Wow. This stuff is amazing. No fillers, the taste (lemon-lime) isn't overwhelming, and I can work out solid for 1.5 hours and still feel like a beast. I've taken NO-Xplode and Black Powder, and I find that Jack3d provides more energy, while something like Black Powder gives me more pump. This is why I mix a scoop of Black Powder and a scoop of Jack3d and get totally effed at the gym.

I've come to notice that if I take jack3d later in the day, it really messes with my sleep, and I contribute that to the DMAA in it, which is a stimulant. I just finished a bottle and I notice my tolerance was going up. On days that I was taking just jack3d, since I like to mix it up, I moved up to 2 scoops towards the end of the bottle.

So all in all, awesome for energy in the gym, only somewhat decent regarding pump. But I still give it a solid 9. I have yet to try out 1.M.R, which I will be getting next week, and can find out then which is better for me.
BTW I didn't get a 'crash' that so many people speak of, this could be that maybe I am not just prone to the type of thing, and that I work out after I get off work, so 'crashing' really doesn't matter for me.

I havent used any supplements in the past two years, and my workout routine has been pretty mediocre and unstable. I wanted a supplement to help me get back in shape quick so that I can start taking muscle building supplements. Anyway, I read that everybody was giving this supplement exellent reviews so I decided to give it a try. The first time I used I was like BAM!! a ridiculous amount of energy that I have not felt in a long time, specially when I am working out. I just started working out about 2 weeks ago, (post date) and usually my workouts were lethargic, tired fighting with my body to get on the next set, but Jack3d made me workout with a ridiculous enthusiasm. I couldn't stop working out, I felt so much energy and the pumps were ridiculous. My myscles felt like they could go the extra rep, after the extra rep, after the extra rep lol. I was sweating like crazy, prolly cuz of the caffeine, however I don't sweat not even working under the sun haha.
I reccomment this to everybody that needs more energy in their workouts wether you a beginner or already deep into fitness. This is a great supplement. Just make sure you don't use a lot of it each time, and try to skip days on it so you don't develop tolerance to it quick.

Jack3d was my first experience with a pre-workout supplement; however I did not have the same overwhelmingly positive results as many of the other reviewers. I will preface this review by saying that I’ve never been sensitive to caffeine and, up until only recently, drank coffee every morning.

I have finished two full tubs of this product – 1 fruit punch, 1 lemon-lime. At the end of the second tub, I was taking 3 full scoops of Jack3d, on an empty stomach, roughly 30 minutes prior to exercise.

TASTE & MIXABILITY: 6/10
Lemon-Lime: 5/10
Fruit Punch: 7/10
The fruit punch flavor would more aptly be titled as pina colada. The smell reminded me of suntan lotion. Not bad, but certainly not something I looked forward to drinking. The lemon-lime however, I did not like at all. It had a very medicinal quality and an awful acidic aftertaste. Additionally, neither flavor mixed particularly well in any of my shaker cups or with a spoon. The mixture was always very grainy and the product did not fully dissolve. The last few sips always contained way more of the powder then the rest of the drink, and it was clear that some of the product had clung to the sides and bottom of the glass, making me feel like I was never getting the full dose.

As a comparison point, I have also tried 1MR, White Flood, and Assault. All of which I would say taste better and mix more easily than Jack3d.

EFFECTIVENESS: 7/10
Pump: 8/10
Energy & Focus: 6/10
I think the most prominent effect of Jack3d, for me at least, was the pumps I got after taking the product. Almost immediately into my workouts I would feel much bigger and more vascular, and the sensation would usually last well after I finished exercising.

Unfortunately Jack3d only gave me a slight boost in energy and focus during my workouts. I would feel an itching sensation almost immediately after drinking Jack3d, followed by about a 30 minute period where I was slightly more energized. Again, my tolerance to Jack3d may be in part that I am tolerant and accustomed to regular consumption of caffeine, it may be that I am a naturally energetic person (I do public speaking and presentations for a living), or it may be because I work out in the afternoons when my body is already warm and my mind awake.

Again, as a comparison point, I will say that both White Flood and 1MR gave me greater energy, focus, and motivation than Jack3d (I am currently taking White Flood). It is not as if I am completely tolerant to PWO’s, but for whatever reason Jack3d’s formula simply didn’t work to its full potential for me.

VALUE: 9/10
In terms of cost, Jack3d certainly tops the list of great affordable products, provided you only need a single scoop per serving. At 45 servings a tub and a cost of only around $25, Jack3d is quite a bit cheaper per dose than many other PWO’s, i.e. Dark Rage, Assault, & NO-Xplode. If, however, you are like me and need the full three scoops per serving, then Jack3d is not quite as cost efficient. In my case, I only got 15 servings from my second tub of Jack3d, which ended up lasting me around 3 ½ weeks. For roughly the same price I was able to purchase a 50-serving tub of White Flood. Even at 2 scoops a serving, this is still 10 servings more per tub.

OVERALL: 7.5/10
I am not saying that Jack3d is not a great product – it clearly is for many people. However I think this product is often considered the “end all, be all” for pre-workout supplements. This may not necessarily be the case for some people (myself included). No doubt Jack3d is a good choice if you’re new to PWO’s and want a reliable (and relatively inexpensive) product, but I would also encourage those new people to try a few other products as well and not simply accept that this is the best PWO.

I have always given the edge to USP Lab's products. But i must say i have tried most their products, out of all of them, jack3d takes the cake.

Effectiveness- 10/10: I have tried everything, Noxplode, SuperPump250, White Flood, Assault, Black Powder, you name it. But out of all the PWO supplements i have tried jack3d has never failed me. It always gives me the energy and focus i need to get through my workouts, and everytime i take it, it always feels as if i were taken it for the first time, its effects never wear down. I have yet to experience any feeling of light headedness or dizziness.

Taste-9/10: I was okay with the old lemon lime flavor, although it was a little too bitter for my taste, but the new fruit punch is actually very delightful. I now have no hesitation of tasting it no longer, the new flavor is just like pina colada! only just a little bitter, but nothing to look poorly upon. Overall taste is great!

Value-10/10: This is probably one of the best deals on a supplement period! For 30 bucks for 45 servings is just simply cheap for such a great PWO supp.

Overall-10/10: Overall, jack3d IMO has little to no flaws at all, effectiveness is awesome, taste is very good, and the value is unbeatable. Overall, i would definitely recommend this to anyone who wants a grade A quality and a great valued supplement.

This review probably isn't much needed, as jack3d has already become a leading product. Now, I don't like just giving products all 10's just because they tasted good, or if they work, but this deserves it. Before trying this I was taking NO Xplode and I couldn't stand the taste. I'd have to sip it little by little. And I didn't appreciate some of the side effects. Jack3d has all the basic, pure ingredients I want in a pre-workout. I actually enjoy the taste. I can chug it down without gagging. I use the lemon-lime and it tastes like watered down Kool-Aid. After about 5 minutes, my lips become tingly from the beta alanine, and after 25 minutes my legs start to itch. Once again, this always happens with beta alanine but it doesn't bother me & it goes away. There's no artificial fillers. Citric acid & Natural lemon lime flavor. And the price is phenomenal compared to others. I finished a cycle with 1 container of jack3d and still had some left in it. About 1.5 scoops does it for me, and it gives me the best workouts every time. I also love since it's so pure, the container is very small and light. It's not some big 5lb container. I've never had any side effects other than the beta alanine (itch), but even when I cycle off I still use B.A. No crashes at all, ever. I remembered how much I loved this as I just started taking again after a month off. I'd say just don't overdo it or think you NEED 3 scoops. The feeling, the natural energy high I get lasts a long time too. I've gotten some of the best workouts by taking this & then doing a full hour of total body stretching to become completely warmed up, and then follow that with intense lifting and cardio, all the while be able to lift the same weight on the last rep as the first set. Some cons...uhm. None really. If you take it in the evening you will probably miss some sleep but that's not the products fault. All in all, probably the best pre-workout supplement for anything..cardio, lifting, sports, you name it.

So I got a tub of this for about $25 and let me say that it was probably one of the best supplement buys I have ever made. The only way I can describe the way it makes me feel is like a wild animal who broke out of his cage. I literally have to make myself leave the gym when I take this stuff. The pumps were good but not spectacular. 2 scoops does the trick for me so its a little less than a month supply for under $25. It's also nice to see a supplement that doesn't use the kitchen sink approach by putting in a bunch of under dosed extras. Not only does this supplement do wonders for weight training but I take it before MMA training on non lifting days and it keeps me ferocious throughout the entire two and a half hour session. I just ordered a 3 pack of this from bodybuilding.com and plan on being a long time user of this product. Just too bad that you have to cycle off of it once in a while. I got fruit punch the first time and it wasn't the greatest tasting liquid I have ever drank, but I also don't take pre workout supps for the taste so it doesn't effect my opinion of it at all. If you work out in the evenings its probably going to keep you up since the energy is highly sustained and doesn't make you crash. There was a lot of hype surrounding this product and I figured that I would try it for myself and see if it lives up to it. Not only did it live up to it for me but it surpassed my expectations completely. Do yourself a favor if you have yet to try this supplement and go get some now!!!

Gave this a 10 cuz I couldn't rate it any higher. By far the best pre-workout supp I've ever taken, and the cheapest. Don't be fooled by the diminutive tub, it has 45 1 scoop servings...which in most cases may be all you really need. On my first does I felt a real good energy rush, but not the kind that makes you worry. I felt more awake, more aware, and more assured of myself then I did on other supps line N.O.-Xplode and Black Powder. This stuff works great for both lifting and cardio workouts. In the gym I was hitting new highs, and in my Martial Arts is was setting new standards. The pumps I got in the gym were awesome. On arm days it looked as if my arms almost doubled in size. The best part was the ingredients, or lack thereof. Jacked keeps its list minimal, keeping only the stuff you really need. No food colouring, no over the top flavouring, just stuff that works. The taste was great as well. It actually tasted like a lemon-lime drink would, while most other supps just ball-park the flavour. It mixed very well, which is a big problem for me with N.O.-Xplode and Balck Powder. I tried the red label, which is lemon lime me thinks, and it more than exCEEded my expectations. Some are saying the new blue label (fruit punch?) is better formulated, so I might give it a try. The only probelm with taking this was it made me very skeptical of other prodcts. If this stuff costs around $25-$35 and works wonders, why should we pay $55-$75 for stuff that may not?

I tried this for a change from Super Pump. I liked that the scoop was so small and not a lot of product was used for each serving. The taste was ok but not as good as Super Pump.
There was a couple of times that I did get dizzy when I used it but nothing over the top.
I got good energy and focus from this that was a slight bit better than Super Pump but didn't get the same pump from it.
I really liked it and will use it again for a cycle to break up the Super Pump use.

Jack3d is an "alright" pre-workout supplement. It has minimal ingredients which I greatly appreciate in todays kitchen sink approach to pre-workout drinks.
When I first took jack3d, I used two scoops and it was too much for me. I was sweating profusely and had to slow down my tempo when I was lifting just to feel normal.
When I used the 1.5 scoop dosage It only did what I would expect from taking creatine, Beta Alanine, and tons of caffeine.
Even when taking Jack3d I would often feel lethargic and spaced out. I would have a caffeine rush but I would feel very spacey and unfocused which made me like a zombie in the weight room.
This is however the best pre-workout powder when on CKD because of its zero calorie content.
I would however choose Animal Pump in pill form in the future for pre-workout during CKD because of its amazing pump and energy effects.
Jack3d also tastes aweful, it only tastes better than NO-Xplode which I will rank at the bottom of the list in pre-workout taste rankings.
I will add that I like adding in watermelon flavored SciVation Xtend (BCAA's) into my Jack3d and this offsets the bitter taste and makes my pre-workout drink much more enjoyable.
Co-workers of mine have also tried Jack3d and the consensus is that its nothing special or groundbreaking, its just a mediocre zero calorie pre-workout that pretty much equals its cost with effectiveness.
If you have any questions about Jack3d or my usage please PM me rather than commenting.

I have to admit, I was skeptical trying Jack3d for the first time way back over the summer. I was convinced enough by the information I found on USP Lab's website to give it a shot. The first day I took it, I only took 1.5 scoops because I was SCARED TO DEATH by all the warnings on the packaging. Needless to say, 1.5 worked like a charm. I literally was in a different state of mind. My friends came up to me and I had a tough time paying attention to what they were saying because I was so focued on tearing up the weights. The pumps were definatley there, but I didn't feel it too much after the first 30 min or so. It did delay, fatigue, increase strength, and give me that Beta Alanine tingle (which I CRAVE for some reason). I took it until it ran out using anywhere from 1.5 - 2 scoops per workout. The taste did get a bit unpleasant after a while, but compared to other preworkouts Ive tried, I can live with it. I also began to become immune to the stimulant affects because I was consuming so many caffinated beverages over the summer. I was also pleased with the price and ingredient profile. When they switched the formula and made the 250g container, I made sure to get some. For the first time ever, I took 3 full scoops and the experience was OUT OF THIS WORLD! I cut all other caffinated beverages 3 days before that and when I took the Jack3d, it felt so good. I really don't know how to explain the full feeling, but I kind of felt "weightless", at least a lot lighter on my feet. My reflexes and focus were definatley increased, and the tingle was definatley much more enjoyable. Needless to say, my strength did increase and I've been experiencing some really good workouts using 3 scoops 4 times a week. It lasts me 4 weeks at that rate, and with only a $27 price tag at Vitamin Shoppe, it's finally a legit product I can afford to cycle properly. The only problems I have with this product is the lack of pumps. I know some people claim to have great pumps with this product, and power to them, but I've only experienced slightly above average pumps at best. I'm only a little more vascular while working out on it, and honestly, I'm still on the search for the preworkout that will do that for me. I'm also dying to try a new flavor if they would EVER COME OUT WITH ONE! The lemonade is getting old. But my tip to all of you would be to stop all intake of caffinated beverages outside of Jack3d and it will hit you much harder (in a good way). I love the energy, focus, strength increase, and tingle it provides, now they just have to change the flavor and maybe add some more arganine or something to provide better pumps and this would be 10s across the board.
