You mean the federal health professions loan? If you can't get a stafford loan, chances are you won't be able to get a health professions loan, since those are given to very few people, mostly low-income.
When I was applying for prepharm, only the most expensive school (Northeastern) gave me a health professions loan. I chose not to go there because it was far from home and USP seemed like it had a better reputation and was just a little bit cheaper.
