You may have something in only staying on for 1 week, but 1 week off probably would not be enough to restore natural test levels. My guess would be the next 1-weeker would only yield the same gain you woulda got from a continous 2nd week. Maybe 1 week on/ 2off would be effective & definitely minimize sides.
It may be worth a try though. I'd like to hear results if you do.
