Once a week. If you're going to shoot EOD, why not just use prop? That's why there are different esters. Why make it harder than it is?? This question always pops up. If you're going to shoot cyp and ent so often would you also shoot EQ and Deca the same? No. People always want to shoot test often, but when it comes to EQ and Deca, it's always once a week.
