    • The dug will be daily for 6 months. Study Procedures. Every 2-4 weeks, the study participant will come in person for a research visit. Investigators will collect a blood sample at certain visits, do a brief physical exam, and obtain vital signs such as height, weight, blood pressure. The study also involves completing questionnaires, measuring body composition by a scan and testing muscle strength. The dose of JATENZO may be adjusted based on the testosterone levels.
