This isn't a thread about whether of not fighters should be allowed to take testosterone. Just fighters who are legally known and permitted to because of existing low levels. I can think of three examples - Dan Henderson, Todd Duffee and Chael Sonnen. I was wondering if Brock had a history seeing he spent so long in WWE where steroid abuse was rife. I'm not bashing anyone, i love these fighters (no homo) - just curious.
