Piper
What we like
- Shows its price before the medical questionnaire, so you can compare it without handing over health information
- The monthly price stays the same as your dose goes up
- The monthly price includes the medication, clinician visits and shipping
- Serves all 50 states
- We found no FDA warning letters issued to Piper
Watch-outs
- Ask which pharmacy fills the prescription before you pay, so you can check its license
- Its semaglutide and tirzepatide are compounded rather than FDA-approved, so they have not been reviewed by the agency for safety, effectiveness or manufacturing quality
