  • 10/10 Watermelon

    Love these drinks. My favourite's were Strawberry & the watermelon. Really refreshing after a long run. I've taken them out a few times over Xmas when other people are drinking alcohol so I feel like I have a drink in hand aswell. A nice treat 2 have in the fridge.

    Seriously my absolute favorite ! I love these so much. Not too high in caffeine and zero sugar! How in the world do they get these to taste so freaking good when they don't use sugar!? They're easy to drink and such a perfect size. I use them as a pick me up while I'm on the go or running late for the gym and didn't have time to make myself an amino BCAA drink
  • 8/10 Watermelon

    10/10 Grape

    Absolutely love these drinks. Great substitute for if you are addicted to energy drinks. I have one every morning if I have a workout or if I just need a boost
  • Sooo yummy and convenient. I've found they don't even need to be refrigerated which is ideal to just pop in your gym bag and go. Delivers such a good amino hit as well as an extra punch of energy! I feel like most of the flavours are stellar, except the Mango Pineapple Limeade reminded me of a Passionfruit Cruiser hahaha... might be down to personal preference as mango wouldn't normally be my go-to! The strawberry and watermelon are yuuuuuum and super summery.
  • 10/10 Mix It Up
