The 7 days I ran both, 30mgs beast a day. 250 mgs katana a day.
I went from 180 to 185 and lost body fat. Strength exploded. My over head tricep presses went from 3 sets of 12 with a 100 lbs dumb bell to the same thing with the 120 lbs dumb bell.
Every muscle got hard and more developed looking. If I can stand the flu like symptoms of the beast it would be awesome.
I ran both and loved it. try beast at 20mg and katana.. as high as you can afford and it is a great cycle with very manageable sides.. dont skimp on the supps and pct
