I know two strongmen competitors that have used it, they took hefty doses in the start of a "regular" aas cycle and then continued with test, deca, dianabol/anadrol. Sorry i can't remember the dose they used. I'll ask if i run into either one.
PS. You need to know EVERYTHING possible if you choose to use it, it can have some serious sides. One spanish cyclist had a heart attack at 23, because of the blood clotting.
