Currently im running cutting running a stack of DCP/HEAT/Eviserate and erase.
My body fat is around about 13-15% and im 203 pounds and I was wondering which would be better to us to in order to lean out my lower/side abs and lower back, eviserate or abliderate?
In my opinion it depends. You could use eviscerate with much success. If you are closer to 15% body fat I would recommend getting a little leaner first. If you are closer to 13% you should be good. It really depends on body type.
Eviscerate WILL be helpful either way, BUT you could loose another couple BF% with diet alone and then use Eviscerate. I feel you will get more bang for your buck with Eviscerate if you are already fairly lean (I am not implying your not). The D/H/E is very effective for fat burning, But the effects from Eviscerate become much more noticeable as you get leaner and leaner.
But to directly answer the question you asked Eviscerate will absolutely help you lean out your lower/ side abs and lower back.
