This is the original formula for C4 Ultimate. Better than the latest ver. 2.*

I have tried several pre-workouts, and I had one as my favorite, it was not until I tried this C4 Ultimate, it has given me the best performance while I train and the flavor is very good, I recommend it.*

New formula, so do check it to make sure its still got what you want.
The ingredients still pretty much match what the science is saying should work and in the right amounts. They've removed some things that it didn't really need and added different chemical forms of some stuff (that may be more bioavailable etc).
For me it's still great and works a charm. I add a bit of extra creatine, some inulin and tyrosine as I've found then useful.
I've had great success and sustainability using these (though I do take a break from it every 7th week) and I find the cost not too prohibitive, knowing that it does work.
All I can suggest is you give it a try and see if it works for you, too.*

Are my ears burning? Man, this stuff is the absolute bomb! The flavors are solid but the effect is what I bought it for.
I recommend it for anybody looking for a pre-workout with an edge.*
