Kimo
Baroni
Leben
Ken Shamrock

All caught with Stanozolol in their system at some point in their careers. Which btw, is rarely used for building muscle, but instead retaining it during the cutting cycle.
That's not even mentioning the others who were caught for non-FDA approved steroids.

Barnett - (Boldenone, Nandrolone, and Fluoxymesterone)
Bonnar - (TWICE, 11/3/06 - Boldenone, 11/2/12 - Drostanolone)
Sherk - (Nandrolone)
Hermes - (Drostanolone)

James Irvin - (Epitrenbolone)
Mo Lawal - (Drostanalone)

I'm guessing because there is allegedly a vagina between her legs? 
Alves got caught with the same thing. All it does is help you shed weight while maintaining your muscle mass.
Handsome Jack - I'm guessing because there is allegedly a vagina between her legs?Correct!
She may not be the only one but she seems to be someone who benefitted greatly and seemed to be unnaturally strong and fast for a women. She fought like a man.
