    LOVE THESE DRINKS! Faves are definitely strawberry, grape, watermelon and apple. But the others aren’t bad either! A mix pack is the way to go if you can’t decide which flavour to go with.

    10/10 Mix It Up

    LOVE all the flavors.. couldn’t narrow it down to one fave so it’s fantastic that sprint fit sells a mixed pack! If you’re looking for a sugar free electrolyte energy drink then look no further! These taste great and give you that pre workout buzz or afternoon pick me up!

    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.

    10/10 Mango Pineapple Limeade

    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

    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
  • 4/5
    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.
