If you're under 30, female, big tits, and this would be your 1st pharma job - take the $45K for 18 months and then bail out. You will do well...especially shacking up with your mgr and AD at POA's.
If you already work in pharma sales, stay away. It would be like playing 18 at Spyglass Hill and then playing 18 at the muni track in W Va.
