Bio-Gro brand iSatori is of course here at this weekend’s Arnold Sports Festival with a booth covered in red and black. It has all of its latest innovations on display with the likes of Bio-Active Whey as well as its older products like our top rated pre-workout Pre-Gro. The supplements are also all available with some great show specials. The one thing missing however that we were kind of hoping to see is Pre-Gro Max. We haven’t actually heard or seen the sequel pre-workout since we got our first look at it two weeks back, so for now it is still just coming soon.
