Gat is an awesome product great pump no jitters would highly recommend it. Will definitely buy it from tiger fitness they sent it when they said they would and I got a tracking number with it so I could keep up with it.
I had previously tried a sample of Nitraflex and enjoyed it, so I pulled the trigger on a full tub. It was an excellent choice! Great quality of ingredients and flavor was adequate. My workouts are consistently supercharged without the crazy crash or jitters that come with other heavier stem pre’s. Ordering was simple and my product arrived in just a few days. Will be ordering again!
I’ve tried a lot of pre workouts and usually they don’t give me the pump and energy that I need, but this formula gives just what I need and doesn’t make me stay up too late(I usually work out in the evenings)
This pre workout delivers big time. Not only does it deliver on energy but it also gives me incredible pumps and tastes very well to boot. Top notch supplement from a very consistent brand.
Hands down, my favorite preworkout! & the pina collada is crazy! If you like bang pina collada, you’ll love this. I tried nitraflex first from a bag full of preworkout samples from the Olympia expo. No crash, no jitters at all even on an empty stomach. Doesn’t give me the runs like a lot of other pre’s. I’ll definitely be ordering nitraflex again and again.
This is my second container of Nitraflex and this was even better than the first! The pump you get from this product is unreal, it feels like my muscles are going to explode. Highly recommend to anyone who is interested in getting swole
It gives you good clean long burning energy for an explosive workout with out the yucky pump or "focus" feeling. Great for any training. I use it for endurance cardio. The flavors are great too, though i use each serving with 16 oz of water.
The best of the best as always! Energy and pump always on point! Just don't take too much or you won't be sleeping for at least 24 hours. Still my favorite out there. Pina Colada is the worst flavor, in my opinion, but still not bad.
Wow. Get ready to get pumped and get burning. This Nitraflex is so effective and so immediate that you can feel the tingling as soon as you drink it. Loaded with Beta-a and nitrogen boosting ingredients you will be sure to have bulging veins and one intense workout.
I enjoy using the Nitraflex, the blue raspberry flavor is my favorite. I feel energized and feel like I can get that extra rep more than with other preworkouts. The timing and customer service of tiger fitness is the only way to go
The pump was phenomenal, and I'm very tolerant on caffeine but I was goose and pumped from this preworkout, I've almost every popular pre workout and this is by far in my top 2. I will definitely purchase this again.
Love this preworkout. Get energy even for me with a high tolerance to caffeine. The test booster is great also, from the first use I could tell the difference. Only pre ill buy from now on.
Well what can I say, I've tried a lot of pre workout. A lot. Nitraflex is my absolute favorite, great pump, huge mg dosage of caffeine to give me drive for each and every workout. Best flavor to me is blue Raz. 2nd is probably fruit punch. If you haven't tried it yet, you should. Not for the faint of heart, if you're looking for laser focus and a great workout, this is for you
