## Customer Reviews

### ⭐⭐⭐⭐⭐ Slick and quick
*by S***S on 29 October 2024*

Have tried many of these energy boosters and this particular one is by far the best. Works very quick without any groggy after effects or funny taste. Doesn’t over boost you either, so you’re not jittery and hyper; just smoothly elevated into the ‘ Zone ‘ if you know what I mean. Lasts for a few hours too. If you need a gentle pick me up when sluggish to give you that push to get to the gym then this is the one for you !

### ⭐⭐⭐⭐⭐ Wakey wakey
*by M***K on 13 May 2025*

Great flavour. Great little pick me up for work and early mornings.

### ⭐⭐⭐⭐ It works ok
*by M***. on 24 June 2024*

It makes me feel energised and I get more liquids in.I think it’s just the caffeine and some vitamins in action. I quite like the taste but it’s fairly artificial watermelon and the colour worries me a bit because it’s so bright.Not sure I would buy again but at the moment it’s handy as a quick pick me up. I like to use caffeine but not in the coffee form, so I already found one nootropic drink in powder I adored but they stop producing it so on the hunt for a replacement.The sachets are good, small to take with me and easy to use and the packaging is very oversized.Caffeine content: 32mg/100mlSweetener sucralose.I sometimes use only half of a sachet.Price was great that’s what attracted me. Maybe I would try a different flavour in the future.
