Products, prices, and total commitment
Function's first-party pages described more than 160 annual tests, with more than 100 in the initial round and more than 60 on repeat. Testing runs through Quest locations. Public membership pages showed conflicting current values of $365 and $499, so the active checkout must settle the membership price.
Function does not sell prescription treatment. Its price covers testing, clinician review of results, and health insights.
Rebody lists a price for each treatment. Examples include NAD+ nasal spray at $59.50 for the first month, then $119, and Sermorelin injection at $99 for the first month, then $198. That price covers the clinical review, prescribed medication, shipping, and messages with the care team.
A buyer may use Function to discover a lab pattern and Rebody to pursue treatment. That sequence still requires the Rebody provider to review the relevant history and data.
Provider review, labs, and fulfillment
Function states that it is a healthcare technology company and does not offer medical advice, diagnosis, or treatment. Its service organizes extensive lab results and provides clinician-reviewed insights.
Rebody is a medical treatment service. A licensed provider reviews the online visit and decides whether the selected prescription is appropriate. A partner pharmacy fills and ships the prescription when approved.
Function can help you find patterns in your lab work. Rebody evaluates and treats a specific concern. Some people may use both services, but they solve different problems.
