Bear - what did you notice from superpump 250??
noticed several things, including super pumps (ha, ha....nothing? not even a titter?) And improved gains in spite of a reasonably low-carb and low-calorie intake (2500 cals, 250 g carbs). I noticed it most on leg days, where i was able to have 90-minute workouts of insane intensity.
I maintain, however, that it is not worth the 60 bucks i paid for it every three weeks.
If you want roid-results, buy roids. Otherwise, i'm all for the inexpensive but tried-and-true supps.
