who likes superpump 250 or who does'nt? I have used NO2 from mri I liked it but my butt hurt from the cost rape I took when I bought it. Amplify o2 was way better and half the price I liked it alot. but I heard superpump 250 was awesome too but also heard that it should be called superdump 250 cuz you shit your guts out on it. I can pick up a container of it for 35 bucks so I thought I would give it a try. just wondering what others think of it.
