    Good get up before workout, great taste and gives you the boost you need

    10/10 Blueberry Lemonade

    The first time using this preworkout I definitely found an increase in endurance and energy. However lately I've been finding that it hasn't really kicked in as much as what I'd like it to (find myself yawning in the gym). Not sure on whether to increase the amount on how much I use but taste is great!

    10/10 Watermelon

    Never taken pre workout before, but this got me in the zone ready to smash out a heavy session. It goes down well and at the moment watermelon is my favorite flavor

    I only have half a scoop as I don't have caffeine otherwise. It definitely does the trick and tastes really nice as well! Green apple hits different.

    Second time ever trying a pre workout. First time was some crazy one which gave my body crazy pins and needles which apparently was normal but just drove me crazy and I'd been put off ever since. This pre workout both tastes good and gives you plenty of energy for a workout (even a long, heavy leg day) without feeling like you have fire ants under your skin. Would recommend to others and this will be my go to from now on.
