gat nitraflex green apple

GAT Nitraflex is not only a potent pre-workout but a muscle-volumising and testosterone-boosting powder. This makes it much more than your average pre-workout.


Not only do you get the energy and focus expected from a quality pre-workout, but also increased blood flow to muscle tissue. This ensures all the nutrients are delivered at a rapid rate to your muscle for an uprecedented workout.


This GAT pre-workout contains a number of nitric-oxide boosting ingredients, including Citrulline, Citrulline Malate, L-Arginine Malate and L-Arginine AKG. Arginine serves as a basic building block for nitric oxide 1. Citrulline itself is believed to be even more powerful than Arginine 2 !


One study showed that Citrulline Malate alone can boost bench press volume and reduce delayed onset muscle soreness 3. More volume, less pain ... not a bad trade off at all!


  • Muscle Volumiser
  • Boost Energy
  • Buffer Lactate
  • Enhance Testosterone Levels


Nitraflex from GAT Sport produce contains ingredients to specifically support testosterone. And with enhanced testosterone comes improved training motivation and intensity, faster recovery and enhanced muscle growth. Nitraflex contains a key ingredient called calcium fructopyranese borate shown to boost testosterone levels within 3 hours of a single dose. And that's free testosterone too, not just total. Boron is one of the few natural free testosterone boosters that has been proven to work in young, healthy men 4


This pre-workout was tested in a double blind pilot study using subjects with 3-5 years experience in resistance training. GAT Nitraflex was shown to increase strength, stamina and testosterone levels after just 2 weeks at a 1 scoop serving. All subjects increased their bench press weights by 2.3 - 5.5kg and all subjects increase their muscle work capacity. 


Nitraflex was not only designed to improve your workout performance amd intensity, it has actually been proven.
