My son shared a sample with me and I am hooked.This is a great product.

Really sour tasting shot that sure gets your face tingling, after having it first thing in the morning it didn't half wake me up after nearly blowing my socks off, will definitely be getting some of these super convenient shots again!

I really like the flavour of these shots I love a sour flavour and these have a proper spur kick.. yum.. I think the source zing also helps kick start the energy. I've used these a few times on long lat work shifts when I start getting tired really does help give me my second wind.

C4 Energy Shot - 60ml x 12 pack. The energy shots arrive in the manufacturers box and contain 12 single servings of C4 energy in 60ml one shot bottles and each serving has 150mg caffeine. I am a member of a popular social media forum beginning with R which has it's own sub section for "energy drinks" I have read numerous posts over the last year about C4 energy and how it marks 10/10 for taste and effectiveness for a boost, this is for the energy drink cans though. I am yet to find this C4 energy in UK brick stores though despite looking for it, I know it is online in bulk but i may not like it so I would just want to purchase one to begin with. The taste of these drinks is a sour and tart and rather pleasant. To be able to try the C4 shot in UK is brilliant.

Now these are definitely a marmite sort of flavour, you'll either love them or you'll hate them. Personally I love a sour flavour so these were ideal for me although I also gave a bottle to a friend of mine and they felt it was too sour. Aside from taste, myself and my friend both felt a noticeable difference in energy from these shots. Price is reasonable and I think they're ideal for most.
