitted 5 times, and decided to go to the nurses station. She noticed my throat was raw (probably due to throwing up) but didn't have the tools to inspect further down, so I was sent to go to the hospital. Hospital ran EKG on me, came back normal. Did blood test, came back normal. Did xray on my chest, lungs and throat, came back normal. In the urine sample, I tested positive for inphetamines. I said what? So the doctor told me to lay off caffeine and chocolate for a while, and in a few weeks I should just stick to the "old-fashioned way" and have a cup of coffee before working out. So, I can't vouch for everyone else, I'm sure there have been positive results, but it just shows that I should just stick alternatives then blends I don't fully understand. So I definitely encourage people to do what the warning says and consult a physician before taking this stuff. And it's true to the person above, there are ingredients in this that do cause you do become more angry. So if your taking any meds for anti-depression or anything, be very wary of mixing this stuff with it!

Best Product I've Used!!!
5.0 of 5.0
21 Feb 2011 - Hanzman
Jack3d from USPlabs is, hands down, the best product I've ever used! I've been taking it for about 4 months now, I lift 4 times a week (Arms Monday/Thursday, Legs Tuesday/Friday) and take this product every time I lift. It takes a minimal amount of time for it to kick in (about 10 minutes as opposed to N.O. Shotgun which took about 30 to 45 minutes). The pumps I get from Jack3d are really good and the tingling buzz feeling is very prominent. It's definitely helped increase my weights and vascularity. I've got several friends also taking the product and they've said the same things "amazing pumps", "intense workouts" and "More Energy". As far as side effects I didnt notice any until about the 4th month I took it, and they were nothing to serious (as far as I'm concerned). Some side effects I've experienced are some slight shoulder acne (not much more than normal though cause I'm an athlete) slightly increased aggression, and some moderate mood swings every once in a while. I've also gotten headaches a few times but that was most likely unrelated. Overall I give this product major props! USPLabs did one hell of a job making an effective product at a low ticket price! Would strongly recommend this product!

Like some of the comments on this board it all depends one the persons health. Everybody reacts differently from supplements. I personnally will not take jacked 3d. Some of the side effects I experienced along with other guys that have taken it have stated that they have the energy but can not have an ERECTION at the time it is being used. I wonder what the side effects will be for long term. I spoke to a GNC rep and she smiled when I explained to her what was going on she simply stated I understand my boyfriend takes it to and immediately reffered me to a different pre-workout. I havent heard anything from any one in person other than websites that it is good. Yes, it does give u energy for more reps and u dont get that drain at the end of the dayalong with tingling of your face after 10 minutes, But I would rather be fit and have a good sex life then being impotent.

I'm 58 and have been lifting weights for 25 years. I have an office job, so working out is extra important. As I got older, staying focused and the amount of weights seemed to diminish. I had never used any supplements before or after my workouts. Last year I started looking on the web for reviews, and settled on Jack3d. I hit the gym 2 to 3 times a week and usually start at 6:00 pm. For me using it each time was too much, sexual performance seemed to be affected. I now use it only on Tuesdays,it seems to wash out of my system in a few days and that way Saturday night with the wife goes off without a hitch. I supplement my other times with 5 hour energy drink. I am totally amazed at how well Jack3d works. I now always get thru all my sets and I'm usually adding more weight or more reps. I take about 1 and 3/4 scoops. Slight tingling and slight stomach upset is all for me, which may or may not be related to the product.Experimenting with what works for you seems to be the key. I hope I'm still lifting at 90.

I have recently started taking weight lifting seriously in an attempt to redefine by body for a more muscular, firm look, i currently am a hardgainer, body type ectomorph, i weigh 205 lbs @ 6'3, when i take this stuff i started with one scoop and eventually worked toward 3, the tingling and tightness in my face lets me know its working, ive felt this before from NOXplode, but it stopped after a week, im about to order my 2nd tub, this stuff works, i feel immense drive, focus and energy to lift more, so much more that i pulled a muscle recently after accomplishing the set. USP Labs is #1 in my book for Pre-Workout Supps, btw do not use Universal its garbage and nothing but fillers.

For the past 2 months, my workouts have been so-so. I find myself not very motivated and usually pooping out halfway through my workout. I went to GNC in search of some supplements. I heard that L-Arginine would be good. The salesperson suggested Jack3d. I was skeptical, but it was $10 off. So, I bought it. I used it for the first time last night. I took 1 scoop with about 1/2 cup of water at 5:45 p.m. By the time I got to the gym around 6:30 p.m., I was pretty "tweaked." If any of you old timers remember the ORIGINAL Hydroxycut with ephedra, the "amped" feeling was pretty much the same. However, I didn't just have more energy, but I was able to lift more. For the first time in 2 months, I completed a FULL workout schedule and didn't poop out and even added 5-10lbs to my routine because the weight I had been using for the past couple of weeks seemed just a bit too light. I'm gonna give this stuff a try and report out on how it's going. Hopefully this will last and get me through a "plateau" and not just "beginner's luck" with a new gimmick.

I have taken jack3d For about three months now with a two week break from it. I started at 205 and now i am @ 183. I started of taking 2 scoops. The energy and the focused I had afterwards was crazy. I'm sure a lot of has to do with your mind making you feel this way. But even then this stuff really makes u want to Get big in the gym. Cant just take the product and expect immediate results. It takes working out at least 3-5 days a week and proper eating habbits. When you start feeling the Tingling feeling in your face then u know it is taking affect. Product may not be for everyone, but does not hurt to try. Overall great product! I am going to up my dosage to Three scoops. Good luck to all those trying to attain their goals. Its hard! Stay focused!!

Ive been using this stuff for about 3 weeks. Ive been looking for a supplement for the longest time that would give me energy, strength, and focus. This stuff is amazing. After 3 years of trying out a bunch of different supplements; i can honestly say this is a the best one out there. The best part about it is that it is not that expensive. you could probably get about 2 months out of a jar; and its only like 26 dollars. Just remember that jack3d is only a pre workout supplement. So buy some 100% whey or something to drink afterwards. All together youll spend about 40-50 dollars. But to me thats better than spending 50-60 dollars for some supplement that the GNC guy is trying to sell you that wont even work. It really is the best stuff out there. I love it.

ive been takin jack3d for the past 6 months an to me its the best preworkout supplement that ive tried. ive worked up to 3 scoops 30 mins or so before i workout. it keeps me really pumped an energetic all the way through my entire workout. when i first started takin it i weighed 122 pounds an my bench max was 165. within a month i was pumping 195. right now im about 6 months into it an im a solid 135 pounds which for me is really good. my bench max has hit 240 pounds. my next goal is to hit 270 so i can be pushin over double my bodyweight. i really recommend using jack3d. if youve tried it an the burning sensation is a little too intense try takin some usplabs Powerfull along with ur jacked. it will make you even more pumped an completely take away the burning sensation but keep you goin strong and energetic

Usp labs' jack3d has given me a better insight into pre-workout pump suPpliments, after using supper pump 250, ganic-f, usn's anabolic nitro hardcore and NO X plode this suppliment gives u confidence in that it doesn't have all those unnecessary fillers and magnesium , I'm only 17 years old and I can tell u this supplement is not for everybody , reading through comment about long lasting un comforts and constant migraines clearly this supplement is not for you don't rant and rave about these side effects the damn thing comes with a warning clearly printed on the front obviosly your either not taking it right by over dossing the amounts taken or by not chcking what ur body can take and handle , I can recommend this supplement to friends but my recommendation comes with a warning, please check with your doc what your body can handle, I will admit taking this supplement within 2 hours of eating or taking a whey supplement will effect the way this supplement effect you, and it doesn't deliver that super energy and extream pumps as the other supplements but it does give that longer lasting effect.

I've been lifting serious for the past 5 years now. I'm 35 and have always worked out, but only recently has it been to make drastic changes in my muscular size and strength. I tried Jacked on the recommendation of my current workout partner. I had been using Nano-Vapor (2nd best I've used) and was reluctant to change since Vapor was doing the job well. I have consistently used 2 scoops 5-10 minutes before I hit the weights. I do a warm-up set after some static and ballistic stretching. The second I hit the heavy set, BAM! The arginine kicks in and my face gets itchy as hell and I focus on the task at hand. I have used various NO products the past 5 years and I am no stranger to the burning/tingling sensation. It happens. It's a natural side effect of the arginine in the veins. I personally welcome it since it lets me know it's time to hit it hard! I'm on my 2nd tub and not looking back. I love that it's a small scoop, so it's no big drinks and no thick drinks either. It's a simple 8-ounces of water with my 2 scoops and I'm out the locker room and into the zone. I totally recommend it for serious lifters with supplement experience. If your new to "the game" it can be intimidating due to new sensations.

The problem with most pre-workout supps is that people think that they are going to be able to do twice as much or more during their workout. You must have realistic goals even with workout supps. That being said, for the sale price you find jack3d at stores now it is well worth the buy. For those who find discomfort ( burning, itching, etc ) you must note your caffeine intake on the days you take it as well as anything containing niacin and other blood rushing ingredients. This will give you the simple boost you need. It will not make you He-Man. I think this product works just fine and is worth the 30+ bucks i spent. (this is my third tub now) You may also want to note the dosage. If you are sensitive to the ingredients ; make sure you are taking the one scoop a day dose or less. Good luck on your healthy journey!

I wanted to try this product for a long time having read that it was the best selling product and having heard from couple of (much younger) friends that it was a great product. Im 35y, 190pounds, 6.2 experiened athletes, work out 4-5 times a week over last 10 years. I took one scoop 30 min before work out, sipping rather quickly while i was driving on my way to the gym. Within 10 min (possibly 5min) i felt the skin on my face was on fire. Some people mentionned about tingling, for me it was more as if i had rub a fresh green chili all over my face (and who would do that!?) Also felt that way on my tighs and arms (although not so intense) I didn't feel very pumped or stronger in the gym, just more alert, but also kinda nervous and speed. Then towards the end of my 60 min work out came the headache, not very strong one but persitent. At home i realized that my heart was beating abnormally fast, even while resting, it felt so for a few hours ( drank Jacked at 2pm and went to bed around midnite!) Basically i've been feeling like shit since i drunk Jacked and it's been 3 days. I have constant lingering migraine in the back of my head, i feel tired and a bit dizzy at times0.I aslo noticed sinus/gum paina and teeth sensitivity (all related) for the last 3 days.Basically it feels like a hangover that has been lasting for 3 days. (Today it's sunday,and i'm consulting a gp tomorrow at the first hour, really worry about heart and neuro problems!!)And i repeat i only drunk one small scoop of powder mixed with water. I know that this product has been heralded as the best pre work out, but be aware that there could be some unpleasant/serious side effects due to the presence of 1,3-Dimethylamylamine=Methylhexaneamine=geranamine, mixed with possibly way too high dose of caffeine. In 2009, the World Anti-Doping Agency added methylhexanamine to the 2010 prohibited list...period just goole that chemical and you'll find that that Serious adverse effects including headache, nausea, and stroke have been reported in recreational users of these products. People will tell you that it's only dangerous when used in high dose and mixed with alcohol, and that people who had serious side effects were unhealthy partygoers and i'm the proof that it is dangerous for healthy people (no caffeine, no drugs, no acohol) i have used many other products in the past years: celltech, size on, no x plode, green magnitude, superpump, kealkalyn, etc and never have i felt to sick.

After hearing all the hype about this product i decided to give it a try to safe some money. Ive taken nano vapor and no shotgun which both are too much money, jacked is great for the price. The only problem is it really depends on how your body works. I take anywhere from 1 to 2 scoops depending on how much ive eaten and i feel like im on drugs, crack or cocaine.It gives me a euphoric feeling and i can get more reps, not really more weight im just able to pump out more reps. I miss the No shotgun tingles and being able to lift heavier weights on days im not 100% but it all depends on how your body reacts to it. No shotgun works for me way better but for you jack3d might the bomb. Side effect for me wasnt worth it. 1,3 dimethyl is actually a nasal decongestant, and for me it made my nose run like crazy and dried out my throat. When i come off of this stuff it gives me sinus headaches. My girlfriend also noticed that i am more of a dick than usual and i get argumentative. but it all depends on how it works for, so i dont see why anyone shouldnt give this product a try.
