Sexiyama isn't a lifetime natural but it's easy to believe that he's relatively clean.
I know guys like him and they don't like to juice all the time. They only use it to get the job done and get whatever athletic benefits they can. They believe in cycling AAS, low dosed GH, try to stay clean for a longer period of time and don't believe their is an advantage to staying on all the time. I would probably follow the same drug regimen. These guys abhor dysfunctional, useless, oxygen-sapping muscle and they're correct.
