At 600mgs a week a lot of extra side effects will most likely happen. Some people could probably cruise on 600mgs a week and not have side effects but most people would see negative effects eventually. Me personally I would experience hair loss, high estrogen, high hematocrit levels, high blood pressure, and worse lipids. A lot of the guys on here are vets and seem to not get many negative side effects so I expect most of you just tolerate steroids very well.
