Pros & Cons

altRX

What we like

  • Tirzepatide costs $1249 a month, close to the $1249 median for brand-name 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 and shipping

Watch-outs

  • Semaglutide costs $1149 a month, 16% above the $990 median for brand-name semaglutide across the sellers we compare
  • 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
  • The FDA has issued altRX a warning letter. Read what it alleges: a letter flags a problem but does not by itself rule a seller out
  • 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
