This observational study is designed to determine the feasibility of recruitment from a digital research community of people using an anti-obesity medication for weight loss to understand willingness to consent to survey research and at home self-blood testing. This study will engage an active community of people using anti-obesity medications, semaglutide and tirzepatide, indicated for weight loss to examine the willingness of participants to engage in a digital study, provide consent, and complete various study-related tasks, including a self-collected capillary blood sample for assay testing and health related surveys.
