We publish prices and public records; we are not a clinic, a pharmacy or a medical service, and nothing here is advice to take, stop or change any treatment. Compounded peptides and NAD+ are not FDA-approved, and the FDA's position on several of them is changing. A clinician who knows your health is the person to decide whether any of them is right for you.
