I've just had a super fast read through and just want to make a quick point . . . The steroids are the icing. You need to make the cake first. There is no magic point. It's an ongoing week in week out year in year out regime. Changing routines and even taking a week off is all part of that regime. Steroids will just help you recover from lifting heavier and harder and it will still take time to get to heavier and harder.
