I used VPX NO Shotgun V3 with the Synthesize stack for 30 days in November/December and noticed some improvements to overall mass gains and strength. I am a big body weight exercise guy (e.g., push ups, pull ups, etc...) and this helped me push 1-2 extra reps and get me through a long 24 set chest and back workout.
But, I had good pumps, but not has consistent with the kre-alkalyn and Jack3d I am using now.
Good points:
1. Relatively Inexpensive on Amazon (~$35)
2. Good Pumps
3. Good Sustained Energy
Poor points:
1. Makes you somewhat jitterly at the beginning of your workout.
2. Has a whole wide variety of ingredients, which is sometime worrysome, with about 5 differnt types of creatine.
3. Not has solid as other pre-workout drinks such as jack3d.
4. Can't use kre-alkalyn while using Shotgun since the amounts of creatine in Shotgun are 10g+
Overall this product is a middle in the road for me. For the money, I now perfer Jack3d and kre-alkalyn. It is cheaper and more effective for my body.

I love this stuff and it gives me a great pump and engery. I especially love the high protein content you get with it right before your workout. Unfortunately that protein comes at a cost, which I totally understand however some months I just cant swing it when I can get 45 servings of somethign like jacked for less. I do recommend this though and it worked great and taste great, I would pick it first over the others I use if it didnt cost more.

One of the first NO supplement me and all my buddies tried in highschool in our starting days. And for some reason it has always worked great for me other try and bash it but the taste in most cases is amazing, never needed more then 1 scoop to have pins and needles all over and kicked in instantly for great pumps. Somewhat expensive but is a great product if you can find on sale and especially since there is approx 28 servings or so. other then that awesome product.

To start off id have to rate this as my #2 Pre-Workout. I heard of this from a friend who liked Jack3d and black powder so i decided to give it a try and holy crap was it worth it.

Effectiveness: 8/10 I would take this 30min before i would hit the gym and around the 15min mark i felt the energy slowly kick in. At the 30min mark it was fully kicking. I would hit the gym with full force the moment i walked in the door and it would last for almost 2hrs. Why i gave it a 8/10 was because the downside of this is that it can make you too hyper so if you go to hard it may make you dizzy and sick

Value: How much i got vs the serving size was decent the scoop wasn't huge like some supps i have had before. I ordered it on sale so it was around 25$ and it was worth it.

Tolerance: 7.5/10 I was surprised by this product because usually about 1/2 way through my pre-workout supps i would have to up the dosage like 3 scoops with Jack3d and NO-Xplode. After using about 3/4 of NO Shotgun V.3 i needed to take 1.5-2 scoops and by the very end i had to take 3 but for some 3 would kill them because every one has a different tolerance

Overall: 9/10 Like i said this ranks as my #2 Pre-workout (#1 being Jack3d and #3 being super pump max) If you can snag it on sale give it a try or even if its not just go for it. You will notice a difference at the gym big time (just dont take 3 scoops right off the bat like some people do because that can push your body too hard if you are sensitive to stims)

NO Shotgun is a good pre-wo with muscle building in mind.

Effectiveness(8) - The ingredients in this supplement are novel, and effective. The whey isolates, creatine blends and other compilations provided an increase in muscle growth and recovery. Focus and Drive were unbelievable, but it never failed that I got a caffiene headache at the end of my workout. I have never taken NO Synthesize, but I imagine that it could solve this problem.

Taste/Mixability (6)/(10) - Shotgun didn't taste too good. I used the Exotic Fruit....bad mistake. While it tasted bad, it mixed easily with no complications.

Value (6) I got what I paid for, but was still left wishing for a lower price. I paid $ 32.00 for 28 servings - a price that I wouldn't tolerate except from a good product such as this. However, most prices are much higher, and Drive the value down to a 6 = still worth it, but not cheap.

Conclusion - A good muscle-building pre-wo. if you are tolerant to caffiene, you might want to use caffiene-free NO Synthesize. Aside from that, I would definitely recommend this supplement to anyone that stumbles across it on sale.

Tried NO Shotgun V.3 for the month of May. here's my review.

Taste: Definitely better than most. I got the watermelon flavor, it wasn't bad at all. I'd give it a 9/10.

Side Effects: Early on somewhat of an upset stomach, don't know if it was directly from the product, but they seemed to stop after week 2.

Notable: After mixing the supp, it was quite foamy. I usually shake it in a bottle of water, but even when stirred it still foamed.

Other Supplement Taken: I got suckered in to taking NO Synthesize as well. Which at times gave me more energy than the Shotgun, unfortunately I drank that at the very end of my workout.

Gains: None/Minor. Didn't notice really any changes. I'm 5'8", 168lbs. After 'cycle' I'm now 170lbs.

Exercise: I get a good mix of weights and cardio in 5 days a week. Usually 30 min. of cardio then 45 min of legit lifting.

Diet: Typically a protein rich diet. Eggs, PB, and chicken for dinner. Weekends I usually threw in a few beers, nothing out of the ordinary.

If you're on the fence about trying this, I'd give it a try, it may work for you. It's relatively cheap, I got it for $30 online. I've had better results with Jack3d and 1.M.R. and even NO-Explode.

I got a sample pack of both this and synthesize at the arnold one year. So i tried them that following week and had the greatest pump ive ever had. So, obviously i went out and bought both synthesize and shotgun the next day. throughout the jug of it my pumps varied in intensity. i liked this enough to purchase two more jugs of it over the following couple of months. i decided not to purchase the synthesize and my pumps didnt change without the second supp with shotgun. although i think this is a good, not great, pre workout drink, i have not gone back to it in quite some time. i liked NO Shotgun, but didnt love it. i guess it could be from the fact that the sample pack i had gave me the greatest pump ever, and i didnt wanna stop working out. then i bought the jugs of this stuff with the expectation of it being just as good, and it wasnt.....but it was still a solid purchase. i actually liked the taste of it. i tried both the fruit and watermelon flavors and both, although they tasted kidna odd, didnt taste bad at all. i would recommend this product to anybody looking for a good preworkout drink. if you order online you can find it much cheaper than the price you would pay at GNC. the only PWO's that i like more than this are, NO explode and jack3d. happy intense workouts fellas!

I've used NO Shotgun a few times now and I've got to say its one of my favorite pwo's. I've used others like Jack3d and Animal Pump but i just keep coming back to it.

Effectiveness:
I take this stuff 30 min before a workout and by the time i get in the gym im 100% focused on what im doing. I love the feeling i get from the Beta Alanine on the Drive to the gym. Definately gives me the Drive and focus to get through rough training days, and i definatley feel like "pumps" increase when i take this product. On days when i work in the AM and dead tierd this product definatley helps get me up and to the gym

Taste:
ALOT of people hate the way this product tastes, in my opinion its not much worse than most pwo's and if you just suck it up and chug it its not bad

Negatives/Sides:
For me theres not much to mention, the biggest thing is the supposed 18g of protien per serving...if you read the serving size it doesnt add up but, at least in my opinion, its not a huge deal. The only other main issue is tolerance...because i cycle products with stims it usually only takes 1 scoop to feel effects when i start using it but with this product i feel like you develop a tolerance very quickly and by the end of the container im usually up to 2.5 to 3 scoops to really feel the effects...im also a very stim tolerant person. Also price can be an issue but if you shop around it can be found for very reasonable prices

Overall:
I really like this product...what i want from a pwo this product delivers. Dont get me wrong i think Jack3d is a great product but i think its sometimes overhyped as being much better than any pwo and i personaly feel that NO Shotgun is just as effective

No Shotgun, what can I say, my favorite pre-workout supp and my go to pre-workout in the future.

Mixablity & Taste: the flavor I tried was black cherry. im not someone who puts taste 1st but someone who does i would say you would have a tough time getting through a jug of this. maybe its just this particular flavor but for me taste is not important. as far as mixablity goes shotgun did foam up quite a bit. just let it settle and whack it down.

Value: this supp is a little on the high side on alot of websites. i got mine on Amazon for $27, so the price I paid for it was good. definetly worth it in my eyes. just have to shop around a bit. also there is 28 scoops in a bottle. serving size is just one scoop. so this will last almost 2 mths.

effectiveness: this is where the 10 was earned. I had great workouts with this. the beta aline content in this really kicks in and makes getting through a tough workout easier. the pump was just out of this world. consistinatly thoughout this supp i had a sustained pump. the COP and Redline are effictive in this product. Redline keeps you in that fat burning type of state.

Overall: this is my favorite pre-workout supp so far. i enjoyed this and will definetly give it another go in the future. i have taken Jacked, 1mr, sp250, and Muscle Marinade. so far this one is for me. i have a bottle if Noxipro im gonna try when i cycle of stims. looking foward to trying that with the positve reviews on here about it. all in all i would recommend this pre to anyone.

The only pre-workout I truly enjoy anymore. I really enjoy the level of pump I get and the taste is pretty good compared to most of the other supplements I've tried. I've taken approximately ten full tubs since first trying this product back in 2007.

I find this product most effective for cutting weight. I cut from 248 to 179 in 5 months thanks to the added protein, energy and Redline in N0 Shotgun.
