Confused on anbiolics filtered by the kidneys

[pappaprime]

I will keep it simple. Is Dianablol or Var filtered out by the kidneys? I thought orals were hard on the liver but cannot find hard evidence they don't hurt the kidneys.

What about NPP? Same as above.
And just to be clear I am aware of any anabolic that raises blood pressure has the ability to indirectly cause kidney damage. This is assuming BP is kept under control.
Thanks in advance.
