Do they compare to the original Craze?

In most people's experience? No.
I didn't even like the OG personally.
He who transforms himself into a beast, frees himself from the pain of being a man.

I only took one tub worth of the OG Craze. Definitely had better pre workouts.
To answer your question, most the reviews I've seen didn't like the new Craze.
New formula does seem to have a little less kick, but still my go to pre. Stacked with hamavol is awesome! I've tried many other pre workouts and always come back to craze.
