the one that converts str8 into estrogen. nothing anabolic/androgenic is going to not raise cholesterol. its a side effect. you can take support supplements to help keep it from shooting through the roof. but it is still going to go up.
best best is to take cholesterol lowering supps before a cycle, while eating a healthy diet high in fiber, and exercising on a regular basis. get you chol. as good as you can before you shred it to peices with a pro hormone.
