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

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

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.

Works well

Best pre work out, no jitterness and great performance

No es el mejor pero es bueno

I've tried A LOT of pre workouts, and nitraflex has been my go to since my first jug. This was my first time using the nitraflex+burn. It feels the same, great pump and sustained energy, awesome focus. I noticed I did not feel hungry right after my work out, possibly because of whatever is in this version that suppresses appetite. If you are cutting weight I recommend it.

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

My go-to pre-workout supplement an essential as part of my daily routine. I pair it with a nootropic to stay focused on my day to day running my businesses.

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