CoreAge Rx
What we like
- Semaglutide at $99 a month, 48% below the $189 median for the same drug and form across this register
- Tirzepatide at $149 a month, 44% below the $267 median for the same drug and form across this register
- Publishes a price on its own site before the medical questionnaire, so it can be compared without handing over health information
- The monthly price is recorded as flat across doses, so it does not climb as the dose is titrated up
- The monthly figure covers medication, consult, shipping
- Coverage is published for all 50 states
- No FDA warning letter matched this operator when we searched our enforcement register
Watch-outs
- No dispensing pharmacy is named in our record, so its accreditation cannot be looked up from here
- 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
