I don't know what he takes but knowing how things are here and knowing that he doesn't exactly come from money, I'd say it's mostly basic stacks. Pharma test, deca and EQ are easy to find here. Brazilians do like their winny. Masteron isn't huge. HGH only in small doses and close to competition, since it's way too expensive. He talks a lot about manipulating food and seems to spend hours on posing. Of course, he's gifted, very talented and goal oriented.
Kid has a bright future in bodybuilding, I think. I'd try to spend some time in Kuwait if I was him.
