GAT SPORTNitraflex Advanced Pre-Workout Powder, Increases Blood Flow, Boosts Strength and Energy, Improves Exercise Performance, (Blue Raspberry, 30 Servings)

Excellent prime day price. Very very clean product and works great. Feels like testosterone is raised from this product. Pumps and energy feel clean and no crash really noted compared to C4 Extreme/C4 Ripped and even compared to ON brand or Alphalion or GNC brands. This has all types of energy supporting compounds !

Good pre-workout drink without jitters, but awesome focus and pump. Can't beat the price.

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

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.

Quality:Consistent energy and tastes good

One of the best pre-workout I've ever tried. Gets me going with the energy needed for a great workout. Good for a great pump without the strong tingles all over your arms. I feel it naturally increases free testosterone as it specifies but blood work would be needed to verify. All in all keeps me coming back to the gym for another workout. I would definitely recommend this product!

Let me start off by saying I have the highest tolerance for caffeine I've ever even heard of. It will take TANKS to keep me up and going ESPECIALLY in the mornings which is when I typically work out. I've tried both C4 and Assault which took all of maybe 2 weeks to begin wearing off. Nitraflex has been going strong since day one! (Which has been a bit over 4 months)FEELING: I would say the effects ramp into gear in as little as 15-20 minutes but it's very gradual for me. I do gradual strength training for close to 1 hour, anywhere from 4-5 days a week and it keeps me up for the entirety. Starting off, you will feel the itchiness but over regular use that itchiness will dissipate. If I go a few days without taking it then ill start to feel it again but in all honesty I never mind the niacin effects.GAINS: I've been WRECKING my gains week after week with this stuff. I definitely doubt I would be building as much as I have without it. You feel noticeably more powerful (I call it the spinach to my Popeye) and I immediately hit higher weight sets after just a week of use.FEMALE USE (Testosterone): I did quite a bit of research on increased testosterone for women and it's possible negative side effects which range from not so serious (body hair growth) to MUCH more serious (hormonal and reproductive issues) which they mention as much on the label. Just from the mention on the label I would not recommend any women take it if they are attempting pregnancy in the near future, simply for precautionary reasons. As for myself, I have no plans to produce children nor plan to in my life (lesbian, but that's not why lol) so I have been okay overlooking this possible risk. I still get my period with the same frequency and have had no noticeable hormonal changes as far as hair growth or loss, (although I lucked out on genes and never grew facial hair or virtually any body hair to begin with). I would say my changes have been more physical, such as a broader back and shoulders as well as a stronger chest but it's hard to say whether it's from the testosterone use or the strength training as I do a lot of upper body strength training (or possibly a mix of both). Either way as a woman who is big into strength and body building, I recommend it's regular use, it's helped me out a ton. But I would advise you to do your research and consult yur OBGYN if you would like to take this and plan on also having a baby. Overtime I believe testosterone levels would wear down with stopping use.FLAVOR: I've tried blue raspberry and fruit punch so far and they both taste sweet, like one of those bodega juice jugs which I kind of like. Out of those two I like the blue raspberry a bit more because it's a little more tangy but that's just my preference. There is also no chalky feeling that I've felt with other pre's so they nailed it with the flavors so far.OVERALL: BUY IT, DRINK IT, GET BIG!

Great prework out good stim and pump
