There is no way you're going to lose 10-15 pounds per week unless you start chopping off body parts. Approximately 2 lbs of body fat per week is a realistic goal. I'm cutting on a cycle of Test Prop, EQ and Anavar and I'm averaging 3.6 pounds of fat loss and 2.5 pounds of muslce gain every 2 weeks. That's with a strict diet and a lot of cardio.
EQ makes some people very hungry, so it may not be the best choice for cutting. If you're trying to make a weight class, I would suggest plenty of AM cardio and Anavar.
