i would say less than you think. if they get there gh for 100bucks a kit (and some probably don't pay at all) thats a kit every 5 days @30ius a day
6k=gh
2k=test 25 bucks a bottle 2 bottles a wk
2k=tren,eq
500 bucks=insulina
1k=misc. drugs,peptides or SEO
food could be high 200bucks a week still under 10k
so IMO a pro would spend no more than 22k a year on everything
