I know that people have taken a lot of shots at this poor guy but I will try to give a helpful answer. Since they are both orals that can cause severe damage to the liver if taken in high doses or over long periods of time. By combining the two they will cause much more damage than when taken alone. Your liver is one of the few organs that can regenerate but only to a certain point. So the short answer would be yes you could take them together for muscle mass but I think the bloat from the dbol may take away from the leaning properties of winny. The downside from a two oral cycle could be severe liver damage.
