Review by John hemmings on Aug 25, 2022
Great taste and good price. I started drinking this product because the gym stocked it. Its great that i can buy direct to before BJJ, great seller and product 👌

Great pick me up during/ after a workout

Review by LM on Jun 2, 2022
I usually hate ‘energy’ drinks - full of sugar and tasting very artificial. These are great. I like all the flavours. I just wish it was possible to buy a 24 pack of mixed flavours rather than just of one flavour.

Great flavour and prompt delivery

Review by Abi on May 30, 2022
We got the tropical flavour and they are so delicious! We tend to have them in your pre-workout meal to fuel the session, or even as a pick-me-up.

Excellent energy drink

Review by Jane Hiser on Aug 1, 2021
Love the tropical flavour energy drink. It is a bonus that it is low sugar too.
