Rated 5 out of 5 by from Just right I've used a few different pre workouts and while this isn't the most explosive it does what you want. Quite simply I feel at my best after taking this with virtually zero side effects, a little gassy is all. Friends have suggested I could increase the dose, and while this might give a bigger boost I don't think it's necessary. It was reduced when bought, and while it is good I would never buy it at full price, just not justified by results. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Awesome pre workout I bought this a few weeks ago as I had ran out of my regular pre workout! I've tried the lemon flavour grenade before which didn't taste that great but this berry blast was so much better! My workouts were very focused and I got that tingly feeling! As a bonus the delivery was super quick I ordered it on standard delivery and It came the next day! [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Doesn’t work for me Obviously everybody is different and this will effect everyone different, but I found it was a poor pre workout.. it tastes disgusting and turns carbonated when mixed which I find hard to drink right before a workout, it also just made me feel really bloated and had not explosive effects at all, I could of literally gone to sleep after using 2 scoops. I preferred the optomimum nutrition pre workout as I found the effects of that actually worked, each to their own though..

Rated 2 out of 5 by from Poor I've only tried 1 pre workout before but this one is about 5 times less efective. Besides, it made my sleep very bad .

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.
