I think it depends on your goals. But at a certain point either way some times you have to raise the dosage. The key is to use the least possible amount of steroids with the most emphasis on nutrition and supplements and proper training for your gains. Steroids might build more muscle the higher you dose them but that doesn't mean that your going to be able to tolerate the side effects the increase in dosage will cause. A lot of times instead of increasing the dosage some one would be way better off just changing up their diet and training.
