Curve
What we like
- Semaglutide costs $175 a month, close to the $185 median for compounded semaglutide across the sellers we compare
- Tirzepatide costs $225 a month, 10% below the $250 median for compounded tirzepatide across the sellers we compare
- 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
- Names VialsRx as the pharmacy that fills its prescriptions, which most sellers do not
- We found no FDA warning letters issued to Curve
Watch-outs
- 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
WeightlessRx
What we like
- Semaglutide costs $174 a month, close to the $185 median for compounded semaglutide across the sellers we compare
- Tirzepatide costs $250 a month, close to the $250 median for compounded tirzepatide across the sellers we compare
- Shows its price before the medical questionnaire, so you can compare it without handing over health information
- The monthly price includes the medication, clinician visits, shipping and coaching
- We found no FDA warning letters issued to WeightlessRx
- A live video visit with a clinician is required before a prescription, which is slower than a form and is the more careful intake
Watch-outs
- Confirm it serves your state before you start the intake
- 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
Our Verdict
Curve wins this one, 7.5 to 7.3, above all for knowing which pharmacy fills the vial: it names VialsRx. WeightlessRx undercuts it by $1 a month, so if the monthly bill is what decides it, WeightlessRx is the pick.
