The reason they help cut up is they require very little protein to work which helps the user diet down and not lose much to any muscle. EQ will harded the fuck out of you but will make you very hungry so you have to be careful to eat clean on it.
IMO, you can get cut from any A.S test, winnie etc.....its your diet and cardio and your workouts not the steroids, they definately help 99% but without a good diet and cardio its a waste...my $.02
All AS make dieting easier as you can get away with a greater caloric deficit without losing muscle. However there are definately steroids that have a more pronounced effect on fat burning. There is a study that states oxandrolone promotes greater fat loss in both subcutaneous and visceral fat stores in men. Especially lower abdominal fat. If this isn't a slap in the face to those that think some AS won't help burn fat I don't know what is. Numerous people have noticed fat loss using oxandrolone even while in a hypercaloric state, a phenomenon that is supposed to be impossible. My guess is that oxandrolone specifically causes the body to favor anabolism and then makes up for the energy deficit by breaking down fat stores.
