Thoughts on the Product!
Flavor Name: Black Cherry
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.

This is an amazing product! - This is not a paid review I'm an actual consumer -
Flavor Name: Black Cherry
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.

Helping me so much!
Flavor Name: Black Cherry
32 year old woman here, started using this Nitraflex by GAT to help with my workouts, but I've used it before work at my physically demanding job on mornings where I feel like I "need" coffee. In fact, I had bumped up to 4 shots of espresso in my cappuccinos and I realized I needed something else. Heck, I was no longer drinking coffee because I enjoyed it, and I have been wanting to find something so I could go back to really enjoying coffee again and not being a slave to it, but with all the sugars and bad choices out there, I was truly left wanting. Nitraflex has been a godsend. I get the energy I need without jitters or feeling like I need something in my stomach because I'm queasy from acids, my mind wakes up and my body wakes up. If I take three quarters of a scoop around noon or if I have half a scoop in the morning and half a scoop in the afternoon, I feel energized the entire day. Like, able to work out and make dinner for my husband when I get home from work and that was not doable before. The only downside is I get this burning tingling sensation on my lips sometimes throughout my mouth when I first drink it but it quickly fades. No other rashy allergy symptoms, so I don't know what that's about. But it doesn't bother me. I'm using the black cherry flavor which at first I thought tasted disgusting LOL but really it tastes just like Cherry Kool-Aid with no sugar. I am very happy with this product.

I didn't know what to expect and I went into it with a pretty open mind
Flavor Name: Black Cherry
I have been using this stuff for about 3 weeks now. Having never taken any sort of stimulant or other type of pre-workout supplement before, I didn't know what to expect and I went into it with a pretty open mind. I was a little biased due to reading product reviews, and I was sort of expecting to tear my locker off its hinges. First off all, the black cherry flavor tastes amazing. Ingesting the recommended 1 scoop is no problem, even with as little as 16oz of water. If it wasn't dangerous, I would drink this stuff all day. I experimented with a few different times of taking it: 20 mins before workout, 5 mins before workout, and during the workout (which for reference is usually about an hour). The results were pretty consistent. The only wonky day was the very first day: I crashed hard about 45 mins in, but I blame this on having never taken any sort of pre-workout stimulant before (it hasn't happened since). Second, their claim of boosting bench press of 10 pounds in 2 weeks is reasonable in my opinion. However, this isn't just some magical powder that makes you stronger, you have to use the extra energy it gives you to its fullest. Do that extra few sets, push your limits, etc. Third, the assumption that I would go full-on beast mode and rip my locker apart is completely wrong. It's less like becoming a rabid animal, and more like just having more stamina. I feel like I am able to squeeze in 1 to 3 more sets of each type of workout before exhaustion, which to me is a really big plus. Overall, this product works great and I highly recommend it. It would be 5 stars in my opinion BUT I have to take off 1 star because, like any caffeinated beverage, it makes me have to poop uncontrollably. So now I have to fit a poop sesh into my routine (as it always comes at the wrong time), but I am okay with it for now. If you do not experience this type of bodily reaction to caffeine, then ignore this paragraph completely and regard this as a 5 star product. Happy lifting!

Literally the strongest pre workout ever made
Flavor Name: Black Cherry
Wow! I've been lifting weights for about 16 months now and have tried over 15 different kinds of pre work out. This one is a home run! 350mg of caffeine per scoop, plus over 7,000mgs of "other stuff" and a good dose of niacin get you feeling pumped. I've never felt so focused and energized on a pre workout before. This stuff makes me feel like I rule the world. I take just one scoop and feel the tingle in my face within a few minutes. The drive to the gym is amazing after having a glass of this pre workout. In my expirence as long as you work out hard and drink plenty of water there is no crash. However it can be quite rough on an empty stomach. I suggest having a protein shake and some carbs a half hour before drinking the GAT and then head to the gym! Take with plenty of water and stay hydrated while working out. Great product!! Would recommend!

Got me going hard core!
Flavor Name: Black Cherry
Wanted to give it a try, Ive been using NoXplode and thought Id cycle off it for a while. Like this one a lot-no crash so far, first time using it I had three hard hours behind me and still felt like going at it more! No headache, did have some stomach related runs-no biggie tho. New Fave!!! Had to add- just third day using this, no stomach issues, still no crashing, no headaches. Reminds me the of old Ultimate Orange-in that YOU BETTER HAVE SOMETHING TO DO WHEN YOU TAKE THIS!!! Three hour workouts and I still want to do more! Hope you get the same results Ive seen-cause so far this stuff rocks for me!⚡️⚡️⚡️⚡️⚡️

Quality Fail
Flavor Name: Black Cherry
Ive been using this product for several years and was my top choice for pre workout. It wasn’t until my most recent purchase that the product tasted different, almost like it had laundry detergent in it, not only that but it started giving me really bad headaches and brain fog. Hope quality checks aren’t cutting corners. Real disappointed as it was one of best pre workouts I had used. Considering taking a sample to a private lab to have to tested. Keep you all posted.

The only pre-workout I purchase.
Flavor Name: Black Cherry
This powder lasts me about a month of workouts (7days a week) and Amazon says I've purchased it 35 times. I think that pretty much says how I feel about it. It is definitely one of the stronger mainstream pre-workouts I've tried and I've been using it consistently for years now. Black cherry is my go-to flavor. I've tried orange too, which I dint like that much, but I've never liked any product, supplement or food, that is artificially orange-flavored, so I wont hold that against them. I originally chose this pre-workout because it has a high caffeine content and it even throws in a few little things that gymrats like me like (i.e. very mild test booster). My main profession has been managing and running health clubs, including selling workout supplements so I am around a lot of different pre-workouts very regularly. This is the only pre-workout I recommend to people since they stopped selling Savage Roar on amazon, which I was using before Nitraflex. As long as you dont need a pre-workout with a ridiculous 600mg-like caffeine content, this is definitely the stuff.
