can't on NaNo but i did go from superpump250 to amp and it is different. on superpump i would go into the gym shaking like a crack head and amp gives me a calm powerful feeling.
I liked Nano, but definately like amp better. I have all the energy and focus I had on nano plus keep the killer sweat going. Difference is I would feel like crap 1 1/2 or 2 hour after nano, and don't have that problem with Amp. Also easier on my stomach!
i wouldn't do 6 caps to start off then. start at 3-4 and work your way up. if you start at 6 you will feel/look like a crack head in the gym being that sensative, LOL.
