Key Ingredients

This is the most scientifically advanced Nitraflex formula to date! Nitraflex now includes patented Nitrosigine®; Shown through clinical research to help boost energy, increase blood flow, enhance muscle volume and the pump, improve mental focus, and combat muscle damage from intense bouts of exercise.* Next, a higher dose of L-Citrulline was used in Nitraflex to aid in increasing nitric oxide (NO) levels to enhance the pump while also helping improve blood flow into the working muscles to transport oxygenated blood and key nutrients.* Unlike some pre-workouts, the Beta-Alanine in Nitraflex was not “fairy dusted” in this formula. Rather, a significant dose was added that you can feel working following your very first serving. You can now increase your natural testosterone levels and help add the quality lean muscle mass you demand through the inclusion of more elemental boron per scoop than ever before.* Lastly, you requested it, we listened! Per your wishes, all artificial colors and dyes have been removed from Nitraflex!

Please replace this “new formula”, I received this product as a gift and it is not the same at all.

I had been using Nitraflex for 4+ years and loved it, but the new formula is bad. Almost undrinkable flavor, and I regrettably got a couple different ones and they’re all that way. Less effective too. Definitely a step in the wrong direction. As long as this is what they’re selling, I won’t be buying.

I have been using NitraFlex for over 7 years and have ALWAYS gotten the Fruit Punch. I have to say this new formula is HORRIBLE. It tastes completely different and in the worst ways. This tastes like a cheap start-up supplement company that you would find in CVS. Highly, highly disappointed. I would consider this product a 9-10 before the formula change, sad to see this company make a major mistake like this.

So as per usual with the “new formula!!!” I knew it was gonna be worse. I was right, compared the ingredients to my old tub... a lot is cut out for some other garbage. It feels like one of those cheap preworkouts. Instead of a clean energy and pump it’s replaced with those cheapo tingles. I have been using nitraflex for almost 3 years, and no more. Stay away until this cheap garbage gets fixed. I will now be looking for a new pre workout. This was gifted to me at my request, but I regret it. Feel free to try for yourself, but man just pure disappointment.
