I have -- ONLY workout days (EOD) at 10-40mg. Works very well for that extra kick. I had the same results as taking it ED at 20-30mg.
However, the lower back pumps got in the way of training even at 10mg EOD. As a result, I had to stop short more than a few times workouts and dbol regimen. Nevertheless, very good oral if you can tolerate the pumps.
