I hear contradicting oppinions all the time, people either saying "Take EQ to cut!" or "Take EQ when you have less than 12% BF!"

So what is better? If I'm already at 7% BF would I get much benifit from EQ (with Test)? I can never keep BF I'm a complete ecto, had to work my ass off for the 180 lean pounds I've got on me.
