Great
I'm a fan of Nitraflex. When I first started taking their powders I wasn't quite understanding how the results would come into play with my work-outs. More hoping for a power boost and miracles.Now being more experienced going back to Nitraflex.. I value what I'm getting out of their products.Nitraflex is no joke to caffeine / energy boost and other effects to give your body a boost when working out.It's a product including their other powders I would view as top of the line.Jeremiah Project Fabulosity

Terrible
This is my first review I?ve ever written about a product it?s that bad. I?ve been working out since 2012 regularly and I?ve tried a lot of preworkouts starting with Walmart brands and up. This is probably the worst preworkout performance wise I?ve had in a long time. Does nothing for me.

Glass in preworkout?????
I found glass in my pre workout. I contacted GAT and vitamin shoppe neither of which cared. Vitamin shop corporate number claimed to be sending me a replacement at the beginning of January, its now March and I have yet to receive anything. Needless to say I will not be shopping here again or purchasing anymore GAT products.

Bring back lemon-lime.
Very disappointed Nitraflex+C discontinued its lemon-lime flavor. It was by far the best flavor they ever had. I was sent samples of many new flavors and they are all vastly inferior to lemon-lime. Fruit punch is the least bad.

About
Nitraflex
A shopper

  I asked this same question to a Vitamin Shoppe Associate over a year ago. If I remember correctly there isn't much caffeine. The extra energy comes from ashwanga which helps to balance the chemicals in the body and the enhanced testosterone. My son started taking this product and he became so full of energy, confident and outgoing that I thought he may be on drugs. This is why I visited the vitamin shoppe to question the product and was very happy with the information.
