what is Rupinal??

 Just watched a video on sherdog, about Paulo Filho and he said he had been using this for 8 years. When I looked it up I couldn't find out much about it, but it did bring up something about vets and cats and dogs, but i'm trying to figure out what it does....is it a steroid, muscle relaxer, or....????

 god damn, that must be one crazy s.o.b to date rape himself...which brings the question is it date rape if he slipped it to himself....
