NITRAFLEX Burn, Pre-Workout, Blue Raspberry, 30 Servings

Best pre work out, no jitterness and great performance

Awesome product been taking it for years now

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

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.

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.

Good product, I've been using it for a couple of years

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..
