Best pre workout
I used to live in CT and actually worked right up the road from GAT’s office. They sold this in just about every gym I went to and when I moved I really missed having it around, thankfully I found it on Amazon. This is one of the few preworkouts that’s consistently worked for me. The mix is solid and I didn’t realize until after a couple weeks of taking it that it had boron, which I think definitely made a difference. Blue Raspberry is hands down my favorite flavor. It mixes clean, no clumps and unlike some other brands, the quality hasn’t dropped off as they’ve gotten more popular. Very effective.

This is an amazing product! – This is not a paid review I’m an actual consumer –
This is one of the best pre workouts I’ve used in a long time. I’m a “stimulant junkie” and get a great feeling with Nitraflex. No tingles, great focus, good energy, no made up ingredient names for marketing, great pumps and no crash. To see if it was me or the product, I purchased a different pre workout to find out. Sure enough the other product I bought gave me uncomfortable tingles and left me lagging through out the remainder of the day (I used it for a week for my own study). I’m an early morning gym guy, so feeling sluggish wasn’t good for me. So I turned around and immediately purchased my third container of Nitraflex. Even if you’re an evening gym goer this product is still a good choice. It’s a clean transition from your “high” to being on your natural energy. So it won’t keep you up all night. I also tried it in the evening just to see if it would keep me awake. Over all; the taste is great (I’ve used fruit punch and black cherry both were good), the results for the use of a pre workout are legit, no crash, clean energy (no tingles or jitters), and the price compared to other pre workouts can’t be beat. I’m making my comparisons based off uses of C4 Ripped, Beyond Raw LIT, BPI Best Pre, and Nitro Surge to name a few of the previous products I’ve used. As always, test your tolerance first, know the ingredients, and be sure to cycle off at least a week between the end and start of a container.

Thoughts on the Product!
Thoughts on the product-Ill start off by saying I am 21 years old, 5’10 and 183-185 pounds, I have been working out seriously for about 2 years now and I have tried many prework outs. Some of my favorites being Superpump max, SAN fierce domination, and a lot of the small scoop high stimulant products like craze, so I have a high tolerance for stimulants.First of all this was my first time using any GAT product and I must say I have been very impressed. Ill start with the flavor, I chose Green Apple flavor, which was very unique tasting compared to other green apple flavors I’ve tasted, it gave off a very sour aftertaste but was sweet as well, the closest thing to compare it too would be sour candy which was a plus for me, I thought the flavor was outstanding. One thing I also noticed was compared to other pre-workouts that sometimes can take 20-30 minutes to really kick in you start feeling the effects of Nitraflex minutes after you take it , which is a plus for anyone in need of very quick energy.I personally have never been a fan of the tingles that Beta-alanine provide, however this preworkout features beta-alanine (as carnosyn) dosed at just the right amount, it was not too overpowering to handle. When it comes to vascularity this product is hands down the best I have experienced. The pumps were outstanding and it was a product that left me feeling pumped even hours after my workout, it really works as a great vasodilator where some products claim to fail this one does not.Energy wise it was great, this product contains 325 mg of caffeine in each scoop, as well as a few other stimulants, so it is not for someone who is very stimulant sensitive, but it is for someone that needs a great boost of energy before a workout.This product also mixed rather well, there was usually no residue left in the bottom of the shaker when I was done drinking it.I also thought this product was unique as a preworkout because it also claims to boost testosterone, using Calcium fuctopyranose borate CFB US PATENTED, although I can not back up these claims nor did I see any significant effects over the past few weeks using the product testosterone boost wise, I must say it has worked well all around as a preworkout.I have just purchased a second tub of watermelon, the flavor is good, but not as good as green apple in my opinion. Overall I really liked Nitraflex, it retails anywhere from $32-$38 and contains 30 servings per container, so that puts you at a minimum of $1.06 per serving which is a little high but if you have the money and are looking for a good pre I would say its well worth it.Rating-Mixability-10Taste-10Price Per Serving- 8Energy-10Pumps-10Overall Rating- 9.6/10

Great product but cant sleep
I really like this pre-workout product. It gives me great focus and energy to power through my workouts. The flavor is good, not overbearingly sweet and dissolves well. I would give it a 5 star rating but I have trouble sleeping when I take this. On the label it says, not to take it 5 hours before bed. I take it when I get home at 5 and I usually go to bed at 11pm -midnight and I have trouble falling asleep. I have learned to take smaller doses and I take it at 4pm now. That has helped with going to sleep but I feel its not as effective during workouts.

Stuff works for me before working out and no ill feeling or side effects!
1 scoop in 24oz of water and 30 minutes later i was buzzing like a chainsaw cutting wood on nitro. I suggest to make sure your 2+hours after having a cup of coffee before drinking this stuff. It was leg day and it was the best leg day i had and i didn’t procrastinate. I couldn’t believe how much energy this stuff gave me. Best part was no crash, but worse part was i over did it. I had the energy to push thru from my 8-12 reps to 16+ and adding another set with no sign of running out of steam. Today was a different story. Took it 6+ hours after my last cup of coffee and 30 minutes prior to exercising and yesterdays you over did it kicked in… So I just focused on core. Sore but not tired.I had no side effects and no upset stomach.If it has the same effect 2 weeks from now i will be buying another container as i train 4 days a week.

Best Pre workout on the market
Great pre workout. I have purchased several of these over the years. I have tried a lot of different pre workouts and always come back to this one. It’s the best bang for your buck. No issues mixing and you always know what you’re getting. Highly recommend

This preworkout never fails me! My body gets used to every other preworkout after a week but this gives great steady energy! Taste is amazing as well
Felix –
The first time when I used it I had tingling sensation and the normal feeling or itchiness all over me. However, the boost of energy that comes with it is amazing. I could lift almost twice the normal weight im used too. Definitely will be buying it again
Chris –
Not too overpowering
Sandeep Sharma –
Guys guys guys.. This is the only review that you need to read. Just came home after working out and for sure, this pre gives you a different high that I have never experienced from any pre-workout before. Could be a case that I have never been a caffeine junkie in my life so that is why it hit like that. But one thing for sure, this will shake your world completely, not only in the gym but also in your day to day life. I am not a big believer in writing reviews but this, this thing has completely hypnotized me. This product definitely has to be up there on the list of things that I will never ever regret buying.

I’m sure some people may actually feel the effects but 320mg of caffeine and it felt like I had nothing, some of my friend took 3 scoops of it so over 900mg and still didn’t feel anything
Justin –
This seems to be a new formula and is pretty weak compared to the original formula. Seems many of the good ingredients have been removed. The ingredients in here are the basics and are not worth it at the same price. I miss the original formula.If you need a good wakeup from the high caffeine content, go for it. Other than that, I can’t even feel the beta alanine or any strength / pump effects from this. It does however taste good, they improved the taste, or possibly it tastes better because they took out all the good but bad tasting ingredients.
