there are actually a small amount of "stims"...so it's technically "caffeine free" ragnarok. The blend is a bit different but with the release of the new RagNOrok Ultra so near....things will be changing with both formulas. There WILL still be a caff free version though!
I can tell you that from my one time usage of the new RagNOrok Ultra, that the pump was pretty intense and the energy was very clean. I wasn't jittery at all and I did not have a "crash period" at all. There was also an intense feeling of "the tingles" from the very pure source of beta alanine in the new version.
I can also tell you that from my usage of Cre02/NitroCeps stack (only 3 days so far), that the 2 stack amazingly and that the pumps are also very very intense on NitroCeps. Cre-02 always has been one of my favorite products ever, and is even more intensified with the help of NitroCeps.
For energy i'd have to say that Ragnarok or RagNOrok Ultra with caffeine is clearly the choice. For focus and clarity...i'd have to say its really a 3 way tie. For Pumps i'd give the edge to the Cre-02/Nitroceps stack with the new RagNOrok also being intense. I can't even begin to tell you how many of these types of pre w/o products i've used in "my time"....and these 2 here simply blow them out of the water.
