GAT Sport Nitraflex®

German American Technologies has taken Nitric Oxide, Vasodilating Preworkouts to the next level by adding powerful Testosterone enhancers to provide the strongest pumps and hormonal support in Nitraflex.

Hyperemia & Testosterone Enhancing PWD (Clinically-Studied CFB & Vasoactive Compounds). Highest Concentration (More than 3x Strength): 1-Scoop Potency. Reactive hyperemia describes the increase in muscle blood flow that occurs during high-intensity resistance exercise and produces the "pump" associated with increases in muscle size. The Nitraflex pretraining formula contains ingredients that in vitro, animal and clinical studies suggest possess properties that may help advanced athletes maximize energy, intensity, vascularity and reactive hyperemia (pumps) during their workouts, and provide long-term support of testosterone and nitric oxide levels in the healthy range when used as directed.

Unique Properties of some of the key compounds in Nitraflex: 1-Scoop Potency: Nitraflex is so potent, only 1 scoop (1 serving) is necessary. Do not exceed 1 scoop in a single 24-hour period. Do not take Nitraflex with 5 hours of bedtime. High Citrulline: Arginine Ratio: Arginine is a proven precursor in nitric oxide (NO), a vasodialator. What most people don?t know is that Arginine supplementation stimulates the activity of arginase, an enzyme that breaks down Arginine. Over time, this may actually result in reduced Arginine and NO levels in turn causing your preworkout formula to stop working. Research suggests that supplementing with a high ration of citrulline to Arginine may reduce this risk by avoiding overstimulation of arginase.

6 Weeks of Testosterone: Calcium fructopyranose borate (CFB) has been shown to increase testosterone in health subjects. The average increase in total and free testosterone in a 6-week study was 56% and 29.5% respectively. In a second study, total and free testosterone increased on 3 hours after a single dose of CFB. Effective Doses of Beta-Alanine: The clinically-proven performance enhancer beta-alanine was not ?fairy dusted? in this formula. Rather, we added an exceptionally powerful does that you will feel working following your very first serving. Creatine-Free: Creatine causes water retention, which can make achieving a dry, hard muscular look even more difficult. Sometimes creatine is added to products precisely for this reason. (When you see yourself getting bloated, you may be fooled into thinking the product is ?working.?) We left it out of Nitraflex precisely for this reason. Cognitive Enhancers: Nitraflex contains unique ratios of scientifically validated compounds that help you remain alert, intense and focused while you?re flying from set to set with veins fully dialated and muscles pumped to the hilt.

  • Creatine Free
  • Powerful Energy: Contains 325mg Caffeine

Above average
I've been taking nitraflex for about a week now! As far as a pump comes, this product gives you that! Energy wise, not so well... By the end of my workout I'm just about ready to pass out everytime. Have not noticed an increased amout of testosterone if that's really why you want this product. Overall, I would recommend GAT Nitraflex

Highly recommended
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.

This is the best pre I have ever taken!
I waited for months to receive my recent order of supplements from Tiger Fitness simply because I'm a deployed Marine with the 22nd MEU! I got my package just recently and I immediately wanted to try out my new sups, GAT Nitraflex and GAT Adenoflex is what I ordered, along with MTS Machine Whey, PB Fluff. I took the recommended dosage for the first time and almost sprinted to the gym to hit the bench and get a super pump! Needless to say, I got the best pump of my life and pushed through every level of fatigue I encountered! I would highly recommend GAT for anyone who hits a plateau and wants to bust through it! Thanks for selling great products and for awesome customer service!

The pump was phenomenal, and
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.

Well what can I say,
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
