Loading... Please wait...Clinically Studied & Vasoactive Compounds!
GAT Nitraflex is a new breed of concentrated preworkout. And it is a very unique preworkout supplement because it has a testosterone enhancement compound called "Calcium fructopyranose borate (CFB)" to jack up free and total testosterone levels. The effects are clinically proven to work. CFB is completely non-steroidal, nature-identical compound. And the team at GAT did not add creatine to the formula in order to prevent undesirable water retention. If you are looking for the pump and the increase in muscle blood flow without taking creatine, Nitraflex is for you.
The Nitraflex pre-training 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 training, and provide long-term support of testosterone and nitric oxide levels in the healthy range when used as directed.
NITRAFLEX gives you so much hardcore intensity, full body pumps, and strength. You will need to try it out for yourself. GAT has infused new novel compounds of precise synergy, that within 3 hours of a single dose, it increased the the testosterone levels of healthy subjects by an average of over 10%. Over the course of 6 weeks of supplementation with this same compound, testosterone levels soared by nearly 60%.
How does "seething intensity" look and feel? Start taking NITRAFLEX today to find out. The size you get from tearing down flesh from within will be living proof.

This is now my favorite pre training supplement. My focus level goes up significantly without experiencing any crash for a relatively long time. Active8 kindly warned me about this, but the powder is clumpy. Not all, but it's rock hard, just to warn you. However it dissolves nice and quick when you mix the powder in cold water. 9/10 because of clump.

It's right up there with Jack3D. Possibly even better. You can't even compare it to the majority of pre-workout supp's because they make you all jittery and uncomfortable. The most expensive but the best.

From the third week and onward I gained a tolerance to the product and didnt have the same effect like the first two weeks, but what i really like about this product was that it still gave me energy to have a good workout.

This is one of the most intense pre-workouts I've tried. It tastes kinda bitter, but works great... and the best part is it doesn't make me all jittery like 1MR or razor8 blast powder
