no one can make that decision for you. I assume you go to a 1-6 year school?
anyways...what are you interested in doing? do you want to interact with patients/doctors/etc? then you should try and get back into pharmacy.
If that is not possible or you want to work more in a lab? try pharm/tox or pharm/sci or maybe pharmacy administration?
if it is about what can transfer over more with regards to pharmacy credits...check with the school..i know at USP...pharm/tox and pharmacy are pretty similiar until 4th year.
