No idea what he was/is running. If anything at all, which I don't suspect.
There was this one black dude in a neighboring high school when I was a senior. He was a junior and dude had legit 18.5" arms. Weighed 215 and had a 30" waist. Ripped and vascular beyond anything you could imagine. He was completely natural. Was a training and cardio freak. His school didn't have a weight room and the coach at our school would let him come over after school and use the gym there. And I know he was natural because this dude didn't have a pot to piss in. He would walk 7-8 miles home from our school every day if he didn't have a ride from someone there. I gave him a ride quite a few times and his house was a complete shit hole with no grass at all in the front or back. All dirt. His parents couldn't even afford to him money for snacks (soda and chips) at school so the only decent meal he had all day was the food they served in the cafeteria. He told me once that he would pay 10 cents for an extra milk and have 3-4 friends to the same and all give him the extras so he could drink one serving of milk between classes. I can only imagine what this dude could have accomplished on just an ample supply of clean food alone. Add in AAS he would have been a pro no doubt. Sadly, he was killed a year after he graduated high school. But honest to God he probably had the best genetics of anyone on this planet next to Ronnie Coleman.
