I bought the z01, z02 and z04.
They all taste better than the Japanese ones and I think they work well with caffeine.
I think the package was a long way to Japan, but the shipping was fast and I was relieved.
Also, the item I received was well packed.

Z FUEL Pink Punch

Tasty and fruity flavour. Ideal when you're a bit sleepy in the afternoon to get an extra boost.

Brać póki jest na stocku

Not being a punch kinda girl was a little skeptical on this one but it really changed my mind the flavour that you get is just awesome and with the added caffeine just kicking these into high gear really recommend this
