I am very very very in to fitness and lifting. I have family and friends who work for a mass merchandiser of supplements so I have tried next to everything. Of all the supplements that I have tried (as a female) Jack3d is by far my favorite. Some pre-workout supplements are so intense that I feel like I have no control of my body. Some of them are so intense that they cause me to vomit and throw my body completely out of whack. Others didn't make me feel any different or increase my workouts at all. Jack3d on the other hand, gave me just the right amount of "pump" for my workout. It tastes great (with the exception of sometimes the last swallow) and comes in a few different flavors. It's a great product and for females who are in to lifting, but not into the extreme pump that some other products give, I DEFINITELY recommend jack3d! I've been taking it for months and have no plans to switch products.

I'm very happy with my purchase, I picked up Jack3d about a month ago and I am nearing the end of my first tub of it. It was a recommendation from one of my friends and we have been using it to it's maximum potential. When I get into the gym I use this product and it keeps me pumped throughout. I definitely recommend this over the older version of Superpump 250, it acts as a great pre workout formula. Something to consider when ever using nitric oxide products before your workout is make sure that you are drinking a ton of water to keep it flowing, this will maximize your workout and pump. You can't go wrong with either of the flavors either it's definitely going to be a guaranteed buy for me the next time I am at GNC.

My husband had gastic bypass two years ago and lost over 200 pounds. Since then he has been going to the gym 3 to 4 times a week. After working all day, sometimes he needs a little help to give him the energy to go. He started using Jack3d by USP Labs about 6 months ago and he loves it. The container is small compared to so of the other products. It comes in three different flavors, Lemon-lime, fruit punch and another blue rasberry or something. The Lemon-lime and fruit punch are the best. You just mix one scoop to 4 oz of water. I know most guys take 2 scoops but the company does say not to take more than 3 scoops in a 24 hour period. Take it 20 mins before working out and you get the energy to go workout. You don't get any after effects either. My advice is to drink a nice protein drink afterwards.

Simply put; best no2 on the market. If you don't believe me, look at all of the websites that carry/review this product. Jack3d simply takes no2 to the next level. The stuff works like a charm in giving you that extra boost for working. out. I tried tons of products including bsn no-xplode, but this stuff had me sold. You may feel a little jittery or get headaches though, so watch how much you take. With that said, it added 15 lbs to my bench like it was nothing. In regards to taste, i've had the lemon lime and the tropical and the lemon lime is definitely better. It basically tastes like flat sprite. The tropical was a little tough to bear at times and made me nauseous after a while. The lemon lime is a great choice tho

Jack3d is the second pre-workout supplement I took. The first I took was No Xplode and it works pretty well at first but soon it didn't have much of an effect on me. A friend of mines recommends me to try Jack3d and I brought a tub. The first time I took it I had the sickest workout ever. Jack3d gave me a ton of energy and felt like I could go on forever. During that workout I hit a few personal records and even after my workout was over I felt as I could keep on going! I have been using it for about a week now and I don't feel as it has lost its effectiveness. The crash from Jack3d isn't too bad. Nothing like an energy drink crash but it's there. I highly recommend anyone to try this out, you will have of your best workouts!

First I want to start off by saying I LOVE this pre-workout. I have tried many pre-workouts; Muscle Pharm Assault, which had a LOT of ingredients and fillers, including maltodextrin, which is what you don't want in your pre-workout. Not only that but it was INCREDIBLY sweet, and made me sick, which is not exactly how you want to feel before a hardcore workout. I've also tried SuperPump, which was quite good, even though it had some fillers. Now, onto the real topic, Jack3d. This is generaly the best pre-workout you can get on the market today. No fillers, no ingredients added for flavor, no artificial colors, dyes, none of that stuff. It has nothing but real ingredients, in which USP labs backs up 100% for each ingredient in Jack3d. First time I took Jack3d I was absolutly AMAZED. After I took it, it took about 10-20 minutes to kick in...and WHAM!!! It only has somewhere between 60-80 mg of caffeine (USP labs dosen't tell you but that is what I hear) so therefor there is no jitters. The real reason why it gives you this incredible energy is the other ingredients that mix with the caffeine. Make no mistake, this is POWERFUL, and extremely effective. I had the most amazing workout of my life and after an hour straight of working out with only 30 seconds rest between sets, I could have went for more. I felt the most amazing pumps of my life, and was incredibly sore the next day. I have continue to use Jack3d, and have went through about 2 tubs of it, using it about 3 times a week. I will never use another pre-workout again. Hands down, best pre-workout on the market. Start getting real results with Jack3d.

I absolutely hate running, but this product somehow gives me the umph I need to knock out 3 miles every morning.  I had the grape flavor, and it's fantastic.  I usually mix a scoop with about a half cup of water or powerade or anything, and it's just fine.  No problems with the flavor at all.  After about 10 or 15 minutes you start to feel the energy...I found myself pacing after the first time I used Jack3d.  Once you start working out, you'll feel tingly.  For me, from head to toe I feel kind of tingly...especially when I stop running at a stop light or something.  It doesn't hurt or anything else, just a weird tingle that lets you know that the stuff is working!  Keeps you going for about an hour or so.  I definitely have never had any stomach problems with this product, nor have I had any problems with it losing it's effectiveness over time.  Just don't feed yourself so damn much and you won't have that problem.  I stick with 1 scoop every time and that's plenty.  Great stuff, will use forever!

I was looking for something to give me a little extra boost at the gym when a friend recommended that I try jack3d. At first I was skeptical at the claims that were being made all over the internet. Upon receiving and trying this product I was quickly turned into a believer from a skeptic. It gave me such a pump that even after 2 hours of weight lifting I did not feel tired and did not want to leave the gym. The energy from two little scoops was absolutely fantastic. I took the recommended two scoops thirty minutes before arriving at the gym. Within ten minutes of taking it I could feel my muscles tightening up and a desire to use them. During the first week of using jack3d I saw minor gains at the gym but the following weeks the minor gains turned into major gains. I am very pleased by the results I got from jack3d. The only bad thing about jack3d is that you have to stop for a month after you have taken it for two months. I guess this is so that your body does not get used to it.

I have tried many preworkout drinks (NO-Xplode, NO Shotgun, 1 M.R., etc.) in the past but none have compared to the results I get from this product. When you first receive it the bottle and scoop are so small that it seems like some kind of a joke. But it is far from a joke (be sure to take note of the blackbox warning on the bottle)! I tried 2 scoops my first time and I felt as if I wanted to tear the whole gym down. I was extremely focused, motivated, and full of energy and even after 2 hours of strenuous excercise, I felt like I could go on for much longer. I have only tried the Lemon-Lime and Fruit Punch flavors and although both are bearable, I would much rather prefer Lemon Lime over Fruit Punch. Furthermore, this product is much cheaper than most preworkout drinks out on the market and I also feel that it is more effective. One thing I did not like about this product was that I would get cramps if I did cardio (even if I drink tons of water), this is the only preworkout that has caused this.

The first time I tried jack3d I was amazed. Great pumps, great energy. Does not taste bad and does not require alot of liquid like other pre workout supplements out there. I started off with 1-2 scoops (the tub has 45). In terms how I felt at the gym, the answer is simply amazing. You get this tunnel vision like focus and you actually want to lift weights. Taking jack3d actually made me look foward to going to the gym and lifting weights. These effects do not last forever though. By the time I got through my second tub I was taking 3 scoops at a time and barely feeling the effects. It is easy to build a resistance to this product and that is the only downfall. The other problem is that it causes you to crash heavily after your workout. You won't feel like doing anything and will have a severe tiredness after your workout. This product also has caffeine in it so if you are stimulant sensitive then avoid taking this product.
