Pre-exposure Prophylaxis (PrEP) Adherence for Black MSM

The goal of this clinical trial is to learn if two interventions-C4 and C4+3MV-can improve PrEP adherence (taking medication to prevent HIV) among Black men who have sex with men (MSM). The study will also explore the most effective ways to support participants in continuing their PrEP use over time. The main questions it aims to answer are: * Does the C4 program help participants take PrEP more regularly? * Does adding the 3MV intervention to C4 provide additional support for adherence? Researchers will compare two intervention strategies to see if they result in better PrEP adherence: * C4 Intervention: A program focused on individualized care coordination and addressing structural needs. * C4 + 3MV Intervention: A combination of care coordination with additional behavioral change sessions. Participants will: * Participate in PrEP education and counseling sessions. * Have their PrEP use monitored through dried blood spot (DBS) tests. * Complete questionnaires about their experiences and challenges with PrEP. Receive support sessions tailored to address individual barriers to PrEP adherence.
