Grenade .50 Calibre Pre-Workout Berry Blast is rated 3.2 out of 5 by 6.
Rated 5 out of 5 by from Bombs away! I for a long time needed some sort of boost of energy finishing late at work and going straight to the gym after to do a late weight session i was drained but still pushed myself to get in the gym. I then thought i cant carry on like this feeling totally drained and fatigued my workouts were suffering i would finish up and go home annoyed that i cant give my best because of being totally drained. With Grenade 50 calibre it has given me an unbelievable difference once taking this you will feel an energy that will give your weight lifting workouts a massive boost. I break my pb after pb on each exercise easily when using this. defo 5 stars from me.

Rated 3 out of 5 by from Better than nothing! Well ive had pre-workouts before and this isnt the best. It has poor mixability and tastes poor but i did have a strong intense workout, i had the larger dose mind.

Rated 1 out of 5 by from does what it says on the tin! Tried the free sachet that came with the grenade pills, its like drinking 10 cans of redbull, the rush hits you straight away, and is very over powering energy rush! do not take after lunch as you wont be sleeping at night! gave me a headache and couldnt sleep wont be using again
