Function Health is the better fit when you want a broad annual testing program and written health insights. Rebody Health is the better fit when you want a clinician to review a specific prescription treatment and arrange home delivery when appropriate. Function states that it does not provide medical treatment, so it does not belong in a peptide-clinic ranking.

The shortest honest verdict
These services begin at different points. The useful answer starts with the job the buyer needs completed, then compares the full fee and care structure.
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 prices the selected prescription pathway. Examples include NAD+ nasal spray at $59.50 first month, then $119, and Sermorelin injection at $109.50 first month, then $219. The displayed price includes provider review, medication when prescribed, shipping, and messaging.
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 measures broadly. Rebody treats specifically. The services can be complementary, but the purchase jobs remain distinct.
