They are truly different compounds, bro. Superdrol is the "stronger" of the two drugs and shines when u want to do a dry bulk because it does not produce the water retention u get from Anadrol. A four week Superdrol run should give u fullness and vascularity. Anadrol, still is the reference standard for driving water into the muslce fiber at a low BF giving u a massive almost contest ready appearance. So, bro, I think your choice of anadrol is the right one for your purposes. I don't know anyone that uses Superdrol up to the day of a show to "re-hydrate" the muscle tissue but we use Anadrol and dbol.
