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

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!

I used to use this brand all the time, but out of curiosity, I started using others, just to see what they were like. Now I'm back on Nitraflex, and I can see the difference is clear. I've never felt better in or out of the gym than when I'm using this stuff. It works great, I feel great. I'm super locked in, and I keep feeling great afterwards. Definitely recommend for advanced fitness enthusiasts.

Awesome product. Works well. Taste is amazing. I like how it includes the moisture packets inside to prevent lumping.

It's my favorite

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.

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.

Good stuff at a great price

Great pre workout

This is my go to pre-workout. Good pump

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

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.

Not sure if the formula has changed recently but, feels like it’s filled with beta alanine, almost to much. Very little stimulation and no pump. Taste is ok, Wouldn’t recommend for pre workout.
