Information Subjects Subjects can be male or female 18 years and older and in general good health. The studies have a variety of time commitments from one day a week for 2-4 weeks to 14 consecutive days.
Different studies have different requirements.
The majority of the studies require you live or have a place to stay in the Philadelphia metropolitan area. However, the long term studies do not have such requirements and are open to individuals of any geographic area, provided you can travel to Philadelphia as needed for the study. We have hostel information available. All potential subjects receive a thorough physical examination, laboratory screening and screening for drug usage. Once approved, they are placed into a pool of prospective research subjects.
