absolutely no money in it (other than the top few).
think about the NY Pro. If you finished in 6th place, which is somewhat respectable, you got ZERO prize money. The supplements alone for that show probably cost 5-10 grand. Finishing 6th or 7th, you probably do not have a good sponsor, so no money there either. even 4th place (toney freeman?) only got 3 grand (or close to 2 grand after taxes).
I know a lot will say G4P, but seriously, why would you compete and be a pro? I would imagine the vast majority who do, actually LOSE money doing so.
