I had crazy painful muscle pumps with anadrol. I was much stronger, but it was pointless strength as I could barely move halfway into my workout. I'd literally have to stop walking and stand in place for a few minutes until the pumps went away. It would only happen on leg days. Mainly in my lower back and somewhat in my quads.

I'm off it now (was frontloading), and my workouts are much better.

Personally, I'll stick with dbol.
