Review: Nice energy boost - I drink a fair amount of C4 before workouts because I love the beta-alanine tingle, and it always wakes me up without a massive crash later. I usually stick to the Frozen Bombsicle or Skittles flavors, but I decided to give Cosmic Rainbow a shot for a change of pace. It is definitely still very tasty—it’s sweet and fruity, kind of like a handful of melted candy. However, it’s just not quite as nice as the other options they have. It feels a little generic compared to their branded collabs. I’d happily drink it again if it was the only cold one in the fridge, but it probably won't be my first choice next time.
Review: Tastes like a handful of skittles - Best tasting energy drink- and this is coming from someone that drinks loads of energy drinks of all different brands. The flavour is sweet (but sugar free) and really does taste like a handful of skittles. Especially tasty when cold, although some may find it too sweet. C4 energy drinks also seem to give me lots more energy than alternative energy drinks of the same size, which is great before gym or simply for an energy boost.

## Questions & Answers

**Q: Is Cosmic Rainbow the same as US Skittles flavour?**
A: No idea but it didn't taste like skittles to me.
It is delicious though and doesn't get sickly either. It most probably tastes better than a skittles drink.

### ⭐⭐⭐⭐ Value for money
*by L***4 on 23 November 2023*

I chose to buy these drinks for better value as they sell them at my gym for a jumper up price! I wasn’t disappointed- although this particular flavour wasn’t my favourite- I prefer the pineapple and would definitely purchase that next time. All I would say (although this could have occurred in transit as the box it arrived in was quite large around it) is that several of the cans were dented and damaged - not to the point of being un drinkable fortunately- but I do know that can dents and damage may effect the product inside. I was lucky this wasn’t the case - I think in Hindsight I should have contacted the seller for replacements. As I said though great value for money and decent energy workout drink! Would purchase again!
