NITRAFLEX Burn, Blue Raspberry, 7.23 oz (30 Servings) | Thermogenic Pre-Workout Energy Supplement Drink Mix with Nitrosigine & Caffeine Anhydrous*

Best pre work out, no jitterness and great performance

I have been using Nitraflex for a couple of years on and off. This is the first time I’ve tried the Burn product. On the first time I used the product I found it to be very good. It does have a spicy taste but not terrible and the pump was strong. I recommend the Nitraflex products just be aware the caffeine level is high so start slow and work up to the amount your body can handle.

I’ve been weight training for 27 years and have used GAT for many of them. I’ve been using the burn for roughly 2 years and swear by its results. I take it then immediately start my warmups, it kicks in quickly. It will get you through a brutal workout, and it lives up to its name.

Works well

No es el mejor pero es bueno

This is so good and it makes you sweat so much more!

Awesome product been taking it for years now

Pretty Spicy but worth the pain after chugging- goes away in a few minutes

It didn't meet my expectations, no noticeable power or sweat in the Gym, just kept me awake at night cause of the caffeine..
